How To Safely Power Your Home With a Portable Generator

[@Jzzonem]

As an electrician, I can't help but comment that you need a bushing on that box to protect the wire as it enters the box. It will also keep the wire from being pushed back into the wall. Dont drill the hole right behind where the actual device goes because that limits your options on how to bend the wire around in the box. Great video!

[@jamess1787]

Quick question for you. Do you think that ground-wire is adequately sized for the circuit? Looks like a 16AWG wire with like 2 8AWG conductors?

[@Jzzonem]

@@jamess1787 It actually looks like 6/3 cable (since the ground is bare and the copper portion of the current carrying conductors look slightly larger than #8. The Ground wire is a #10 and is proper for this cable as it was manufactured to pair with the current carrying conductors. IMO

[@Jzzonem]

@@Giggles_69 it looks like the zip tie should hold both top breakers securely. Maybe I'm misunderstanding your question though.

[@lkennett]

Installed one of these interlock kits for my 10k watt Firman generator. We get frequent power outages in the winter and are on a well that has a 220v pump, no power = no water. Cheap and effective solution.

[@ralphemerson497]

Bought a Generac LP5500 after Hurricane Sandy tore up the east coast several years ago. Do a 20 minute test run each month. The generator has been extremely helpful several times keeping us warm, lit and comfortable during those heavy winter storm power outages l

[@MukYJ]

Our house has an interlock and we power it with a 9kw generator, which is enough to run about 90% of the house. One helpful tip is to go through your panel in advance and mark each circuit that you want to run off the generator when the power goes out. I used different colors of permanent marker and just made a dot next to each breaker: red dots for mandatory circuits (fridges, freezers, and key lights) and green dots for optional circuits (everything else except the oven, dryer, and shop sub-panel). That way you don’t have to think about it in an emergency, just get the generator fired up then start flipping on breakers, red first then green.

[@Vee1on1]

Is that on a 30Amp leg?

[@matthewhuszarik4173]

I have a similar system except I have solar panels with a Power Wall. They is hooked up to a secondary panel with my critical loads. So on a loss of power critical loads are automatically powered and a automatic disconnect isolating these loads from my main panel and the grid. If I choose to supply non critical load or my solar panels can’t keep up with my critical loads I have a NG generator backup that supplies my main panel.

[@woohunter1]

The red and green dots are a great idea, I’m going to steal this idea!

[@jimj9040]

Green is for Go man, and red is for stop. I’d mark them opposite, but the concept is sound.

[@MukYJ]

@@jimj9040 that does make sense but when I first started I didn’t have a green marker 😆

[@ticman1962]

I am using this same setup,this does gives the homeowner much more flexibility to choose what combination to run based on the wattage that is coming in. Most of the newer portable generators 10,000 and above have 50 amp plug in on unit. I have a 12,000 watt rated one and having a 50 amp plug option vs a 30 amp is no comparison. I used Romex 6/3 wiring for 50 amp circuit and a box that is also 50 amp & also had to buy 50 amp breaker and a interlock switch for panel. I have a well pump so when down no water, can run one 220 at a time along with lights and fridge & and outlets. Cant run heat pump but by far having this for backup is a must to keep the home fires burning!

[@backdoor5993]

I appreciate the inspiration! I have been wanting to install a generator outlet for several years. I tried to hire an electrician but nobody was interested. I finally did it myself after watching your post, it took about two hours from start to finish. Disclaimer, I had an old 30 amp breaker for an electric range I wasn't using so the main wiring was pretty simple. I just disconnected the range wiring and reconnected the 30 amp generator outlet to that breaker (plus the ground and neutral wires). I made my own interlock bracket (disclaimer: I have knowledge and access to machining tools (i.e., Bridgeport, bandsaw, etc...) at work) and everything worked perfectly. Thanks for the encouragement to get this off my to-do list!

Did you consider replacing the actual breaker? I have seen corrosion on older panels. It was a good idea to repurpose the breaker position.

[@marlonvite4152]

Tip if you want to try to see if it is better or not: for thick wires drill cable holes on the corners of the wiring box, never in the center of the wiring box and you will benefit of having more space to bend the wires around when you do the connections.

[@kc7154]

To solve this problem, I installed a single pole illuminated switch “on” that is wired before main power hits panel. When power goes off flip switch, when power comes on but main breaker is in off position, switch will illuminate showing power is on. Works great.

