Water heater installation
#1
I am installing a new electric water heater. I had to purchase a metal cable with electrical wires inside to extend the wiring. The old wouldn't reach. The old has two blue wires and two red wires. The new cable has one black, one red, one white, and one green. The wires coming out of the new water heater are black and red, one each. I have to connect these three together. Please tell me what connects to what.
