I have a 1 hp submersible pump located in a lake using it for irragation yesterday was cleaning silt from pump just had turned it off about 10 minutes prior to cleaning it and when I touched the pump it knocked the fire out of me. Do you think something is wrong because the breaker was turned off, is there something I should check and what causes this? the pump seemms to be wired correctly it is 220 and it is wired to a 100 amp service box located in garage. Before when I moved the pump and it was turned off for a while it didn't do this, I ran 500 ft. of 10/2 wire any help would be appreciated.
