At one time, I lived in a house (My Great Grandpa's House) that didn't even have polarized outlets. So Dad took me to the hardware store every weekend. My Dad didn't know what he was doing and just attached the wires to the screws and that was that. I used to think at my young age, 6 or 7 years old "That can't be right" but then didn't give it much more thought. When I became a teenager, I found my Grandma's Time Life Books. One of them was wiring basics. That book and riding to the library on my bike taught me so much more. I love the work but I am just not able to physically endure it anymore, so it makes me really upset that I can't do it, and I get even more upset when those that can, choose not to do it right. My Mother bought so many houses, because she LOVED different ones at different times. I always found wiring that was all wrong, like outlets ungrounded, reversed polarity open air wire splices, real fire hazards. So I would rewire them. At one point my Mother said "I wish, just once, I could buy a house that you didn't have to rewire." I looked at her and said "Me too, Mother. Me too."

Many homes with 2 prong outlets have an equipment ground that is just not connected to the device (outlet). If there is a ground there is no need to this kind of outlet and they are $100+ each btw. If there is no ground at all your wiring needs to be replaced. Most older homes these AFCI GFCI outlets will not even physically fit in an old electrical outlet box.

Everything checked out except two outlets on the new circuits that were in interior walls that were NOT gutted. These two outlets were the last on their circuits and had the old two wires in place.

All very good advice, I have a very old house where I do this on non-critical circuits. Just note without the ground typical surge protectors will not actually protect against a high surge since there is no path to dump it to ground.

[@okaro6595]

Surge protectors have varistors between all the three connectors so they do dump the over-voltage to the neutral.

[@chuchuchip]

Within NYC limits in the past, BX & metal boxes were used. An aluminum wire was used to ensure of a ground connection along with the armor sheath of the BX. The screw tab on the adapter plug was to provide a mechanical connection to ground & the plug not to be removed. Power tools & most kitchen appliances were made with a metal housing. 3 prong plugs was to prevent electric shock. This failed though since in the infinite wisdom of some older folk was to either cut off the adapter tab or cut off the 3rd prong on a grounded plug. My father went nuts because I replugged his metal cased power tools! But I also replugged the whole house with 3 prong outlets & ensured there was a ground circuit for all the outlets. That's what my mother got for sending me to Thomas Edison Vocational HS. I was also an electrician in the US Navy & the NYC Transit system. I repaired electric trains 1:1 scale & wired my train club's layout room & layout.

[@randyhaxor]

Was going to say why didn't he check the box to see if it was grounded ??? Not sure if code allows him to make a grounding connection from a box to outlet as acceptable ????? In the middle of doing this in my parents nyc home, crazy how many lights/outlets were not not grounded. Thankfully the bx cable/boxes were for the most part grounded back to that... Tis true the elders of ze past didnt care about grounding in the past

[@maxheadroom8857]

@@randyhaxor now, you need to be careful about where you use NM cable. Mice and rats have gotten a taste for the plastic, and have chewed through PVC conduit and NM jackets when they've gotten into attics through vents and breaks in a wall. And for the old cotton cloth wrapped NM cables, termites have gotten into some of them as they eat away at wood studs in a house. Some building codes now forbid NM wire except in use inside plastered walls in new construction, due to rat and mice chewing up the wiring. The alternative now used is flexible conduit with 14 or 12 gauge wiring being fed through it to the boxes. If the new construction uses metal boxes, metal flex is used.

[@Sparky-ww5re]

Good info. For some of those folks in their younger years wondering why many very old socket have 2 slots shaped like a T turned onto it's side, here's a little history lesson: in the first few decades of the 20th century, when homes were being electrified for the first time and the abundance of household appliances became readily available and affordable to the middle class, there were two different types of plug widely used, the parallel, which resembles the type found on your lamp or hair dryer, and the tandem, which the prongs were in a straight horizontal line, and a battle fought between what would become the standard, very similar to the videotape format war, Betamax vs VHS. The tandem plug was officially listed for 15 amps, 250 volts, and the parallel 15 amps, 125 volts, sometime around the early 1950s. Just as VHS won over betamax in the mid 1980s give or take a few, several movies were available in betamax up to the early, to possibly mid 90s, the tandem plugs mostly went out of use earlier in the 20th century, it took some years for the standards to catch up, so to allow for the two different plugs, the old outlets could easily accept both.