Here are the generator safety tips: 1) Please do not allow an unqualified person or your children to operate the portable generator. That is important against the generator safety rules. We also need to be keeping an eye on our children too. You need to make sure that your children are not playing near the portable generator especially when it’s running so they won’t get electrocuted. Generators pose electrical risks and they can be hot during an operation. Please keep your children away from the portable generator at all times. It is important to keep our children safe especially our little ones. Be aware of all the hazards. 2) Some people use their portable generators indoors which increases the risk of carbon monoxide poisoning. It’s important to have a carbon monoxide if you have a gas generator. Never ever use your generator indoors even if your doors and windows are open and even in the garage is not safe to use a portable generator. Not even at your porch and your deck. It is never safe to use your generator indoors and in enclosed areas of your home. Your generator needs to be 15-20 feet away from your house. 3) 🔥generators cause fire hazards too. Never refuel your generator while it’s running. You need to let your generator cool off before refueling it and before storing your generator. Never overload your generator too. Never ever back feed your generator. You should never plug your generator into a wall outlet. Also never store propane tanks indoors. Please keep flammable things away from the generator as well and please don’t smoke cigarettes near the generator. Having a fire extinguisher next to the generator is also important against the generator safety rules. 4) generator operation; make sure your hands are dry before touching the generator. Never use your generator in wet conditions. Don’t let your generator get wet. You need a generator tent if you need to use your generator during wet weather. Please don’t wear loose clothes when operating the generator. Turn on your generator before plugging in appliances. Use the right cord for your generator. Please do not use worn out cords. Hope this helps.

I marked the breakers ahead of time the only ones I want to turn on! Also I set down at my computer and printed out step-by-step instructions on what to do what each of the breakers goes to that I want to turn on and about how much power they use. Most people don't understand what the generator doesn't make power! It changes the power in the fuel into electricity. The more electricity you use the more fuel it uses! Most generators have the best fuel to electricity conversion at about half the rated power for the generator. Try not to use more half the rated power as much as you can. Running it at the top rated power is hard on the generator and burns a lot more fuel! I have learned much of this because of many Hurricanes, and not able to get more fuel because the places that sold fuel didn't have power to sell the fuel. GOOD LUCK! STAY SAFE!

Requires drilling, wiring, and a whole lot more work.

[@keithharrington6181]

I caution all the viewers here to make sure you are using the correct wire size and breakers for your application. Those drop in your ear speakers that plug into your phone have wires that can carry 120v, but use them to power up anything more than a test meter at that voltage and expect the wires to rapidly heat to the point of melting the insulation off and catching fire. Also, the wires need to be captured in the box or installed in piping/tubing to prevent accidentally pulling them out and exposing bare wire to people or flammable material like wood in the wall.

You can always go to a thicker gauge wire but you can limit it with a lower amperage breaker.

With this setup do you have to go outside on the mais and shut it off or does this bypass that?

[@SlightReturn666]

