Can anyone tell me why a submersible pump has a low voltage charge after the power is turned off?
I have a submersible pump drawing water from the lake. When I turn off the power to the pump, there is still a low voltage charge (12 volts or so) when you touch the pump. I have eliminated the sources for a ground fault. Any ideas why the pump has the low voltage charge?.
The switch for the power may be incorrectly placed in the neutral line rather than the hot line, so even when the switch is off, the pump is being fed line voltage. Leakage to the case within the pump motor, could produce some voltage at the case of the pump.
