You're learning from your audience and your own personal experience, and making sure that we get to share in that learning experience. That's what I really appreciate about this channel.

[@bedshapd]

@@jajajajajajajajaja867 agreed. I am not sure why is everyone hung up on plug/unplug aspect. It is a dryer plug and likely not to be unplugged unless there is service needed or "maybe" to clean the vent in which case the cord is usually long enough to allow access to the back of the dryer. i do applaud the shorter version of this video where this guy does not force us through a 40 minute session of him enjoying the sound of his own voice like so many others.

[@N-hunter]

Another note is to make sure that the box is secured well to the wall if you plan on plugging and unplugging with any frequency. Those receptacles have a fair bit of grip strength, so normal drywall anchors may pull out of the wall. 3” Screws into a stud or tapcons for concrete are best

[@Toyotajunkie]

I agree... I rip the "high-end" anchors out all the time, and thus do not use them in anything that I do. I think it is worth it to remove drywall and add a brace if there isn't already one. In that case I wouldn't use 3", but you catch my drift.

[@nathanplatt5517]

You're going to want to double-check that ground screw you put inside the box, it looked like it was loose and the wire was moving around and you also might want to secure the actual box to the wall a lot better.

[@frankmortensen7651]

Nice video, I do have a suggestion if you are looking for more strength for repeated plugging/unplugging here. The weak spot in this is the 2 screws that hold in the mud ring. If you use the Hubbell-Raco 696 Masonry Box you can tap in 2 more screws and have every corner held down snug. There are other boxes you can use, but I like the way the metal piece with the screws goes the length(or width) of the box instead of a little tab in the corner. Also I couldn't tell too well, but it looked as if your drywall was giving way a little when you pulled on the box, so it may be installed with drywall anchors. If you ever have an opportunity to get in and put a stringer between the studs to mount the box to it would make the whole plug rock solid. Overbuilt is better imo. Also want to say, that nothing in this video is bad advice. I am just contributing some ways to make it even stronger.

[@returner323617]

Great to see you're taking feedback and recognising when something's sub-optimal. With regards to the original install, Id did think the over-sized faceplate looked weird, and - as others have noted - possibly some form of wall bracing might be a good idea, as the you might end up pulling the socket off the wall... As always, great content.

[@EverydayHomeRepairs]

Yeah, some addition bracing in the wall would be helpful. Plugging and unplugging will definitely put drywall anchors to the test. I will be installing a charger in that area soon and might just take a piece of 3/4" plywood (painted white) to sure up the box and charger.

Romex in the conduit (you can see the sheathing) is a no-go in many jurisdictions

[@andrewt9204]

Could be true. I don't think it's strictly forbidden in the NEC, but I know it changes the fill calculation, or maybe it changes to only having the one cable. I looked it up a long time ago but can't remember anymore. As long as the breaker is sized for 60c conductors. Looks like 6ga, so he's good with a 50A breaker. If 8ga, then only 40A. Normally I would never do this, but the extra protection of EMT/FMC in a garage isn't a bad idea. Not sure why he didn't just use THHN though, unless he wasn't able to run EMT all the way back to the panel. In that case I would have ran the NM cable to a disconnect at the garage penetration, then ran EMT+THHN to the receptacle.

[@Keifsanderson]

​@@andrewt9204I'm in a similar situation running a circuit to a garage wall opposite my panel. Romex from the panel up the wall, exposed in the attic across the ceiling, then down through a hole in the ceiling to the receptacle. I want to put the Romex in 3/4 EMT for tidiness and protection, so I considered transitioning to THNN exiting the attic, but didn't do it because I like to avoid unnecessary junctions. Increased resistance and more chances for things to go wrong. I'm not an electrician, though.

[@stanrosenblum4669]

That original install was done by a master electrician who has his own fantastic channel. We all make errors but as others have pointed out EMT if properly installed is an acceptable ground Also you could wrap the ground wire around the box screw and then to the receptacle. Great channel Keep pushing for Klein combo or Milwaukee ecx drivers especially as torquing is becoming more of a standard and not a suggestion. 👍🏻👍🏻👍🏻

[@Jgalaski8438]

Was looking for someone to comment about just wrapping the wire around the screw. I was starting to wonder if that was against code.

[@knifeswitch5973]

No, the EGC needs to be pigtailed now. Can’t just do a loop then hit the device.

[@pizzabar3527]

The EMT is only a ground if it goes all the way bay to the panel, which is probably not the case here.

[@jessebutryn]

If that metal conduit is grounded that should meet any code requirements for grounding the box. Also those "combo" screws on the original outlet will also accept a robertson drive which will allow you to put as much torque as needed.