I was really shocked by how much effort it took me to get a reliable system in place. Main steps: 1. Install an inlet on the outside of the house and wire it into a breaker installed in the the top left breaker on your panel. Use suitable heavy gauge, 4-conductor wire. E.g., for a 30amp setup, you'll want at least 10/4. 2. If you don't have an in-panel master cutoff switch for the whole house (I didn't), get one and install it. A little intimidating at first given the huge electrical cables, but dead easy. 3. Install an interlock kit in the panel. 4. Optional but good idea, especially since you already have the panel open: install a whole-house surge protector. Not really needed if you use an inverter generator, but not a bad idea to have anyway. 5. Call the wiring inspector, get the above inspected, and put the inspection sticker on your panel door 6. Choose a good generator. With a construction-type genset in the field, you can get away with Chinese crap. But for home use, you want something that you absolutely KNOW will work when the s&%t hits the fan. I recommend a Honda 120/240 setup. An inverter set, or one of their -SX models, will have THD well within the limits of what you need for delicate electronic gear in the house. See below for why you might want to choose one with electric start. I wouldn't recommend getting an overly large genset for what you need; generators don't "turn down" well and an oversized on will use gobs of fuel. Get one with enough surge headroom to be able start critical systems like your sump pump (again, Hondas generally have tons of headroom). 7. If you are using a simple manual interconnect, or a transfer switch that leaves Neutral connected to the grid in either position, un-bond Neutral from Ground in your genset. Many construction-type generators will have this bond; if so, consult your manual for how to un-bond it. Easy. 7. Strongly consider converting the genset to run on natural gas. NG should be available through the most prolonged blackout, and you'll never need to run to the gasoline station. Slightly fiddly but not hard. 7a. if you did as above, unless you already have a NG connection to run your barbecue, you'll have to sling black pipe and install one. You should seriously consider hiring a pro to do this because gas leaks = no bueno. I did it myself though, so you can too. Call the gas inspector and get the new piping inspected. Put his sticker on it. 7b. If you go the NG route, you will almost certainly need electric start. Pull-start works fine for gasoline but it needs to develop a solid vacuum over a few seconds to start when using NG. 8. You may want to engineer some kind of simple roof to keep the rain and snow off your generator. So much the better if it shields the electrical outlets out of the elements as well. I went to West Marine and got some parts for a Bimini top and made a decent roof for it. 9. Meticulously keep the oil in the genset fresh. Even if it hasn't been run, change oil every 6 months. It's only a quart or so in most generators. 10. If there's any doubt, put a new spark plug and air cleaner element in there. 11. If you're going to operate the genset next to your house, you may want to extend the exhaust. If so, do it with a non-rigid connection such as a silicone hose. An extension may increase back pressure a bit, which will reduce the genset's efficiency a little bit, but to keep exhaust fumes away from your house it's probably worth it. 12. If you are going to use electric start, you really want to connect a Battery Tender to the battery to keep it at 100% at all times. A nice way to do this is, run your Battery Tender wire out to the inlet box you installed in #1 above. It will have a standard SAE 2-pin connector on the end. The inlet box will probably have a couple of knockouts, so you can just run the connector out there. Then it's dead simple to connect your battery and keep it charged up. All in all, it's a lot of steps but having truly bombproof, reliable backup system. It's not fun to be OCD about everything in life, but on a house backup generator setup it's a wise way to roll.

I kinda like the way you've done this, even though its not how i did mine. Mechanical Interlocks are inexpensive today, the one i used is rated at 240v 150 AMP. They have several advantages, they are easy to wire unto generator remotes, so when power is lost a generator can start on its own, the interlock will switch from mains to generator. Its all automatic, they are designed and do fail safe, and there is zero chance of back feeding the grid, or cross connecting the grid to the generator, and because it wires inline to incoming mains, all your existing wiring is perfectly fine for carrying there normal loads, you'll be able to safely run any load including AC and Heaters. A decent interlock, about i don't know an hour of no power to fit it, install the generator cables, and reconnect to the breaker box. Probably do it for £200 and its WAY WAY WAY WAY WAY WAY safer in the long run

Great video! First time seeing your channel. I'm not seeing much difference between using the dryer recep and installing a whole new recep? Other than more money, work, & another hole in my house. If I'm wrong somebody please tell me. I'm new to this, first time homeowner for 8 months now and new firman tri fuel 10k generator. My utility room is in the basement and has a small window above the dryer. The screen already has a hole so...boom. I also have a capped off has line right there also in case I need to run it off natural gas. It cost me $800 to have that dryer recep put in(finished basement and the panel is on the opposite side of the basement). I can't afford another one right now. Single income family of 6. Hoping for some feedback. Thank you have a blessed day.

Here are the generator safety tips: 1) Please do not allow an unqualified person or your children to operate the portable generator. That is important against the generator safety rules. We also need to be keeping an eye on our children too. You need to make sure that your children are not playing near the portable generator especially when it’s running so they won’t get electrocuted. Generators pose electrical risks and they can be hot during an operation. Please keep your children away from the portable generator at all times. It is important to keep our children safe especially our little ones. Be aware of all the hazards. 2) Some people use their portable generators indoors which increases the risk of carbon monoxide poisoning. It’s important to have a carbon monoxide if you have a gas generator. Never ever use your generator indoors even if your doors and windows are open and even in the garage is not safe to use a portable generator. Not even at your porch and your deck. It is never safe to use your generator indoors and in enclosed areas of your home. Your generator needs to be 15-20 feet away from your house. 3) 🔥generators cause fire hazards too. Never refuel your generator while it’s running. You need to let your generator cool off before refueling it and before storing your generator. Never overload your generator too. Never ever back feed your generator. You should never plug your generator into a wall outlet. Also never store propane tanks indoors. Please keep flammable things away from the generator as well and please don’t smoke cigarettes near the generator. Having a fire extinguisher next to the generator is also important against the generator safety rules. 4) generator operation; make sure your hands are dry before touching the generator. Never use your generator in wet conditions. Don’t let your generator get wet. You need a generator tent if you need to use your generator during wet weather. Please don’t wear loose clothes when operating the generator. Turn on your generator before plugging in appliances. Use the right cord for your generator. Please do not use worn out cords. Hope this helps.

