14/2 Guage wire back to 20A breaker
My electrician is finishing the 'rough-in' work for our kitchen renovation and I was surprized to see the lighting setup.
He is taking a feed from a new 20A circuit breaker. I am not sure what guage the wire is coming from the breaker as it is in BX/armored cable. However at the first junction box it is split into 12/2 cable feeding some outlets and 14/2 cable feeding the lights.
Is this a problem? I always thought you could only use a 15A breaker if anywhere along the route a 14/2 cable was used. I want to ask him but he's left for the day and would like some advice before I see him tomorrow.