[@paaao]

Not true. The conduit is not required to have the grounded conductor tied to it due to the fact that emt and the fittings are considered a complete bonded path, but the ground conductor in the cable, bare or insulated should be tied to every device that has a ground terminal, and every metal junction box it passes through. If a ground fault condition occurs on a 50Amp ckt like we have here, or any other smaller ckt for that matter, you want the 10 awg wire that travels back to the panel's ground bus bar carrying the fault current, as opposed to the EMT. The code allows you to avoid bonding the EMT because if a fault occurs in contact with a section of pipe or a fitting, there should be a grounded junction box, or panel, that is tied directly to the grounded conductor within a short enough distance to return the fault current back to the source, and allow the breaker to trip. That's the intent of the code. The intent is not for you to rely on, or assume your conduit and fittings are sufficient to carry fault current on their own back to the source. I think you're misinterpreting what the code is saying. If a junction box has a splice, or connections/device, then it should be grounded. Bonded is not the same thing. EMT is considered bonded to jboxes and panels that it connects to. That has nothing to do with grounding panels and jboxes.

[@greg_zenger]

@@paaao Sorry, but you are mistaken. The EMT can be utilized as the EGC in accordance with NFPA 70 Section 250.118, and there is no requirement to bring an additional ground conductor to the box. If the receptacle does not have listing and associated markings to allow grounding through its yokes, then a grounding pigtail does need to be brought between at least the receptacle and the box. It has been proven that all sizes of EMT conduit are capable of handling the fault currents of the largest services, feeders, or branch circuits that they can contain. The biggest exception is in NFPA 70 section 440.9 which requires a separate grounding conductor in rooftop EMT serving HVAC equipment. When installed correctly, EMT can provide an excellent EGC path, however the HVAC trades tend not to be the best electricians, so the code has had to compensate for them. Its unfortunate, but here we are. As a specifying engineer, I often require a separate ECG to be pulled into EMT when I can justify the cost. (I almost always can). Sometimes there are box fill, conduit fill, labor hours, and situational conditions that making eliminating the ECG the correct option. In my experience DIYers tend to go above and beyond when it comes to supporting cables and conduit. They are working on their own project and they tend to aim for aesthetics and in general just "overengineer" certain aspects. Nothing wrong with going above the code, after all the code is the bare minimum needed to be legal. The biggest issue is the quality of components DIYers tend to have access to. Better quality parts from Appleton/Oz-Gedney, Cooper/Eaton, ABB/T&B, etc. available from the supply houses can really make a difference in an installation compared to the economy brands typically available at the box stores where DIYers shop. And of course, there may be local amendments to codes that may require an EGC in EMT. Your company might have a local policy to always install one. In general, I would consider it a good idea, but it is usually not legally required.

[@docferringer]

Yeah, he's got a couple of videos going into the different screwdrivers that will work in those fasteners. The "combination" fasteners will take a robertson/square drive for sure, but the cheaper the fastener, the more likely you cam out or break the bit, even a square drive. Cheap galvanized screws have to account for the changing dimensions of fastener before and after electroplating, so it's pretty common for a cheap-ass manufacturer to go one bit size up and then rate the bit size one lower (so square #2 fastener HOPEFULLY galvanized to a #1 square). If an outfit is cheap enough to do that then they are going to have little to no QC to see how close they are. The beauty of combo/ECX bits is you can use that smaller #1 size when the #2 is too tight, and you can be sure of AT LEAST one of the slotted/philips/robertson carve-outs being close enough to avoid stripping. But for every other application under the sun? Hell yes to the Robertson!

[@paaao]

@Greg Zenger Guess you're right. I was always taught that it's a no no, because inspectors often fail you unless you can prove the emt path is actually continuous and will never be interrupted or modified, and that the ckt within will never be used to feed any motor driven appliances. Which can be tough to do in a commercial environment. In residential, sure.

[@donh6416]

@Greg Zenger EMT is permissible as a grounding conductor. But the problem the AHJ's locally point out, set screws don't always stay secure, which breaks the integrity of the continuity. Hidden couplers make it difficult to troubleshoot continuity checks. I'm with you, pull a ground conductor. All the time. The poor quality of EMT connectors & couplings in my mind make necessary.

I think DIYers can accomplish a lot that the pros can't/ won't because they have a personal investment. Tons of tradespeople and contractors, just don't give a damn and they will tell you that.

When comparing outlets, look at the blade contacts inside the outlet. Leviton has a lot less contact area then other outlets.

[@russellstephan6844]

I've always used RV electrical outlet boxes when putting 240 volt service in places like shops and garages. The locking cover is just extra safety insurance for a number of reasons.

