Yes this a new circuit
I’m using version 2020 nec
Yes I’m asking about ocpd (over current protection device)/ breaker. Do they need to be gfci protected or arc fault protected like every other circuit in a house.
Risidential? Outside to my knowledge if ceiling is not an open air(no roof), then no special requirements for GFCI. But AFCI, here is where there is arguements. Some inspectors say if the switch is in an area that is listed as requiring AFCI protection then those outside lighting circuit has to have AFCI, claims that the switch is a "devices" per 210.12(A). (And look at Article 100 definitions of device). Others will disagree and say nothing needed for outside spaces. So where is your switch?
From my reading of 210.12(A) (NEC 2017) if the switch (a device) is by your door in a space listed you must provide AFCI protection. If you put the switch outside on porch it would appear to be a "get around", but then depending on exposure might need a wheather tight or inuse cover. This exception for AFCI doesn't make sense to me in that the wireing and enclosure is in the same wall just exposed on opposite side so to me poses the same risks, same for a bathroom that does not require and AFCI protection but the wires for bath run thru same space as other wireing that must have AFCI due to the location. (Ie. Bedroom wall receptacle adjacent to bath must be AFCI but the receptacle in bath that might even be back to back with the one in bedroom doesn't need it.) Don't get it.