[@jakesully5402]

Thanks Kyle !! That’s cool to know. When he first showed the receptacle, I was a bit perplexed. I know tandem is 250 volts and parallel is 125 volts, so I was trying to figure out what the heck that receptacle was all about.

[@Sparky-ww5re]

@@jakesully5402 speaking of never too old to learn, another thing to note on older electrical outlets and light switches, particularly the ones pre-dating the 1950s, is a marking something like: 125V/15A and 250V/10A. From the 1920s to the 1950s, lamp sockets were rated 10 amps, while general purpose home circuits were allowed 15 amps, but over 125 volts followed the 10 amp limit. Note those old t slot outlets would have no problem carrying 15 amps if not more at 240 volt, they typically overbuilt many devices back in the day. And though they wired these older outlets for 120 volts 9 times out of 10, regardless of whether they used the parallel or tandem prongs, there was the occasional exception, for example, you were inside an office or other commercial building from say the 1910s or 1920s, and operated say large fans, high powered lighting, etc so you had to be very careful to know what voltage was being supplied to the building in question before plugging stuff in ☺

[@charleshodgdon6168]

What ended the electrical issue? For Beta and VHS, it was porn. Porn movies made up most of movie sales. They decided as a collective to go to VHS. Beta was the better system overall, but the decision was based on sales.

[@Sparky-ww5re]

@@charleshodgdon6168 lol i learned all i need to know about movies sales. As far as the electrical tandem vs parallel plugs, not sure because that was way before most of us were born, but based off some of the electrical code and repair book i have, it seems like because of the two different voltages in common use beginning in the first few decades of the 20th century, when the majority of homes went from lanterns or gas lighting to the new fangled electric lamp for the first time, the fact there were few if any standards for wiring, and the obvious hazards of connecting something to the wrong voltage/current rating, they needed something that would be standard across the board to prevent plugging into the wrong power source, so they finally decided to used parallel plugs for 120 volt 15 amp and tandem plugs for 240 15 amp, such as might be for a window A/C unit or large electric heater before the code began requiring grounds on all the outlets in the 1960s.

[@nicholasragusano2284]

When putting the wire in the screw, make sure it is on the left side of the screw, not the right. On the left allows the screw to keep the wire tighter. Also, many of the old boxes were actually grounded. That should be checked out. If that is the case, then to complete the process, attach a ground wire to the box and then to the ground connection on the new outlet.

[@richardcase1653]

If the box is grounded, a regular receptacle should be grounded by the ears attached to the metal box. On a GFCI you would want to install a jumper wire as noted.

[@maxheadroom8857]

@@dan9809 your bathroom outlet box is using a shortcut to grounding by being grounded to the cold water pipe below it. As long as a plumber or handyman doesn't repair the plumbing in the future with PEX or CPVC plastic pipe, your grounding in the bathroom will be fine. My house's electrical ground is attached to galvanized steel cold water pipes. When I eventually have it repiped to copper type L pipes, the plumber will need to make sure the ground wires on my galvanized pipes get clamped onto the new copper lines to maintain proper bonding. Those copper wires you see in your basement are also likely grounding wires for outlet boxes to ground them from behind to the cold water pipes. Your panel box should have a ground wire coming to your copper cold water pipe to ground it as well. As for the metal waste water pipe, cast iron was commonly used for decades. As it leads out to the back yard, it gets attached to clay 4 inch pipes. If that cast iron pipe is a 4 inch diameter pipe, it's a toilet line leading to the main sewer line running through your back yard.

[@eniszita7353]

I figured out why a "ground fault interrupter" works without the ground. If *you* are providing the ground (e.g. getting a shock) it detects that more current is flowing through the hot wire than the neutral and trips. That is, when your body is closing the circuit between the hot and some other ground (like touching a faucet), so the neutral is not carrying that current. I wish that other places explained this.

[@rydfree]

Yep you got it . Most people including many electricians do not understand how it works . The hot and neutral wire should be balanced . If they are not then the GFCI assumes some current is leaking via another path and trips .

[@okaro6595]

The word "ground" confuses many. In other counties different terms are used. In Britain it is known as an RCD (Residual current device), still not very clear. In Finland it is called what translates as fault current protector. I think it would be clearer if they dropped the word "ground".