I'm thinking only connect to the inside 120v. just want to power essential stuff like freidg. few lights ect. thanks

EZ-connect from Home Depot is a whole home manual transfer switch. It must be wired in between your two phases from your main panel. No limit on the number of circuits. I will agree a kit like this is ideal if it can be used at you have demonstrated in this video.

[@kinglee3990]

Yes, I agree this would be nice if you have a 220 volt generator, but still need to check with your local county code to make sure that this face plate is allowed in your area. Some counties do not allow this because the neutral is not isolated and thus if there is a fire or someone on a pole gets hurt, the homeower/renter or the person that installed it is legally liable.

[@7511fsm]

@@kinglee3990 I'm not sure what you're saying about the neutral not being isolated. The neutral and ground are bonded at my main service panel.

[@terryj.macmullen9968]

my issue here is that the main neutral is still connected on the center tap on the utility pole transformer.could this pose an issue again for those working on the lines? i feel that for total safety against back feeds,the neutral should also be opened when you shut off the main switch to use a generator.instead of a two pole disconnect on the main, what about a four pole switch to totally isolate house from utility by diconnecting neutral and ground?

[@billonthehill9984]

Overall a good presentation & in his disclaimer he did state to hire an electrician if you are not comfortable working inside a panel box, good advice...I didn't particularly like the power inlet box used, it looked flimsy, to much plastic imo. The wires should have been run through a bushing rather than the raw cement wall, I used a scrap piece of 5/8" heater hose on my install & I wired into a Reliance power inlet box that sports a strong sealed spring loaded lid. Since this was a 30 amp system, the wire used should have been a 10-3 Romex, ( 4 wires ) I don't think this was mentioned... I used an almost identical Interlock switch from the same company, they are located in NJ... My box is an older GE 200 amp box & my switch also went into the top LH corner of the cover...In my case, I relocated my top ( 2 ) 15 amp breakers down to bottom LH side of the box. I installed a new single double throw 30 amp GE breaker in their place & wired my Romex 3 into it. The videos ends at this juncture so I'll take a bit further... I run a 50 ft. L14-30 cable over to my Champion, which is approx. a 7 KW portable generator which I run on LPG, i.e. propane...It operates my entire house, ALL CB's remain on...The only thing I don't operate is the electric oven, it is 50 amps...The upper elements work just fine... The 9350 dual/fuel Champion runs a deep well pump, propane fired furnace, TV, computer, all the lights & sometimes simultaneously with ease...Back outside I made a dedicated generator pad & drove a 6 ft. solid copper rod into the ground with the correct grounding clamp as I ground the unit whenever in use, most people ignore it, I don't & all of the manufacturers do recommend it...I'm ( 3 ) years in on this setup with approx. ( 20 ) hours time on the clock. I keep on hand, ( 2 ) 40 lb. tanks & ( 2 ) 20 lb. tanks as they are all portables that quickly & easily hook up to the Champ. I threw the factory LPG hose away, but kept the regulator & reinstalled it onto a 6 ft. commercial grade hose, i.e. soft & flexible...I also maintain a running time journal, whereas typically I will get 18.25 hours out of a single 40 pound tank...This generator will NEVER see gasoline, therefor I will NOT deal with gummed up carburetors from bad gas that goes bad after sitting to long...I did the advance research on my install, got it all done safely & correctly & saved myself a ton of money in the process... Bill on the Hill, Vermont, USA... :~)

[@billonthehill9984]

One other thing I failed to mention on wiring up the power inlet box, I saw no wire lock nut on the backside of the box as I did do this on my install. I chiseled out the wood to accommodate the nut for a flush fit of the box... When the wire is pulled through the box & the length is determined, it is important to LOCK the cable in place whilst you are squeezing the wires into those tight spaces for the hookups...One last thought, if the power inlet box is on a exposed outside wall to all forms of weather, I would use a clear sealant on both sides & the top of the box, leaving the bottom edge open for possible drainage...Professional electricians are more than familiar with the importance of this when working with outside utilities on a residence or commercial work sites... Sometimes it is those little things that can make or break a successful project... Bill on the Hill... :~)

Canadian electrical engineer here. I don't know about USA, but this would be completely unacceptable in Canada. Any interlock that can be defeated by removing a cover or with common tools is not permitted. As the video mentions, this is not only a safety issue for the homeowner, but is also be hazardous to line crews working to restore power. It should also be mentioned that even with the main breaker turned off the line-side terminals are live. Again, in Canada, it would not be permitted to pass the branch circuit wiring through the service entrance breaker space. If you are in the USA, you do you and comply with your local codes, but at least be careful with that main breaker.

