I feel that MarkP gave the correct code reference. 210.23 -'02 NEC states that if there are fastened in place loads on the same circuit with lighting and cord connected utilization equipment, the fastened in place loads can't exceed 50% of the circuit rating. Reading on, any one single cord connected utilization equipment can't exceed 80% of the circuit rating. Most motors would no doubt require a separate circuit. I suppose if a pool pump were cord connected and there were provisions for quick disconnecting on the water (unions) it could be considered not fastened in place but that might be a stretch. My call would be a separate circuit [Linked Image]
