Re: Different Gauges of Wire
Although 12 ga. is rated at 20 amps, if any of the other wiring is 14 ga. the breaker for the circuit must be maintained at 15 amp. You can always use larger wire in a circuit but fusing or breakers have to match the smallest wiring used in the circuit. And if you use larger wire do not use the stab connections, connect the wires to the screws. This is a prefered practice even if you are using the right size wires.
