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.

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.