[@milesvinson]

I was going to make that suggestion. I especially recommend the ones that have a disconnect means combined. It's best and safest practice to throw the disconnect (turn off the power) before plugging or unplugging cord connected devices greater than 20amp rated. Another option I recommend is using a 100amp disconnect and mount the receptacle in the bottom. An RV park disconnect with the receptacle already installed is the easier (and usually cheaper) option. The only thing is those usually aren't in stock locally. Get online and order them ahead of time.

The issue with RV boxes is that the plate is made for the cheaper $15 outlets. They are only 2" across. The Hubbell he used and other commercial grade outlets are all 2.5" across. I have yet to find an outdoor box which will take the larger, commercial grade outlets.

@@4x2-ev Well, I have a drill press and also use the good outlets. ;-)

[@KameraShy]

Conduit (RMC, IMC or EMT) is an NEC-accepted ground path. No additional grounding wire is needed. The metal box does not need to be grounded separately. However, that presumes that the origin of the conduit itself is properly grounded, which may not be the case where wiring spawns from a hybrid of different types. My house is all conduit and all my receptacles test as correctly grounded. Commercial grade electrical components are expensive, some exceptionally expensive, but will save misery in the long run. Commercial grade standard receptacles are only a dollar or so more, and my regret as a DIYer is not using them. Some cheap ones that get frequent use have now become sticky and will have to be replaced. It is different where they are only used to plug in a lamp that will not change for 10 years.

Many jurisdictions no longer allow conduit ground paths, especially in residential where the risk of Romex and other methods can interrupt the system. Never assume that just because the Code allows something that it is okay. Check with your authority having jurisdiction (AHJ aka inspector) to verify the demands of your area. If you use a metal box, you should ground the box. It is simply good practice.

[@aaron74]

@@MrWizards1974 In this particular instance there is *not* a conduit bond to the panel. The conduit in this instance is just sleeving for NM cable that runs inside the conduit. The conduit terminates above the panel and the NM runs behind the wall from above and has a box connector at the panel. Therefore the only bonding of the conduit is made at the far-end receptacle box.

When safety is involved it is better to "wear both belt and suspenders."

[@jameskrivitsky9715]

From a practical point of view ( semi-trained in electrical work ) since you originally had some slack in the bare gnd wire, what is wrong with making a small hairpin turn to go around one of the metal box GND screws , fasten it to the GND lug of the box and then attach the tail of the bare GND wire to the outlet ? I would think that an un-cut conductor is better than a WAGO splice with less surface contact.. Once connected, then push the wires and outlet back into the metal box with the upgraded face-plate.

[@bobmitchell4532]

Excellent tip! A number of others have suggested the same.

[@802Garage]

By pig tailing you have a ground for the device and the box. If one of the two grounds fails, the other may still function, providing an added layer of safety. That's the usual logic I see anyways, though TBH it probably makes very little difference.

[@asuarezjd]

Nope, the Hubble was important and necessary to install but there was no grounding issue. You had a grounded outlet. Good video and I am glad you made it. I am also happy that you got an industrial grade outlet, the cheap oven ones will not do and can burn, they are not built for CONTINUOUS juice, the connectors inside are half the area and not copper. Yet, the ground pigtail, is good you showed and brought it to attention, nonetheless, the copper bar on the side (at 6:18) of the outlet as well as the bronze chip means that is a grounded outlet. Hence, when you connect the ground bare wire to the outlet it link, nexus, ties it into the plate which will then ground the metal box and conduit when you screw the plate to the metal box. In fact, it was more secured before because the ground wire was not interrupted and the WAGO lever nut is always another risk that it can come lose in addition to another connection which is not as tight. I guess what is done is done now since you cut and shortened the bare wire. So, no need, but is good to do for those with cheap outlets which are not the "grounded" type. I love that you mentioned to wiggle and retight the stranded wires, it is a fatal mortal sin not to, especially because they WILL loosen up and will arc or worse, fire up. Is always necessary to revisit and wiggle and torque again. Is a garage and you don't want 50 amps catching fire underneath the bedrrom while the family sleeps.

[@handymandad5613]

That is what I thought. Pigtail not necessary because outlet ground has the metal clip that mounts to the steel of the outlet, thereby grounding metal box

[@946towguy2]

Is there a reason you don't use an unbroken ground? I was taught that best practice was to put an eye in the ground with 2-3 twists and bond to box with screw, leaving a tail to attach to the receptacle. Then connect wires to receptacle and secure to box. Why add 2 extra points of failure and resistance?

[@bobmitchell4532]

Very good point as noted by many other brothers (and sisters) here. T Y!

