    4 wire 100amp service box but only 3 wires?
    I replaced my water heater with a tankless water heater. My service box is set up for hot, hot, neutral, and appliance ground for 220 watt hook up. But the water heater only has 3 wires, hot hot, and "Bare wire" ground. I currently have the water heater connected as, hot, hot, to breaker, and the bare ground wire to appliance ground. Is this correct? As I have been experiencing ground fault type shocks through out the house ever since I installed the water heater. How can I correct this and eliminate the shocks from touching other appliances in the house. Breaker box is in the house,(Trailer), has separate ground wire to the ground, then Hot, Hot, and Neutral to outside pole w/ 100 amp service disconnect box w/ 100amp fuses.
