How to install a 220 volt outlet

Installing a new 220 outlet isn’t much different from a 120-volt outlet. However, you can only put one 220 outlet per breaker/circuit. And you will install two hot leads to the outlet and not use 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.

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.

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


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… Read more »

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


Dominik 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… Read more »