[@Thumbsdwn]

Good explanation. The ground in a GFCI functions exactly the same as in a normal receptacle (if connected properly), providing shock protection to the user of the equipment, assuming that the equipment has a plug with a ground prong.

[@virginia7125]

I have one circuit in my house where lightning once hit & burnt a neutral wire out. A new neutral was run to another nearby circuit. The hot should have been terminated & extended to the box. Acts like old knob & tubing wiring creating emfs in the improperly wired circuit.

Many homes with metal boxes were original wired with a bare (insulated) copper ground. It is attached to the outside of the box, you can't see it. If the box was grounded then that faceplate screw would likely be a ground . However, over time, contractors and homeowners inadvertently cut the ground wire without knowing what is was. This is because the original contractor would run one wire, horizontally over the face of the studs, from box to box, room to room. By cutting it in the kitchen area you could disable it throughout the rest of the house.

Just wanted to add that you get the same effect by using BX cable and metal boxes, which is how I was taught many years ago.

[@dexta32084]

I had an old house with two prong outlets I changed out shortly after moving in. The cabling was a braided tar 14/2 romex, plastic insulation, and a 16 gauge ground. The ground wire was often spiral wrapped around the end of the stripped braided sheathing and clamped to the metal box, grounding the outlet through the box. You had to be careful grounding the outlet directly as the 16 was fragile once you unwrapped it.

[@WanderingStil]

Where was this done and what was the box ground wire attached to? If you don't mind me asking.

[@maxheadroom8857]

@@miguelalvarado2343 I grew up in the house I now own. It was built in 1955, under 1956 NEC regulations taking effect months later. My folks bought the house in 1961 from the original owner who built the house himself. He used Square D XO circuit breakers which were the state of the art at the time. The boxes grounded in my house are the bathroom outlet box, the light switch box to the bathroom light, the central heating outlet leading to the heater's blower motor, the outlet in the old laundry room next to where the sink was (laundry got moved to the detached garage), the outlets near the kitchen sink, the outside porch light boxes & the switch boxes to the lights and all fixture boxes in the detached garage. The fixture boxes in my garage, however, originally did not have 3 prong outlets in them for many years, even though they were bonded. Since all my breakers are in 1 panel, I can run ground wires from an ungrounded box up to my attic, and run a ground wire from a grounded box up to the attic to share it with the other circuits. I currently need to replace a rusted box in my kitchen and put in a GFCI in place of the old 3 prong outlet in the box. When I chip away at the plaster to access the old box and the stud that the bracket is mounted to, I will run a separate ground wire to ground ungrounded circuits with.

I done reno in the very old house, a spiders web, where receptacles and switches are mounted without boxes into walls and thick baseboards. Absolutely crazy. No marrettes, no 'clamps' at holes in boxes - twisted wire and hockey tape in some of them, bent nails hold wires in place. The worst of it is that BX they use barely passes through the holes they made and replacing the 'plugs' is almost impossible in some locations. At this point I basically rewired from scratch most of the ground floor with new BX. The locations where with old BX that couldn't be replaced have separate breakers.

[@RKelleyCook]

Whoa, I has those double-Ts outlets in my current 1950s-era house. Good thing you had the detector and didn't get zapped like I did when replacing them. Turned off the breaker, the lights on the traditional LED receptacle/GFCI tester went off ... and yet ... there was still power. Turns out those double-Ts were a NEMA 1-15P / 2-15P combo unit that went away in the 60s. They are ungrounded 15 amps, but have both 110V & 220V. And despite turning off the breaker, the other hot phase of the outlet was still on. Needless to say, I quickly bought a Square-D handle-tie and corrected the panel breaker.

[@Sparky-ww5re]

Wow, that's pretty scary, never know what dangers lurking around in an old house. History lesson at least for those in their younger years. The original reason for the double t slot, and the reason they were banned in the early 1960s, had nothing to do with 110 or 220 volts. In the early part of the 20th century, just as many homes were wired up for the first time, there was two different plug types in use, the parallel prongs, what we today call nema 1-15, as well as the tandem prongs, what we today know as nema 2-15. So most older receptacles like the t slot could accept either configuration. The parallel prongs were officially rated for 110 volt in the 1930s, but the tandem prongs were UNOFFICIALLY for 220 volts until the 1950s, and though most all of the older outlets were indeed wired for 110 volt, not all were, especially in some older commercial buildings such as office buildings, so you had to be certain which was supplied before plugging stuff in. Hence many old outlets , were marked 125V 15A/250V 10A, accordingly

I had an old house with two prong outlets I changed out shortly after moving in. The cabling was a braided tar romex with 14/2 and a 16 gauge ground. The ground wire was often spiral wrapped around the end of the stripped braided sheathing and clamped to the metal box, grounding the outlet through the box. You had to be careful grounding the outlet directly as the 16 was fragile once you unwrapped it.

