What do you do with the neutral wire of a 14/3 romex when the two hot wires are circuits for the bedrooms?
I bought four Fault Protectin Breakers for my four bedroom circuits but when I went to install them I noticed they were run with 14/3.
Each Fault Protection Breaker has a neutral pig tail built into it to land in the neutral buss bar. You are suppose to take the neutral from the homerun directly to the breaker neutral terminal.
You need to find the Cutler Hammer arc fault breaker specifically made for multiwire circuits. Otherwise, you'll have to redo the circuit with 2 homeruns.
