Couple of winters ago my cows were reluctant to drink from the tank after I put in the heater (submersible, or the floater). The tank is galvanized, I installed a ground just for the tank, and connected the tank to the rod with copper.
When the snow we tracked into the shop melted into the cement floor ya got 110 volts off the doorknob (no amps, I guess, cause no one got knocked down). Circuit Tester showed all the oulet circuits were messed up, every combination of lights depending on which side of the panel you were on.
Went down in the well pit where I had plugged the heater in. The tester said the putlets were dead. I knew they weren't because the heater was heating the tank. Turns out that the elctrician used romex two conductor with ground thru PVC from the shop to the pit, the pump is 220V. When he wired the 110 outlets he split the 220 by running neutral for the outlets back on the ground!