The ground wire for your outlet goes to the bonding system. Which is designed to trip the breaker is something is wrong. The cold water has nothing to do with tripping breakers. If there is a plastic pipe in the cold water system, or perhaps the cold water isn't bonded to the neutral at the panel, or perhaps there is a valve of sorts between the outlet bond and panel bond to the cold water, you don't complete a smooth path for the breaker to trip, and instead you just electrified the cold water in the house

I have seen homes where there the wiring has a ground, but where there is a two-prong outlet. In these cases, the ground wire is tied to the box. In these situations, you can use an adapter and screw down the lug and the result will be grounded. But, of course, in this situation you could also just replace the outlet and use that ground wire, which is even better. Of course, it appears that this doesn't apply to your situation, so using a GFCI is your only option if you don't want to run new wiring to the box.

There is a problems with the adapter: does it produce low enough impedance path for the ground? If you use it at least test it afterwards. Changing the socket is way better.

[@Sparky-ww5re]

The master electrician i am working under, the house he purchased 14 yrs ago was built in 1957, he has been doing electrical work for over 30 yrs, so he knew exactly what needed to be done. He replaced the 60 amp main and range pullout fuse panel with all square D breakers, while doing so, to his surprise, the original wiring, the fabric braid NM wire, did have a bare copper ground wire, but was very small maybe 16 or 18 guage, with all two prong outlets except one bathroom, which had a GFCI outlet when he purchased the home. What the builder who wired that home did was wrapped the ground wire around the outside jacket of the cable and clamp to the metal boxes. If you were just replacing the old outlets you would never see the ground wire, and assume the old NM did not have a ground, as most of that era didn't.

[@Shamino0]

@@Sparky-ww5re I saw the same thing in my previous home. Although built in the 60's the basement wiring used that same fabric-wrapped NM wire. I suspect it was taken from someone's junk pile because the rest of the house is using normal NM wire. In my case, there were 3-wire outlets with the thin ground wires were tied to the ground screw of the outlets, with a pigtail also going to the box (using an extra screw). Years later, when I did a basement reno, we removed and replaced all that junk with modern 20-amp NM wiring.

@@dougbrowning82 very interesting, to know that fabric wrap NM came standard with ground wire since the late 50s, as the NEC didn't require grounded receptacles aka three slot outlets until 1962, though homes may still have ungrounded receptacles even later than that as there are parts of the country that do not always adopt to the latest NEC. In the case of the 1957 home with the thin ground wire and fabric NM connected to two prong outlets, rewired by the electrician I am under, my thought was the home was built by a very wealthy person, who was just future proofing it, before we started using 3 slot outlets. I guess in that case, the bigger question would be does that thin ground wire offer low enough impedance to operate the overcurrent protection device in case of a fault, such as the motor on an old metal cased electric drill grounding out to it's housing.

Yes these sockets were designed to accept both the parallel blade and the "Hubbell" horizontal" blades that were popular in some areas into the 1930's. You may also come across a type that has four slots, two for each type, in one opening of a duplex cover. If you have an antique appliance with a Hubbell plug be careful not to insert it into a 240 volt socket as it will fit.

[@Sparky-ww5re]

Yes good point, the older Hubbell "tandem " plug as it was called, WILL fit into a moden NEMA 6-15 /6-20R such as you might have in your living room or garage for an air conditioner, air compressor or large electric heater. That being said while it's often tempting to keep an antique appliance in the family if it has sentimental value, I'd probably advise upgrading it with a modern three prong cord and plug since most vintage items had a metal casing or at least some metal parts.

