Need some advice. I've got bedroom outlets that are wired using 14/3 romex. When I replaced the regular two pole breaker with a 2-pole arch fault,the circuit fed by the red wire trips the arch fault. When I dissconnet the branch circuit from the homerun, breaker holds. Both circuits have lights and outlets combined. This is my first dealing with arch fault. I want to know if there are certain devices that cannot be protected by an arch fault breaker. Any advice would be appriciated. Thanks
