I have two exhaust fans in restrooms, two inline exhaust fans in duct all four on 120V single phase fed from one branch circuit. The branch circuit is 0.39kVA which equals 3.25A.
One inline is model Cook GN520 and second inline is model Cook GN320. The two restroom exhaust fans are Cook GC240, GC220.
The branch circuit breaker provided is 20A. When asked for 15A breaker instead of 20A breaker because load draws 3.25A, I was told that the breaker protects the branch circuit cable not the fan or it’s motors and #12 AWG size cable is provided so 15A breaker would not be provided.
However, I researched but I cannot find the above in code NEC 2014 that branch breaker protects the cable not the fans. Anyone know where it would be for four exhaust fans or the breaker needs to be sized 15A?