[@benkeysor7576]

For the ones that don't understand the reason for a GFCI with no ground is because in the event you have an appliance that has a hot wire that gets damaged and starts touching the metal shell that outlet is still going to detect a ground fault and trip. If that was a regular outlet as soon as you touched that metal shell you're getting a nice shock. It also prevents possible damage of whatever you have plugged in, in the event there is a problem. Of course it doesn't completely solve the ground problem but it's the next best thing. I actually plan to do this in my finished attic that still has some Knob & Tube wiring that is tied into 1940's/50's Asbestos wrapped wiring, which goes to the outlets & lights. It would be nice to have a ground but it's not possible without a complete rewire.

[@jakesully5402]

Ben, bring in a licensed electrician in your case. Let them cut holes to replace those K&T wires. I was in a scenario like that one time to “go in and get rid of the KT up in the attic”. Another electrician had SUPPOSEDLY rewired the house, and had actually ran new grounded lines up to the attic. Well, I quickly discovered why he didn’t bother to eliminate the last remaining runs of KT. There were hidden junction boxes, or free air splices that I never did find. The more I dug, the more problems I was finding. Switched neutrals, plugs screwed to wooden baseboard trim with no boxes. I had to call the boss to tell him we are either “all in” to fix these problems, or we have to suggest the electrical inspector come in and do a safety inspection. Unfortunately, we did not get the opportunity to make everything safe in that house.

[@paulstandaert5709]

I will add that because most people don't know how a GFCI works, it works by comparing current at both the hot and the neutral to make sure they are equal. After all, what flows from the hot has to flow back through the neutral. If the electricity goes anywhere else, such as through a human body, it is not returning on the neutral, thus the current flows between the two will be different and the GFCI opens the circuit and kills power to the outlet.... supposedly before it will zap you.

[@THE-michaelmyers]

@@paulstandaert5709 Yes, A lot of people think a GFCI is more like a circuit breaker in how it functions. Another myth is they will last as long as a regular outlet. I replace my GFCIs every 3 years.

Clearly seemed to be the "behind the bed" outlet intended for a bedside clock and two bedside lamps. The house is full of the rubber and braided cloth insulated wiring typical of the era.

In the late 60s the house was in the way of the Interstate, so it was bought and moved onto a new basement foundation, where in the early 90s my wife had a contractor finish the basement and wire it up (poorly). While I eventually fixed the basement grounding problems and the incorrectly wired GFI outlets & 3-way switches, I left the original attic wiring alone except to install new switches and outlets throughout the upstairs. But it always bugged me; 60-year old wiring protected pretty much only by a non-leaking roof and a lack of mice/rats, and half the house had no ground connection. I was eventually going to get a buddy to help me strip out all the old wiring, but we decided to sell the place before I got to it.

One machine was powered by an old 2 prong outlets with an adapter to 3 prong. The other vending machines was wired by a 3 prong outlets. Because of impedance, one machine had better grounding. Also refrigerator motor tend to go to ground. When Michael pushed between the two machines, he created a grounding path between the two machines and was electrocuted.

Leave clock plugged in and walk to breaker panel. Flip breaker walk back and see if the clock is on or off. Unplug replug. Wait. Check for the clock lights. No lights would suggest no Power. I grab a tester/ voltmeter and double check all circuits. No lights/beeps no Power. Commence electric work. When finished, rewire if necessary, plug clock back in. Flip breaker. 1 of 3 things will happen: 1. the clock will turn on and that's it.👍 2. The clock does not turn on. Bad wiring. Redo/ check with voltmeter. 👎 3. The clock turns on for a hot second before it metls, explodes or smokes. Sometimes makes popping sounds or a very loud pop. This means too much power ⚠️⚡🔥🧯 (perhaps a 240v instead of 120v) a good voltmeter should tell you this going in but sometimes they fail. Sometimes pre done wiring is insane. Safer to have an alarm clock No one cares about explode, melt or light on fire than risk your house full of stuff later on.

[@arthendrickson4860]

The GFCI receptacle wired without a ground works because the fundamental operation of the GFCI receptacle is to trip if there is an imbalance of current between the hot and the neutral. If the GFCI receptacle senses an imbalance (e.g., more current being supplied by the hot lead than is being returned to the neutral lead), the GFCI receptacle trips. Typically, the tripping point occurs when the imbalance is greater than 5 mA. Typically, circuit current imbalance occurs because of some defect or misuse of an electrical appliance and current flowing through an individual who is standing on some grounded surface such as the floor and/or touching a grounded device (e.g., water faucet) while using the appliance. The GFCI receptacle does not protect against overloads or shorts. That is the responsibility of the breaker/fuse at the load center panel. It should be noted that a GFCI receptacle without a wired ground will not detect a ground fault in some attached appliance until a ground fault occurs through some other ground path such as a human.

