Greetings,
I'm caught between an engineer, equipment manufacturer. The existing (under-sized) ckt was contractor installed and passed by L&I. The original spec called for a 60A ckt. Apparently a field modification was requested and granted...which has resulted in significant head & rump scratching seasoned with some veiled finger pointing.
The DW nameplate lists 49A @208V-3ph. Although it's UL listed there is no published mocp value on the nameplate and the mfr would not supply a value to the engineer.
I'm thinking a 70A breaker (#4Cu) would suffice but the engineer is calling for an 80A breaker. 12Kw of the 49A is a booster heater. Thoughts?