[@asmoore82]

"put an eye in the ground with 2-3 twists" There's your guaranteed point of failure. Twist the copper and then smash it with a screw and then it will have to continue to flex every time the receptacle is serviced. And as an added bonus, it's going to leave your unlucky victim with a very short conductor after they have to cut off below your twists to make a new clean connection.

I'm not saying you made a mistake but when you cut the ground wire short to make your pigtail you may have created another violation. The code has requirements for free conductor length.

Nice Video, I have a 220 that I've been needing to install.

[@KRColson]

I noticed the ground lug will be at the 12 o'clock position. Depending on the configuration of the actual cord, you may have to place that at the 6 o'clock position. I know for a fact that for stove applications it's code in Canada to have it at the 3 or 9 o'clock placement as it's near the floor. That's so there is no stress on the cord pulling down from the top and also providing clearance for the cord "tail" from the floor. Just my two cents.

ground should always be on top to take the gravitational force on cords. also why ground is always round and thicker. Your canada ranges are typically on bottom and also different size/shape plugs (but also cannot point town since too low) and yes your smiley faces are, by design, upside down. they should be ground up as well. Hospitals do it to specification.. braindead home electricians don't

[@paulholmes1303]

One correction. You stated to install the conductors with no copper exposed. I believe code now requires a small bit of copper should be exposed to insure you are not possibly clamping on insulation A few mils of wire exposed will not create a short hazard and clamping partially on insulation creates arc/hot spot possibilities.

[@stickyfox]

I tried to install an outlet like this for my welder. My home depot had one outlet that fit in a regular box that had no cover plates in stock, a second outlet that only fit in a second kind of box that they were out of, and surface mount outlets. It was easy to decide which one to get.

Great video but..... I noticed that the wall was flexing just with you tightening the cover plate. With the use you described, I think I would have placed a board between the studs to mount the outlet on. In time, you may pull that outlet right off the wall as it looked like dry wall. The use of a good plug and outlet will be tight and hard to pull out.

EMT conduit can be used as a grounding conductor, per 250.118(4), as long as it extends all the way to the main panel or if used with NM cable (romex), there is junction box that is grounded with NM to the main panel. One can check continuity from the box and the main panel with the multi-meter. 250.118(4) states that electrical metallic tubing (EMT) are permitted as an Equipment Grounding Conductor.

[@richardholden420]

If the conduit runs all the way back to a nonconcentric KO in your panel or using a bonding bushing EMTs perfectly acceptable as using your GEC, but I would’ve put a green screw in the box and grounded it straight to the device to give it a little bit more of a path than just the yolk and screws holding into the box. Also, I would use compression couplings and fittings, instead of set screw if I was to use EMT as the GEC

[@benjaminvivar7855]

I’d like to mention for best practices. When reconnecting Used wires UL product steps requires to cut off the end of the previous deformed (used)bent wires and Re-terminate properly (remove proper length of insulation making sure wire is well seated in mechanical connector, torque to products specification) unfortunately that was not done.

When the 14-50 is in a metal box with metal conduit is the ground wire needed? All the houses in Chicagoland area have metal conduit in the walls and there are no separate ground wires in the conduit.

[@FoamyDave]

How do you feel about square crimping ferrules on the stranded wires? They are not required but I feel they help make a more secure connection with full contact to the screw terminals.

[@jamesmartello2218]

The only time the box is not grounded is when you remove the outlet. There is a metal strip that runs from the ground screw to the metal surrounding the outlet. When you screw the outlet to the metal box you then have a ground path. I did 90% of electrical work with pipe and wire, we never pulled a ground wire as the conduit was the ground path.

[@jeromyw385xp]

agreed and his one major mistake is useing that cheap rabbit connector instead of useing a proper wire nut to connect multiple wires for a firm hold and won't burn out over time as easy.

[@pld8993]

When you run the conduit complete to the panel, it is bonded to the panel and therefore grounded. In this case, the conduit is incomplete and does not go to the panel and is being used solely as physical protection. Therefore, the ground wire is required to be bonded to a ground screw in the box to maintain a grounding bond to the conduit. Also, even if it was a complete conduit run you cannot rely on the receptacle screwed to a metal cover as your grounding path unless the receptacle is riveted to the cover, so a pigtail directly to the receptacle is required. The ground wire in this installation must hit the ground screw on the box and the ground screw on the receptacle.

[@POLOAZTECA]

​@pld8993 Nice catch man. I missed that part and prolly the original installer did as well!

