How to install a 220 volt outlet.

Watch this video on YouTube.

Installing a new 220 outlet isn’t much different than a 120 volt outlet. However you can only put one 220 outlet per breaker / circuit. And you will installing two hot leads to the outlet and not using a neutral for this type of outlet in the video.


In the below diagram you will notice that for a 220 volt outlet you would need a two pole breaker. What this means is that the breaker will take the power from the panel by the two very different phases. Each one is 110 volts. Combined you have your 220 volts. However you will still need a ground as you can see. Some need a neutral as well. Most of the time these would be things like your stove. But for now this pretty much covers a simple 15 or 20 amp 220 volts.

The wiring needed for this type of insulation you would use 12/2 wire for a 20 amp installation.

If you’re looking for instructions on how to install a 4 wire 220 outlet see this video 


The red wire is really just red for the picture. If you’re using a 12/2 wire you would simply just use the white and the black wires to power the outlet and the bare copper for the ground that I show here in brown. Don’t think you can just use two separate breakers. It just doesn’t work that way.


Important: This setup is does not use a natural wire. A natural wire is a return path back to the transformer in other words a balanced. More reason why you can’t add more then one 220 outlet per breaker. And this is considered a two wire setup. Look for are four wire setup also has a good reference on 220 outlets

    Dominick thanks for the video. I always wanted to know how to do that. Now I know. THANKS Again. Also I learned how to clean my oil burner. Good health to you.

  2. How many feet do 220 outlets have to be from each other?…reason…..I’m building a house and want to run my washer and dryer in the kitchen……(I have a huge kitchen.) But I have a oven on the wall that has the only space were I can put the washer and dryer. Can I run 2 220s side by side say within 5 ft..?
    And should I separate the two with the washer?


  3. I have a problem. I’m Installing a new Range into a Commerical Factory in the break room. We get 480 Volts into the place and then have a number of transformers to change the voltage to what it needs to be. So I’m tapping into the 120/240 volt panel. There’s no Common block only Ground, so I ran #8, 3 wires, Red, Black and green to the break Room and to a new Outlet. What a hassle.

    Now at the new Outlet I get 126v from L1 to ground and 145V from L2 and Ground and around 240 from L1 to L2. The problem is when I go and plug in the new Range, it doesn’t work?!?!?! So I measure voltage at the end of the plug at the range and Now I read like 220 Volts from L1 to ground, and 13 volts from L2 to ground?!?!?! Why would this be? I would think that I should still be reading 120 or so volts from L1 to ground and L2 to ground like before. The Range is off. I’m not getting any Clock on the Display, but if a turn the Stove top on I start getting heat.

    Is this some type of wiring issue?!?! Is the new Range screwed up? That seems unlikely, but I guess you never know. I ran around 210 feet of wire though new conduit that I had to run for this project. Any Ideas what’s going on?

    • You ran two hots and a ground. But why didn’t you run a neutral ? I don’t know what a common block is. It’s either a ground buss bar or a neutral buss bar. When you’re dealing with 220 volts a neutral is even that more important.

  4. I need help with some electrical questions.
    I have small appliances from Japan (100V, 50-60Hz), washer/dryer from Korea (220V, 60Hz) and oven/microwave oven from Malaysia (220-240V, 50Hz, 6.6-6.0A). The Korean plug has 2 round prongs and the Malaysian 3 large flat prongs (British style).
    1- Is it possible to have a house in the US wired with 100V and 220V outlets?
    2- If so, would any electrician be able to do it?
    3- Would it be safe to plug the 50Hz oven in a 220V 60Hz outlet?
    Thank you.

    • Hi how are you. To be completely honest with you I don’t know. Yes you can have 220 volt outlets in your house. But 100 volts ? That seems low. Did you mean 120 ?

      • Thanks for the prompt reply.
        Yes, 100V. In Japan the electrical grid is set to 100V. There are 2 frequencies 60 Hz in the West and 50Hz in the East. I wonder if there is a long term problem if I plug the Japanese appliances into a 120V outlet…

  5. hi, I have installed a 220v 20amp outlet like the one in the video. I plan to use equipment purchased in China, do you know if there is an adapter that will let me plug a chinese connector into that outlet?


    • I don’t know of any but I’m sure they make them. however it would be much better and easier to just replace the plug. But make sure what you’re getting is the right Htz. and phase we have here in the USA. If you send me a link to it I’ll be more than happy to look at it for you.

  6. I have 110 in the house, I have 110 in the garage which is hooked up to house panel also have panel in garage, would like to have 220 outlet in garage to run 220 heater. any suggestion would be appreciated thank you

    • If you have a sub panel in the garage you should be able to pull the 220 from there. You would have to see if there is two hot legs in the panel and you really should have that.

  7. We bought a used hot tub, we have 110 already the guy we got it from recommends 240, how do we go about changing? We have a new breaker box.

    K, going to add a 220 volt outlet in my garage for an air compressor, the compressor requires 20 amp. The question:

    I already have 110 electric in the garage that runs the lights and a couple of outlets. Instead of having to pull 3 new wires (2 hot & 1 ground) for the 220V outlet, can pull just one wire for the additional 110V I’ll need and utilize the existing 110V wire (and ground) for the second hot to the 220V outlet?

    The reason I ask is because I can run one wire through the existing conduit, Thanks.

  9. Jonathan Calender says:

    hi great video.what happens if you want to install a 220 outlet and there isnt any room in the circuit box for you to wire in another 220?thanks*

    • You would install a sub panel. Follow the link if you see one here. Or look in electrical on the main menu on top.

  10. Dominick. Great info and fun to watch video. You told me all I need for next step and saved me time and money. Hot tub awaits!

  11. Great video. I think it would be wise to tape your "white" wire using "black" tape so that everyone would know that this is a "hot" wire.

  12. Very good. Thank you so much for your info on this.

  13. I notice you put the ground pin on the bottom. I think the code is gradually changing to require it on top. That way, should a metal object like a thin picture frame fall between the outlet and a partially inserted plug, the ground pin serves to deflect the object so you don't get a short. Of course, many 220 plugs are right-angle style, and would be upside down if you put in the plug that way. So "whattaya gonna do."

    I enjoyed the style of your helpful video. Thank you.

  14. Yes and no. The same if it's a older dryer. However some newer dryers require three wire the extra being a neutral.

  15. Is this the same process for a 220 Dryer outlet?

  16. Sorry I had to make a new one. But here you go.

  17. Would you put the video back? Tks!
