What would be the result if an electric hot water heater wires were
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
Your water will be the wrong polarity. When you open both the hot and cold
faucets, it will not mix properly. Sort of line trying to get two magnets
to stick together when the N & S are reversed. In the washing machine, the
agitator may overcome it, but showers will be most uncomfortable.
I understand what everyone else were saying on here, and I am not an
electrical expert..but.. wouldn't it depend on how the wire is connected at
the electrical panel. What would happend if your red is connected to the
'hot' point and the red is wired to the neutral (white)?
Can someone else add to this?
A water heater requires 240V. When correctly wired, the black and red
wires supply the 240V. "Correctly wired" means that the black is connected
to one side of the hot feed in the panel, and the red is connected to the
other side. There's 240V between them, and 120V from either one to neutral
It simply doesn't matter "which way around" they are.
There is _no_ neutral needed in a 240V water heater. Just two hots
and a protective ground (usually bare).
If, on the other hand, the electrician wired one of the wires of the
HWT (red or black) to the neutral (coloured white in cables, one
of the busbars in a panel), the HWT is only getting 120V, not 240V.
The HWT will work, but it will take a very long time to heat up.
