I'm wiring up 2 bathrooms and have all the receptacles on dedicated circuits. However, I'm thinking of wiring the lights and fans for both bathrooms on the same GFI breaker. Anyone know if this OK? The lights and fans draw a pretty light load, about 900 watts.

You have two options for bathrooms under the NEC.

1. One circuit that ONLY feeds bathroom receptacles. It can feed them in one or more bathrooms. The lighting and fan can be on anyother circuits.

2. One circuit for each bathroom. In that case the circuit can feed the both the receptacles and the lights and fan, but only in that one bathroom.

In either case the circuit(s) that the receptacles are on have to be 20 amp. If the lights and fan or a different circuit they can be on 15 amp circuits.

Also, in general the light and fan don't have to be GFCI protected. And in if they are it is best not to use a GFCI breaker. Using a GFCI breaker will cause the lights to go off if you trip the GFCI.

Some fans are required by the manufactor to be GFCI protected if they are installed over the tub/show. Otherwise not. But look at the instructions for the units that you are using.
