Hello,
Context: Midwest United States single family home built in the early 1960s.
Situation: We are remodeling our main bathroom and installing recessed lights above the tub. I understand that anything - not just receptacles - within 6' of the tub or sink needs GFI/GFCI protection. The current strategy is to put a blank-faced GFCI device somewhere on the wall (inconspicuously-ish) that will feed the lights.
Potential issue: The lighting circuit is 15A using 14/2 NM cable. However, it seems most of the blank-faced GFCI devices that I am finding for sale are 20A.
Question: would it be legal/conformant to code to use a 20A blank GFCI device on a 15A circuit and upstream of only 15A loads? There will be no receptacles downstream of the GFCI, so it's not like anyone can simply plug anything in or modify the load without tearing up the walls or something like that.
I've tried researching this a bit but haven't found a satisfactory answer yet.
Thanks!
