Working on 3 bathrooms apartments and trying to get clarification
In each bathroom I have 1 countertop outlet, a vanity light and a ceiling lights
According to NEC 210.11, I can share a circuit for all 3 bathrooms since I only have countertop outlets. However, am I allowed to share the same circuit to power the light fixtures in the same bathrooms?
It appears that NEC 210.23 specifies serving only receptacles.
Or I should have separate circuit for each bathroom to put light fixtures and countertop receptacle to the same circuit ?
 
You can use a separate circuit for each bathroom or share all of the bathroom receptacles on a circuit and use another circuit for the lighting.
 
I agree with Rob, but I will say it a different way.

If a circuit feeds a receptacle in each of two bathrooms, then it can also feed other bathroom receptacles, but can't feed anything other than bathroom receptacles.

If a circuit feeds a receptacle and something else (e.g., a light) in the same bathroom, then it can feed any other load in that same bathroom (up tp its load limit), but it can't feed anything outside that bathroom.
