I installed a GE electric hotwater heater 6 months ago, wiring it to a 100 amp subpanel. The unit does not have a neutral wire, only the 2 hot wires and a ground wire. Could someone please tell me how the ground should be wired in the panel, to the neutral bus or to the ground bus? Wouldn’t wiring it to the ground bus negate the separation of neutral/ground rule? Also, does this heater adhere to code? Is it possible to rewire the heater to make it correct?
Thanks for any help, Jim

The ground should be connected to the ground bus in your subpanel. Connecting it to the the neutral bus will bridge ground and neutral via the plumbing and therefore defeat code. The heater doesn't need a neutral as it doesn't use 120 volts.
