What would be the result if an electric hot water heater wires were
reversed?
If the wires going into the hot water heater were red wire to black, black
wire to red, what would be the result when the hot water heater was
started
up?



Assuming they were properly wired in the breaker box, both of them attached
to the hot side of the breaker, it would make absolutely no difference.
Red and black are interchangeable.
