GFI for shower lighting?


Hi guys,

I'm helping my mother in law do some renos at her new house and right now we're tackling the bathroom. Her interior designer made an electrical plan for me. On the plan it shows 6 pot lights, one of which will be GFI protected ( the one inside the shower stall)

I've had people tell me that the GFI will be constantly tripping from humidity if i do that. so......to GFI protect or not to GFI protect?

You can if you want, but you don't have to.

Not a code requirement for GFCI. A recessed can in a shower requires a shower trim which shoulde seal the fixture from humidity.

Some (perhaps even "many" or "most") shower fixtures say to use a GFCI in the instructions. If it says to, then you must by code. I would not be very comfortable without it. Humidity will NOT cause nuisance tripping. If it trips from humidity, it's protecting you from a dangerous problem.

EDIT: I poked around online, and it looks like most do not require GFCI protection. I had installed two types that did, and seen one other that did, but it seems those are in the minority.

For real?

Change "Some (perhaps even "many" or "most")" to "almost no".....

I have NEVER seen a typical shower trim that required GFI protection.


Now a bath fan, that is a different story....