[@daveperez3557]

My dad wired into his house with a generator. He messed up the wiring diagram. ended up putting 240v on half of the house wiring and 0 on the other half. He's spent about $1,000 replacing spark fault interrupter circuits, still not sure why he put them in every single room in his house. The only lesson I have for you here is to pay attention to wiring diagram, and if you can, test something with a voltmeter before you ever connect to anything you really care about

According to the national electric code arc fault circuit breakers are required on all circuits in house with a few exceptions! That's most likely why he would have installed them!

Your panel neutral is still connected to the outside. If there is a issue like power comes back on the neutral your generator will go boom or you have a short on your house with the generator power could be sent back via neutral to the plant and you could kill a power company line person. In other words you could backfeed neutral....

[@REWYRED]

Not possible to back feed a neutral how you explain, especially when its bonded off to ground.. Many large back up generators are configured in basically the same fashion, the transfer switch interrupts only the hot conductors but the neutrals from generator and utility remain connected together along with the load neutral at all times.

[@dienekes4364]

I've been wondering if you can couple something like this with solar panels. Would the generator provide the correct power frequency to allow a tie-in inverter to provide power and would that cause too much back-feed into the generator? Could you use a diode or something to prevent that back-feed to the generator?

[@antibodyarmy]

for adding solar the correct way its basically a generator interlock with added steps. you need a transfer panel to transfer the loads off the main circuit breaker onto a separate breaker that is supplied by your solar setups inverter without a tie to ground like your main panel has. you would never want to have more than one power generator source working at once without the proper panels, switches and lockouts in place. Like he states in the video this lockout prevents power feeding back into the grid, or from the grid to the generator, the same principals apply with solar and gas generation working in tandem. with a lot of solar stuff its worth consulting an electrician. the main reason for this is solar systems arent really ground tie friendly since that creates a ground loop, and that can devastate a solar system. the dc system of solar has its own ground when connected with batteries, when you bring in the ground rod that is attached to your house it at best has some funky flutters in power, at worst burns out all your solar. can you technically hookup a solar backup system in the same manner as a gas generator, yes in fact you can have your inverter hook up to a similar interlock like this. but if something goes wrong its more expensive to replace the solar equipment and batteries than a generator. everything also depends on local regulations, for the most part isolated solar circuts are treated in a way where if you wire it like a DC system like in a car or RV. when connected to something that is connected to a grid things get more complex. if you want to run solar and a gas generator to power more stuff at once, get an electrician to setup your box so the solar is powering all the essentials like lights and fridge, sump pump etc on its transfer panel. and the generator runs its devices, say Air conditioning on another sub panel or if possible on its interlock of the main panel. check out davidpoz, or Will Prowse while they aren't necessarily experts, both of them are decent at explaining solar systems.

[@dienekes4364]

@@antibodyarmy Thanks for the response, but you didn't really answer the question I was asking. If someone has a grid-tie system with a generator rather than batteries, when the power goes out, can the system be configured so that the solar produces power based on the frequencies that the generator produces? This has nothing to do with the method of disconnection from the grid. We're past that obvious point (this can be done through a manual switchover, as shown in this video, or through a smart inverter system). When someone setups up a grid-tie system with battery backup, it can be configured so that the panels generate power based on the battery-supplied frequency. The question is, can the same thing work with a generator?

[@ShelbyvsViper]

@@dienekes4364 Should be able to. A generator depending on what type, should put out 60 hertz (+ - 5 hertz). Grid power is 60 hertz on the button. The frequency tolerance is 5% so 57-63hz is the range. You want to start with about 62hz at no load because it will drop a bit as the engine is loaded up. Voltage is the same deal. If your generator has a voltage adjustment then set it for 125 volts at no load. It will drop some as the generator load is increased.

Great job! It is a pleasure to see someone show the correct and safe way to hook up a genny to run most of a house during a blackout. I would just add - most municipalities will require that you pull a permit for this work, and have it inspected once complete. I can't stress enough the importance of this. If you do not pull a permit and your house burns down from an electrical fire - even if the fire was not caused by your work - your insurance company will likely not pay the claim without a long, expensive legal battle. Pulling a permit is great (and low cost) way to have an expert double-check your work for you.
