4 Wire Outlet
If you were installing a four wire 220 outlet chances are it’s for a stove/oven. Now, this could be either 40 or 50 amp. So either #6 or # 8 wire. These wires are a lot harder to handle and thread through the walls and ceilings and generally cost a lot more than your normal 12 and 14 wires. So make sure you have enough to work with because making the bends and turns you’because making more to make those turns. You won’t be able to bend it into a 90 degree like you would the thinner wires so the result is using more of it to go the same distance. I can’t tell you how many times I ran only inches short.
They do make a small hand tool to help make the bends for thick wires. Since I can never find when I need it I sometimes use a short 2″ pipe over the wire to help with the bending process.
You will be using a two pole 40 or 50 amp breaker. Just to be clear. I don’t mean two separate breakers next to each other but one complete breaker where the trip lever on it is one. So less it looks like two breakers glued to each other. So each side of the breaker is actually getting power from the two very separate buss bars. Each one of those is 110 volts. Resulting in simple math 110 + 110 = 220 volts.
The Neutral Wire.
Sure you can run a 220 line without the neutral, but not for this type of setup. Many new appliances require the neutral wire. Most believe the neutral is the ground. However not true at all. The neutral would be used as a return path for the 110 volts needed by things like the clock in your stove, timers and, of course, the computers/controllers in most newer appliances sold today. So, in short, your new stove uses 110 and 220 volts. 110 for the smaller stuff and 220 for the cooking elements. Or dryer whatever it is that you may be hooking up.
