Bathroom lights shared with 20 amp GFCI
After reading through hundreds of posts looking for some help with my scenario I have learned a lot but not quite enough to get my question answered so here it is!
I am building out a new bathroom in a basement reno and need some clarity on the electrical. For any local code implications, I am in Toronto / Canada.
I have run 12/2 on a 20 amp breaker from the service panel to a GFCI and would like to know if I can run 14/2 on the load side to a switch then 14/2 to a recessed light in the shower then on to the vanity light. There will also be a main light on a separate switch fed from the panel on a 15amp 14/2 and shared with receptacles in an adjacent room.
Basically I'm wondering if the 2 lights that would typically pull 1-2 amps only can run on a 20 amp circuit after the last (only) 20 amp device. Does the entire branch circuit and every device (switch, light fixture, receptacle) on it need to be rated for 20 amps or only the portion of the circuit that could potentially pull that much current? I have read that the code supports 15 amp receptacles on 20 amp branch circuits because they wouldn't be able to pull 20 amps.
One other point of clarity I'll add... Does how the devices are wired have any impact on this (passthrough vs pigtail)?
Any help would be appreciated!! Thanks
