I've been reading up on NEC 2023 - and possibly misunderstanding, and the 2023 doesn't apply to my area anyway (...yet). My current reading of 210.12 suggests that NO 240v circuits require AFCI: is this correct?
That said, I'm contemplating a few possible electrical designs right now, probably going over the top. If I DO want to implement both AFCI and GFCI protection on a 240V 50A circuit (such as for a range or a clothes dryer), what are my options?
I can't find any combination-function breakers that are 240V, much less high enough current.
I can't find any GFCI outlets for 240V.
Could I get deadfronts for AFCI and another for GFCI prior to the receptacle? If it exists, a deadfront GFCI might be cheaper than the GFCI breaker - and I will need at least GFCI.
Maybe this is a moot point given the code doesn't require this, but I'm trying to learn and want to see what options exist.
(As a side note: my reading of (2023) 210.12.A.4 suggests that a listed AFCI outlet is fine (and protecting downstream outlets?) if the breaker is listed and the run to the outlet is continuous (unspliced) and 50ft or less for 14AWG or 70ft or less for 12AWG, assuming you label the outlet. Not sure where I can get the list of what qualifies for 210.12.A.4.d, though - can somebody correct or clarify? If this is the case, what's the point of the the metal sheathing described in 210.12.A.5?