[@oldtimefarmboy617]

I understand the traditional nomenclature when speaking about the different wires in a typical household wiring circuit. But I believe that it is important to let everyone know that with alternating current (AC) both the black and white wire are hot. The main difference between the black and white wire is where on the transformer coil that the wires connect. The two black wires entering the circuit breaker panel connect to ether end of the transformer's 220 volt AC coil while the white wire connects in the middle of the transformer's 220 volt AC coil. Because the white wire connects to the center of the transformer's 220 volt AC coil, it gets only half of the 220 volts AC the whole coil generates, which is why any device connected to one of the black wires and the white wire will receive 110 volts AC. That is also why any device, like and electric oven or clothes dryer, that connects to both black wires will get 220 volts AC. This also means that the white wire is only "neutral" because it connects to the center of the transformer's 220 volt AC coil. And because electricity must make a complete circuit to perform any work, an amount of electricity must flow through the neutral wire equal to the hot wire. This also means you can be electrocuted just as easily touching the white wire when energized as the hot wire. Alternating current alternates the direction it travels through a circuit and, in the United States, travels both directions alternating direction 60 times a second (60 hertz).

[@codedGiraffe]

Yes, however the white return wire is bonded to ground in your service panel. This means the white wire holds 0V relative to ground. Only when one of the hot black wires is connected (from either side of the 240v feed) does the circuit become live with 120v relative to ground since it is split phase. Only when both sides of the phase come together in something like a 220-240v socket such as a 14-50 are both hot wires supplying voltage relative to ground.

[@oldtimefarmboy617]

@@codedGiraffe You are forgetting that electricity MUST make a complete circuit. You are talking about ALTERNATING current, not direct current. ALTERNATING current means the flow of electricity changes direction periodically which also means that the source of current from the transformer is the white wire as often as it is the black wire. In the United States the current direction alternates approximately 60 times a second. The white wire holds a zero or minuscule volt potential relative to ground because it can not return to the transformer through the ground. If you take the white wire for any circuit and put an amp meter between it and the bus bar and turn on a device on that circuit you will get an amperage reading equal to what you would get if you did the same thing with the black wire going to that circuit. You would also get the same voltage potential. The ground serves two purposes. If the wires were to somehow come in contact with the metal skin of a device, it will enable enough current to cause the breaker to flip to the off position which would break the completed circuit at the service panel rather than the device switch. It also enables static electricity from whatever source, like a direct or close strike by lightening, to go to ground. Something that is important with integrated circuits where a static spark equal to what happens when you reach for a door knob is the equivalent of you being struck by lightening. kzbin.info/www/bejne/hl66ZWWqoJKZjcU

[@robbruce2128]

Old Time Farm Boy, I'm not gonna go grabbing a bare energized neutral line anytime soon, but when properly wired you shouldn't see any significant potential between neutral and ground. As Drew told you, the neutral is bonded to ground at the panel, so if you see 120VAC on the neutral, you've got wiring issues. You can test this with a fun physics experiment: Get one of those neon test lamps, stick one probe end into one of the terminals of the outlet and attach the other end to a something big and capacitive. Your body will do. The neon lamp will glow when plugged into the hot, but not the neutral or ground.

[@oldtimefarmboy617]

@@robbruce2128 And as I clearly stated and you obviously did not comprehend, electricity must return back to its source to complete a circuit. Only the black and white wire are connected to the source, the transformer coil. There will be no potential voltage between the white wire and the ground because the ground is not part of the circuit as long as all wiring is sound. The only reason why there is any potential voltage between the black wire and the ground wire is because the ground wire is bonded to the white wire in the supply panel. And the potential will be the same as if you measured the voltage between the black wire and white wire. Break that bond and the voltage potential between black and ground will be the same as white and ground. Nothing or so low as to be insignificant Either way, using a meter or if you just used a piece of wire, you are creating a short circuit. The meter measuring the voltage has enough resistance to make the current nearly zero. Using a piece of wire will smoke the insulation and melt the wire if you bypass the breaker in the process.

