Tom, I was talking USE cable. It would not extend over 6 ft. inside the dwelling, as I was going to convert over in a junction box just inside the penetration of the outside wall. As of now I have decided just to go with copper conductors # 8 thhn, just to cover the load of the motors and pool light, and general use receptacle. Homeowner does not forsee a "swimming pool heat pumpt" to be installed. Thanks for the information and input.
