We've had some issues over the past few years with GFCI and AFC/GFCI combo breakers being installed for condo remodels in buildings that have a 208y/120 system. What we found was that the 120/240 rated OCPD (double pole GFCI) will not work in the 208y system. Most often, the OCPD won't even trip with the self-test button. I am starting to see spec sheets from Schneider, for example, that now clearly list a 208y as an option for their double pole breakers.
This was a big issue for a while. Does anyone have any more recent experience with this?
Specifically, during a condo remodel, the existing dishwasher/disposal circuit was originally run in conduit using a MWBC so we highly recommend they pull another neutral to eliminate this problem when they have to add an AFCI/GFCI combo. Neither will trip and I am told it is because of the 208 voltage. I think we need some more light shed on this.
