My spa has a 50A 220V GFCI made by Cutler-Hammer. A while back I tried to depower the spa from the GFCI by turning the lever to off.... and the spa kept working. The switch can be on or off or in the middle, and I still get 220V to the spa.
Doesn't sound like a safe situation to me. Any ideas for resetting the system, or should I just replace the GFCI?
