My house has some screwed up pool wiring. My pool pump has a 220V line running to it--two hot wires and a white. The white wire is hooked up to the pump's ground in the connection box. However, the white is also split off and connected, along with one leg of power, to a 110V spa pump.
The wire conduit running to the system is plastic, so it's not grounded. It looks to me like there is no proper electrical ground in the way the previous owners wired the pool.
However, the pump does have the heavy duty ground wire running from the bonding lug on the pump to a pipe deep inside a wall. Is this sufficiently safe grounding for the system if there is no ground wire coming out of the conduit?