[@BitSmythe]

3:05 When stripping wire, DO NOT rock back and forth as shown. This can easily score the wire (as seen at 3:11), and copper wire can break at that weakened location. Best way to strip is to bite with the stripper once, loosen your grip, rotate 90°, bite again, then pull off the insulation. Just be sure to use the correct wire size indicator on the tool. Not sure which size? Start with a lower number (bigger wire size). If the insulation won’t release, then try again on the next smaller hole. Important note: Not trying to be critical, only to use the best safety techniques! And no need to say "how's it going you guys."

If it was a metal box and metal conduit was used all the way back to the breaker (or fuse) box, one of those two-prong to three-prong adapters could have given you a real ground if it was screwed in with the center screw. You might actually find that in an old house with two-prong plugs. If you think that might be the case you can measure the hot side to the box to see if it has 120 VAC across them. Otherwise the GFCI outlet is the way to go.

[@renegadeelectrical1264]

First thing you'll need to do is contact your insurance company. File a claim, and they should send out one of their preferred electricians to take care of the work. If they don't. Pick the contractor with the best reviews near you. Document everything, see what you can get reimbursed for. If for some reason you absolutely must DIY this, just know it involves cutting the damaged circuit out, and installing a replacement.

If both wires are the same color, get a multimeter and test continuity on each wire. With the power off, find a nearby outlet or plug an extension cord into one. Set your multimeter to continuity mode, and then see which sockets/wires produce the noise in combination. Then you will know which wires are which.

If you don’t have a ground wire to work with, how is this any safer than the adapter you showed at the beginning?

[@Shamino0]

A GFCI does not require a ground wire to function. It does not look for current on the ground line. It actually works by comparing the amount of current on the hot and neutral lines and trips if they are different (meaning some current is going elsewhere). An adapter dongle, on the other hand, simply connects the device's safety ground to the screw terminal at the center of the outlet. But if the outlet isn't grounded (e.g. to the box) then it accomplishes nothing - it becomes no different from simply cutting the ground pin off of the plug (which you should never do).

Several people have commented on the "difficulty" of hunting down the first receptacle on the circuit so that they can use only one GFCI outlet and daisy-chain the rest with standard outlets. What's the best way to find the first outlet? Do you have to one-at-a-time disconnect all the outlets (starting with the most logical one) and then check if all the remaining outlets become non-functional? Is there another way? Thank you!

[@Jason_Van_Stone]

You're pretty much on point. Just have to shut off the breaker, then test to see what has power/what doesn't. Usually it's the closest to the panel, but I have found some Mickey Mouse home runs that were at the very end of a room.

[@sams7725]

There is another way. A much better and faster way. You buy a fox and hound, or a similar tool. You hook it up to the outlet or device that is not powered (you could pull the circuit breaker and hook to it, Once the circuit breaker is removed, there is no power to it. You would test anyway just as a precaution; sometimes crazy things pop or are wound at the oddest times.) and point this wand or the hunt tool at outlets and lights; if it beeps or lights up, you know it's on the circuit. They used to be expensive. Today they aren't really expensive. You can look them up on KZbin and or the web to see what they cost and how they work.

[@willpas1957]

Great video! You made it simple, and easy to follow. I'm replacing multiple outlets with GFCI's. I have one question. Years ago, I plugged in a paint sprayer to a knob and tube outlet. The sprayer was sitting on grass. When I went to move the sprayer, I was shocked by touching the metal area of the sprayer. Would a GFCI replacement have prevented that? Did the fact that the sprayer was sitting in grass that may have been a little wet cause the metal to be charged? If not, I would be concerned if say, a metal toaster could carry a charge. My guess is it wouldn't.

[@islanddave8606]

I would guess that your neutral and hot were switched. If it was a two prong outlet, you could have flipped the plug . The paint sprayer was probably grounded to the Fram. when you flip the plug, it will put the neutral on the Fram

[@okaro6595]

@@islanddave8606 Nothing is grounded through the neutral.

[@okaro6595]

An electric shock generally means that there is a fault in the device or the cord. A GFCI could have triggered because it was on wet ground. In general you still get shocked in case of a fault but the GFCI cuts the power before it can cause serious harm. I would not trust a GFCI alone in a wet place.
