The EMCO spec also says the connection load is 10KVA (Doesn't 10HP = 10KVA?). So is a AD10 sufficient or should it be sized up? If so the AD15 *should* suffice. The AD20 is only $80 more, which is a total load of 20HP or 20KVA? Am I answering my question or am I missing something. If I should upsize the RPC, is there any penalty in going to the AD20? Any of you running them on an AD10 or equiv RPC? Thanks!
