More than one 40 amp receptacle on a 50 amp circuit?
Don't you have to use 50A receptacles for 40A or 45A circuits? NEMA does not list any 40A receptacles that I know of.
I think that you're right.
Yep got my wire crossed up again, the table allows for a 40 amp circuit a 40 or 50 amp receptacle and for a 45-50 amp circuit it would require a 50 amp receptacle but 210.21(B)(3) and the table is for where two or more receptacles are installed and is why 15 amp receptacles are allowed on a 20 amp circuit in the table, probably what I had my mind wrapped around when I made my post last night.
Guess I was thinking since 15 amp receptacle are allowed on 20 amp circuits when two or more receptacles are installed on it, then this must also be true for 40 amp receptacle on a 50 amp circuit, e'rrr at least my mind thought so :roll:
It is kind of goofy that they switched this around with these two circuit sizes? while most times a 50 amp circuit will be for cooking appliances but there are applications in a dwelling that also use 50 amp circuits like air compressors, hot tubs, saunas, and welders for which we know we can have multiple receptacles, but since NEMA doesn't list a 40 amp receptacle its kind of a mute point.
