15 Amp Gfci Breaker Wiring Diagram. A 15 amp circuit is usually used for wall receptacle outlets and room light fixtures. Circuits rated for 20 amps must have 12-gauge or larger circuit wiring and must be protected by a 20-amp breaker.
Wiring a Two Poles GFCI Circuit Breaker. The 142 awg cable for this circuit includes 2 conductors and 1 ground wire. These outlets are commonly 15 Amp-125 Volt Receptacle 20 Amp-125 Volt Feed-Through.
GFCI circuit breakers last longer than GFCI outlets and are a good idea if you do not test your GFCI outlets on a regular basis.
An initial take a look at a circuit layout might be complicated however if you can check out a subway map you can read schematics. This wiring is commonly used in a 20 amp kitchen circuit where two appliance feeds are needed such as for a refrigerator and a microwave in the same location. An initial take a look at a circuit layout might be complicated however if you can check out a subway map you can read schematics. This wiring diagram illustrates installing a 15 amp circuit breaker for a 120 volt branch circuit.