[@BlackEpyon]

The pipe SHOULD be grounded, if it goes to the panel, but pulling the copper ground wire makes sure of it, especially if that conduit should come loose or be improperly placed for whatever reason. Every joint along that conduit is a potential weak point. Always rely on that direct copper connection.

[@pld8993]

@@BlackEpyon A properly installed metal conduit system will not come loose any more than a properly installed wire connection will come loose, and it does not require or need a ground wire.

my thoughts 1. you need to better secure the box to the wall - it flexed a-lot 2. undo and re tension the terminals - if you had movement on the terminal bolts when you torqued them its ok, but if you did not this could mean that they are over torqued 3. check your ground strap screw it looked loose - this would make a bad connection 4. 4 screws are needed in that face cover - 2 screws might not be strong enuf that is why there are 4 holes, it is always better to err. on the side of caution with hi voltage/amperage 2 phase

in regards to #4, pray tell how would you add another two screws when there is only two tabs for screws?

[@toddwright662]

This is accurate advice. I made the mistake of installing a $20 outlet. It's lasted about 4 years, but recently I've been limited to charging at about half the normal rate (or less) after a bit as the charger plugging into it is sensing more heat than should be present and automatically reducing the current as a safety precaution. I'm only running 6' of 6 gauge from the service panel so it's definitely the outlet itself that is not up to the task. I've got my replacement ready to go and will be changing it out this weekend. Definitely check the outlet your electrician is supplying. Many are not yet up to speed and will just install the cheaper, lower workload options out of ignorance. I had to change out one in a different location after the electrician installed it. Also, a company named Bryant sources their product from Hubbell; they are the same outlet. You may find the Bryant cheaper; I got mine for $65 each at a time when Hubbells were selling for about double that due to limited supply.

[@jmyers9853]

[@pld8993]

The smartest way to install an EV charger, and the only way I will install them, is direct wire. There is no reason to have a plug-in charger unless it's intended to be portable, which is almost none. Your AC system, water heater, hot tub, built-in range, etc. are not allowed to be plugged in and neither should an EV charger.The EV charger manufacturers are designing many of their chargers to get around the NEC rule requiring permanently installed EV chargers to be hardwired. If we continue to see issues with plug-in chargers, I would assume that the NEC committees will tighten the rules at some point

[@ocsrc]

I personally prefer a single breaker box directly above the outlet, so I can disconnect before plugging and unplugging from it. With 240 volts you don't want to have power on when plugging and unplugging the cord. It is not required, but really good idea.

[@nicholasthon973]

A disconnect would also work.

[@j81851]

Kudos and an A- overall. I am very familiar with Wago I sold it during my part time career in electrical for about 5 of my 37 years in the trade and used in in my custom panel designs as we were a fabricator and sold panel build parts to others. I do favor the larger Scotch 3M screw on connectors (a type of wire nut on steroids) for grounds. A ground needs to be able to achieve 5 ohms or better resistance however the Wago is a spring tension contact over a very small surface area of the ground conductor. Code states the ground conductor and obviously by extrapolation the connection must withstand the maximum available short circuit current impressed upon it in a short to ground (primarily) or a phase to phase fault (secondarily). Your Edison system configuration there at your home with a single phase HV 2 Bushing and LV 120/240 Transformer out in the yard or on the pole can typically deliver a max of about 6500 amps surge current when shorted before any one of several protective devices operate. I'd be interested to see if the Wago device is listed and labeled for an intended purpose of splicing ground conductors. A substantial ground even on a 50 amp outlet is important.

It seems like a good idea to ground the box and I always do when I am doing something similar but is it required by code? In the old days, the conduit was allowed to serve as a ground. Is that now specifically precluded? Also grounding an outlet or switch by attaching it to a grounded metal box also seemed to be allowed. Is that grandfathered in? Is it specifically not allowed for new construction?

All the information you need is in chapter 9, table 1 and 2 of the NEC. For a single conductor the max fill would be 53% of a 3/4" EMT. That 6/3 is a whole lot larger than that. Now some inspectors will get this wrong and allow it base on the individual conductor fill but I just wanted to point that out for your viewers so they don't fail an inspection.

Typically the best way to ensure they are tightened properly is to 1) tighten the lug. 2) move the line around a bit. 3) loosen the lug again and reseat it 4) tighten the lug again 5) check to ensure they do not move. 6) torque them to spec checking twice. Stranded cable tends to compress in odd configurations so engaging and then releasing the terminal almost always insures the terminal connection has compressed as much of the contact area on strands as possible.

EV batteries are sealed and don't out-gas. Also, Tesla recommends NOT installing an additional GFIC because their charge has one built in. You may need to show that to your inspector and get the nod if you are on new code. He may also require the charger be hardwired instead of cord / plug.
