Looking at a commercial grill, its a 3 phase 12kw 208 cooking unit says the name plate and spec. sheet. Looking at the specs it calls for a MINIUMUM of a #6 copper for the supply (on at least 2 of the phases, the 3rd phase you can use minimum of #8). When I did the math, I came up with
12,000/(208*1.73)=33.35 amps
which means that #8 copper should work for all 3 phases. But like I said, it calls for A phase=#6 copper, B phase=#6 copper, C phase=#8 copper.
Also on the spec. sheets it shows 38.2 amps on A phase, 38.2 on B phase, and 25 amps on C phase. I thought that was odd since the nomeclature shows it as a 12kw 208 3 phase cooking unit. Not sure where the extra amps comming from. And no, its not a continous load. Am I missing something here?? Thanks for the help.
