How to install a 220 volt outlet

Installing a 220-volt outlet isn’t all that hard at all. Following the instructions in my video and you’ll be fine.

A big misconception is that you can only install one 220 volt device/outlet per circuit/breaker. Although you’ll better off for every 220 devices/outlet having it on its own breaker.

So here’s the deal on installing more than one per circuit. It’s all math by the way, oh yeah, and lots more money. If you have 2 220 outlets and each one is 20 amps. You’ll need to use #8 wire for the whole circuit including a 40 amp breaker. Now just the wire alone is going to cost you. So yes you can, but do you really want to?

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.

This setup does not use a neutral wire. The neutral wire is a return path back to the transformer, in other words, a balanced. More reason why you can’t add more than one 220 outlets per breaker. And this is considered a two-wire setup.

  1. Awesome, glad I could help you out. Happy New Year.

  2. Great video. Really nicely explained and entertaining. I’ll be installing a 220 plug for a welder in the next couple weeks. Thanks.

  3. Loved the video, but I still have a question about a 3 prong dryer. For years I had no problems until one day wham the dryer would not start. I have tried, on 3 different machines and one of those was new out of the box, to use a dryer in my house after this. The outlet is new and a new 30 breaker also, yet any machine plugged in is only getting partial power. Voltmeter has 120 on each side, but still no joy. Could the line from the breaker to the outlet cause this? That is the only thing I can think of right now.

  4. 10/3 wire is fine. But watch my videos on how to do it.

  5. Sorry, but NJ is a little far for me.

  6. I have recently moved and I have a Jacuzzi that’s run on1 110v . Buy 220v it heat in an hour I’m in Edison NJ and want a price on putting the 220 box in and if you’re prices are responsible I also have other electrical work that needs to be done call me when you can at 917 348 0355 Wooding Ave Edison NJ

    I have a question about running a 220 v 30 amp line, breaker , and 3 prong plug to a 18,000 btu window unit. I have removed some unused breakers from my panel to create space for 2 new 30 amp breakers to create the 220 volts of power. I’m not sure what wire to use (bought 10/2 and 10/3). Can you please advise me on what wire to use and how to wire it to the breaker? I have free space on my neutral bus bar and ground bus bar as well. As in like which color wires go where. Obviously in know which one the ground is but not sure on the other configurations. Mainly the 3 prong plug required on the unit is confusing me on what wire to use and how to hook it up to the breaker panel. Any help would be a huge help. Thanks so much!

  8. i want a 19DC volt power supply which takes 220 AC
    Any circuit diagram ?

  9. mini breakers are for 110. You’ll either have to install a sub panel or move some breakers around. For 220 you’ll need to grab both hot legs.

  10. Thanks for this Dominick. Very helpful. I wanted to ask. I have one slot left in my box but need to run a 220 for an air conditioner. I saw you can buy a 1 inch 2 pole 220 v 20 amp breaker that just takes up one slot in the box and not 2 like the one you showed here. Do you think this 1 inch think 2 pole would be alright?

  11. You’ll have to be more detailed in your question.

  12. Could I pull to 120 volt wires from a solar-powered DC to AC 120v inverter and combine those two Hots onto a single 2 pole breaker in a subpanel to get 240 volts?

  13. Awesome, always glad to hear I helped someone. Merry Christmas.

  14. Great video and very informative. You saved me a good chunk of change. I ran the line, connected the receptacle, grounded the line in the box then put in the circuit without incident. Thanks a lot brother!

  15. Well I don’t know anyone in your area. But the place way to find someone is to ask a friend or neighbor maybe.

  16. Thanks for the video. I need to add a 220 outlit to my garage for a kiln. My late husband was an electrician so I have a little knowledge. But I like the hint of getting it all ready and have an electrician hooking it up. I probley can hook it up, but I rather be safe.
    Oh and the hint of wrapping the outlit, thanks. I am replacing several outlits in my home, I usually turn the power off before I remove one, but I like this hint.
    Thanks again
    ( so how do I find a reasonable , good electrician in Riverside County, California?)

  17. Very informative. I’m reassured that I’m doing it correctly. However I thought it was a neutral wire not a natural wire. At least you did not say brass to save your axe.

  18. Sure you can. Just do it with a junction box.

    Hey I need to run a 220 dyer wire another 20 ft. can I add to the wire to make it reach

    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.

  21. You can put them anywhere you want. For 220 there is not min. But each one has to have it’s own breaker.

  22. 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?


  23. 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.

  24. 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?

  25. One way to find out, LOL.. 100v I never knew that. I in the UK it’s all 220v 50Hz. I’m sure you can get a reducer but it won’t be cheap.

  26. 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…

  27. 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 ?

  28. 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.

  29. 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.

  30. 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?


  31. 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.

  32. 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

  33. All hot tubs needs 220 volts. Follow my video on how to install 220 volts but with the right amperage.

  34. 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.

  35. Thank you very much.

  36. No way. You must run a whole new wire just for the new 220 outlet.

  37. 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.

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

    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*

  40. 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!

  41. 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.

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

  43. 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.

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

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

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

  47. Would you put the video back? Tks!
