I would like to know if code allows running 1-20 amp circuit to more than one bathroom.
I have a 1/2 bath on the main floor on one 20amp ckt (GFI outlet, light, and fan). I am finishing a basement bathroom which would have a GFI outlet, light, and fan/light. Can I run wiring from the same breaker to this new bathroom? The books I have on this topic are not clear if code allows this. Thanks.
This depends on what code cycle your books came from. This has changed a bit over the years.
Bottom line is if the circuit is feeding just receptacles, you can share it between different baths.
If the circuit has lighting, fans, etc, then it must be isolated to just that one bathroom.
Sometimes I feel like if I answer any more questions it is like someone trying to climb over a fence to jump off a bridge and me giving them a boost.
Answers based on the 2008 & 2011 NEC.
In todays code, the bathroom circuit can feed all bath outlets, not including lights, or it can supply everything in one bath.
The best thing to do is supply your new bath with a new 20 amp citcuit and feed lights and fans fron there.
