No you misunderstood. The GFI is not on the main feeder. It just goes to the hot tub out of the 4 circuit panel. If the main feeder is big enough, I will be coming back out of the 4 circuit panel,( the other two spare spaces) to get the pool pumps. I've got to go back to the job tommorrow to check and see what size breaker is feeding the 4 circuit panel. I'm guessing now that it is a 60 amp breaker since I think the wire is # 6 thhn. Steve..
