for a 240 volt hot water heater 50 gal whirlpool i have three wires from the breaker red black and white and only a red and black on the water heater how do i tie them in but there is a small copper line for the ground ?? should I attach the white to the ground nut on the hot water heater?
The white wire is hot and so is the red the black is not hot according to the tester I am concerned...the old hot water heater was black to white and red to red and the black wire had a wire nut on it
should i set it up the same way white to black (which register juice) and red to red (which register 240 on the meter)
