changing a 220 outlet to 110?
I have removed a small built-in oven that was powered by 220. The feed consists of 4-wires. the GREEN is 12 ga., & the RED, WHITE, & BLACK are 10 ga. I would like to replace the circuit breaker with a single 110v 20 amp, and my question is, WHICH WIRES DO I USE, and which one will NOT be used? I know the GREEN is my ground.
At present the breaker is wired with the RED, & BLACK, and the WHITE is hooked to a bar above. Of course the GREEN is hooked to the ground bar.
Thanks,
Dale

Use either the black or the red as the hot wire. The white will remain as it is now, the neutral. Cap the wire you do not use on both ends and tuck it out of the way.

One more note. The 10 gage wires may not fit under the screw terminals on the receptacle. If they do not fit, then use 12 gage pigtails to make the connections.

Just use a section of 12 ga. and wire nut to the 10? I have always wrapped tape around the wire nut to aid in preventing such from backing off, is that a good thing to do?

On the oven end, install a two-gang box and 2 GFCI’s.
- Using a wire nut connect 2 white wires (12-gauge, 6-inch long) to the white wire from breaker panel.
- Connect one of the white wires to each GFCI’s neutral line input.
- Connect the red wire to one GFCI’s line input and the black wire to the other GFCI’s line input.
- Pigtail grounds to each GFCI.
Use the deepest box you can get because it is hard to fit two GFCI’s in the box with 12-gauge wire. Don’t run the white wires from one GFCI to the other; you must pigtail from the source white wire. You can use 15amp GFCI’s but they wont accept a 20amp appliance plug.

Very few appliances have 20 amp cord and plugs or require a 20 amp circuit.
I did not suggest two circuits because this would be a multi-wire circuit. Multi-wire circuits have very specific rules and requirements, and are not for novices.

This 110 outlet is going to be used for a on the counter microwave. I have a couple more outlets in the area, so one is all I need at present.
