12 /2 and 14 / 2 in Junction box
I noticed a junction box in the basement that has 12 /2 armored cable coming out (opposite feed end) and 14 / 2 going in. I plan to add lighting fixtures on this circuit. Should I change it all over to 12 / 2? Thanks for your advice, Tom
You should check the breaker size that feeds this circuit. If it is 20 amp, all the wire on the circuit needs to be at least 12 gauge. If the breaker is 15 amp, #14 wire is OK.
