I don't know where the prior answer gets his numbers (if 0 gauge he means 1/0, it and the 4 can go higher). The rules for wire size and breaker size are complicated, and there are exceptions, but here is a rule of thumb. It is valid for no more than 3 current carrying conductors in the cable or raceway, and an ambient temperature of 86 degrees F. Some wire types and some applications can have a larger breaker than this.
14AWG - 15 A
12AWG - 20 A
10AWG - 30 A
8 AWG - 40 A
6 AWG - 50 A
4 AWG - 70 A
3 AWG - 80 A
2 AWG - 90 A
1 AWG - 110 A
1/0 AWG - 125 A
This is all for copper wires only.

I've never heard of a 220 amp panel. That makes me wonder about your electrical abilities. There is no code restriction to keep you from using number 14 in the garage or anywhere else. Unless it is a local code. Your 80% figure only applies to continuous loads like heaters and motors. Not to general use outlets. You can use all 15 amps on each circuit. I see no problem at all with what you are trying to do with the 14 wire and 15 amp breakers.

30 Amp Breaker Wire Size
2016-10-17 01:58:31 · answer #5 · answered by freer 4 · 0⤊ 0⤋
I prefer to use breakers smaller than the capacity of the conductor, example 12awg conductor 15 amp breaker. It's overkill but I like the additional safety factor. Most residences have outlets only rated at 15 amp but I won't use smaller than 12 awg, with the exception of dedicated lighting circutswith very low total amp load.

14-Gauge wire should be connected to a 15-Amp breaker. 12-Gauge wire should be connected to a 20-Amp breaker. 10-Gauge wire should be connected to a 30-Amp breaker. 8-Gauge wire should be connected to a 40-Amp breaker. 6-Gauge wire should be connected to a 50-Amp breaker. 4-Gauge wire should be connected to a 60-Amp breaker. And 1/0-Gauge wire should be connected to a 100-Amp breaker.
I recommend using no wire smaller than 12-gauge and keeping the smallest breaker at 20 Amps.
