Hot Water Tank Wiring Question
 
I need to install a used hot water tank into an existing home that had
the tank already removed. So looking at the existing hookup is
impossible since no tank is there.

Two of the wires are hot, so I will simply attach 110V to each wire,
of course being on a separate leg off the box. Where does the neutral
wire attach? To the ground on the tank?

I've searched for a good illustration that described the electrical
hookups to no avail. And with this being a used tank, no instructions
are present.

Please let me know how to hook this up or please point me to a good
illustration on how to do so. Thanks in advance for your help!

How many wires have you got and what voltage as normal is 2 wires
black and white 220 volt

Assuming it's a 240 volt tank, You connect two wires to a double pole
circuit breaker of the proper amperage for the wires,(usually #10 wire on 30
amp breaker) and one wire to the ground bar. At the tank there should be a
green screw or bare wire to connect the ground to. There is no neutral

It's a 240 - 40 gallon tank. Sounds like I was on the right track.
I'll hook up the hot wires to the two exposed on the tank and attach
the ground to the green screw.

Thanks again for your help!!!

If there's no screw-terminal for a nuetral, then the WH probably
has 240V controls, and doesn't need a nuetral. In that case
just wire nut it and leave it unconnected.

Yup ... but just to clarify, the "GROUND" wire is NOT the White Neutral
wire. In a North American 240V system, there is no use of the Neutral.
But, the GROUND wire definitely still has to be attached. It would be
illegal to bond the White Neutral wire to the thank body; it should be
capped and left alone.
You're also required to use a ganged ckt breaker; not just select two
breakers on opposite sides of the load center. That way there's only one
bar to move to turn off both at once. I wasn't sure how you meant to do it
in your original description.

You sound like you havn't done this kind of thing. Please try to
find a wiring diagram for the heater. Also, please find someone
experienced to work with you. This is no place to have a
"learning curve" moment.

Assuming it's a 240V water heater -- there is no neutral. The black and white
wires in the supply connect to the two hot leads on the water heater, and the

That white is SUPPOSED to be red. White is meant to be used for
neutral. Someone's used the wrong cable and failed to make the white
as red.

In what sense is using 10/2 WG to wire a water heater "using the wrong

It's not, but current code would suggest wrapping each end of the white
wire with red (or other color that would designate that conductor as
"hot") tape.

The wires themselves are not wrong. The insulation colors are. It
should have black and red, rather than black and white.

This could have been corrected by properly identifying the white as
being red.

Or by marking it black, or blue, or yellow, or brown, or purple with pink
polka dots and a fluorescent-orange stripe -- basically any color except
white, gray, or green.

Do you care to elaborate on where the hell you would purchase a cable with a
black and a red and no white in it? Using a standard black and white 10-2
in this application is perfectly fine if you mark the white wire as a hot.

When I ran my 10-2 to my heat pump, I just taped the white with black tape.
Done.

"The wrong cable". One with black and white, rather than one with
black and red. Where's the problem?
