Situation as follows: 24 foot diameter aboveground pool. 100' from house, fed with #10 THHN insulated in nonmettalic conduit to allow for voltage drop. 1 HP pump with bonding lug plug into GFCI receptacle. The bonding is completed by a #4 wire from bonding lug on pump to ground rod driven and then to metal supports of pool.
Problem - When the bonding wire is connected, the water surface becomes energized. When the bond is removed from the pump, no problem.
The pool is not in my jurisdiction, but I was asked to review the situation. The only problem I saw was the stranded bond wire in lieu of solid. What could be casuing the electrical charge through the bond lug other the motor malfunction. The voltage tested from the lug to the ground rod ranged from 2 volts to as high a 26 volts. Any thoughts?
