Yes to your question. However, you also indicate that you have a gas water heater so wiring it with 220 volts does not make sense. Be ware. If you are not sure about what you are doing it would be best to get a pro in there

80 gallon tank what is the voltage and how do i hook electric wires to it


Most Larger water heaters are 220 volt ac single phase. This means you need 3 wires, two hot wires one neutral or ground. You will need to come from the breaker box off of a dual breaker of 30 amps or better. See the manual with the new heater. In your breaker box you have two sides or in coming service. The right side and the left each side is hot 110volts ac. you need to pull one leg (hot) from each side into the dual breaker out to the heater connections. The ground or neutral wire is un-insulated copper. Run these wires out to the heater. One black hot at 110 vac, one white hot at 110 vac and one plain copper ground.

I replaced all parts but water heated won't get hot


You have electric water heater.
You replaced elements and thermostats but heater still won't work.
And tank was completely full of water, and water was running out of a faucet before turning power ON.
If elements are not fully immersed in water, they will instantly burn out.
If upper element is burned out, then tank will have NO hot water.
If lower element is burned out, and upper element is not burned out, then tank will have some hot water.
http://waterheatertimer.org/How-to-test-water-heater-element.html
http://waterheatertimer.org/How-it-works.html

If elements did not burn out, then that leaves 1 main suspect: the electricity.

1) Push in ECO red reset button on upper thermostat. If ECO is tripped out, then heater will not work.

2) Click circuit breaker all the way one direction and then back the other direction to make sure breaker is latched.

3) If tank has 2 elements, then it is 240volt.
If 1 leg of 240Volt circuit is not working, then 240V appliance will not work.
240Volt circuit needs both hot wires to complete the circuit:
http://waterheatertimer.org/How-to-wire-EH40-hot-water-heater-timer.html#120-240

Buy cheap multimeter from Home Center and set dial to 240-250-277VAC
Tape tester leads to woods sticks to keep hands away from power.
Power is ON
Test across top 2 screws on upper element should show 220-240 volts.
If you have 240 at top two screws, then skip down to step 6.
If no reading across top two screws, then move to top of tank.

4) Open connection point where wire connects to heater.
Test across both insulated wires should get reading of 220-240 volts.
If no reading, move to circuit breaker box.

5) Mark water heater breaker.
Turn off all breakers except water heater breaker and main breaker. (and breaker to light fixture where box is located)
Do not hold or touch or lean against anything metal.
Stand on dry boards and wear dry clothes.
If main breaker is OFF, the big wires that connect to main breaker are still HOT.

Remove box cover.
240Volt breaker has 2 wires connected with screws.
Test across both screws for 240Volt.
See if wires are loose.
If there is no reading, then breaker is not working on one leg.
To double check, move water heater wires to another same-size 240V breaker and then put ear against water heater to listen for bubbly-fizzing sound.

6) If you are getting 240 to water heater, then wire inside tank could be loose.
Do 30 minute troubleshoot:

Is the lower element suppose to have two legs of 120 to it? Or do i need to move a wire up top to make it 240? as it is on top element.


You have water heater with two elements.
Two-element water heaters are 240Volts.

1) Lets talk about what makes a 240Volt circuit
See basic water heater circuit:
http://waterheatertimer.org/B220C.html

Open link, and illustration at top of page is your water heater circuit

Notice that two insulated wires come from the circuit breaker and go to the water heater.
These two wires are 120volt each. When these two 120Volt wires combine, they create 240Volts
These are called hot wires because they come from the hot busbars.
There is also a bare copper wire that comes from neutral busbar.
The bare copper wire is a safeguard, and is not necessary for the 240V circuit to work.

Inside each circuit breaker box is 1 neutral busbar, and 2 hot busbars.
Open image below, and it shows typical residential breaker box
http://waterheatertimer.org/images/Inside-Main-Breaker-Box-420.jpg

In a residential home, each circuit takes two wires to complete the circuit.
For 120Volt circuit, you need 1 neutral wire and 1 hot wire to complete the circuit. These are usually a black and white wire. The bare copper wire is a safeguard.
For 240Volt circuit, you need 2 hot wires to complete the circuit, and each hot wire comes off a different busbar. These can be a black and white wire, and sometimes a black and red wire. The bare copper wire is a safeguard.

With a 240Volt water heater the two hot wires connect to the black and red wires located on top of water heater.

2) Let's talk about wiring inside a water heater.
http://waterheatertimer.org/images/WH-w-combined-530.jpg

Open image on link above, and it shows your 240volt water heater wiring.
The 2 hot wires from breaker box connect to the red and black wires on top of heater.
Inside each water heater, the wires are color-coded and will appear the same, or nearly the same, as shown on link above.
As long as your wiring appears like the image, and the hot wires from breaker box connect correctly, and the circuit breaker is working fine, then your water heater will work.

No hot or warm water what is the voltage reading susposed to be on the heating elements? I have 122 volts on each terminal on both elements but no action, what am i doing wrong?


If water is totally cold, then upper element is not getting 240V. Since element tested for 120V, then that says upper element is burned out, upper thermostat is bad, or circuit breaker is bad.
Best thing is to buy multimeter and do 30 minute troubleshoot:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html

Also read information below for understanding how water heater works.

Testing elements for voltage can be misleading.
If water heater has 2 elements, then tank is 240Volts.
240V water heaters have 120V on each element at all times.
So elements have hot 120V power, but they are not turned on until the circuit is complete with 240V.
Open following links to read specifics about 120V and 240V
http://waterheatertimer.org/B220C.html
http://waterheatertimer.org/How-water-heater-thermostat-works.html

240V is made from two 120V Hot wires from breaker box.
Each 120V line from breaker is called a 'leg.'
So 240V circuit has two legs, and both legs need to be turned on to complete 240V circuit.

Water heater thermostats turn off only one leg.
The other leg is Hot all the time.
So when you test screws on an element, for example test between a screw and any bare metal part of tank, then the screw will always show 120V.
That is just one leg of the 240V circuit.
But the 240V circuit is not turned On until both legs are connected.
Every residential circuit needs two wires to complete the circuit, and in the case of 240V, those two wires are both 120V.

When the thermostat turns on, it turns on the second leg to the element and that completes the 240V circuit.

JUST PURCHASED A RELIENCE 602 ELECTRIC HOT WATER HEATER 50 GALLONS TO INSTALL IN MY HOME WHAT GAUGE WIRE AND BREAKER DO I NEED TO INSTALL


The hot water heater should come with an amperage rating on it.
They vary from 30 to 40 amps, and then 10 or 8 gauge wire.
(All hot water heaters are 220 volt.)
I believe the 602 uses a 4500 watt element.
Divide 4500 by 220, and you get about 20 amps.

If you want to be on the safe side, you go with the heavier wire, 8 gauge, and then go with the smaller breaker that is more easily tripped, 30 amps. That way you can switch to a 40 amp breaker in the future, without having to change the wiring. The goal is to always make sure the wire is rated higher than the breaker. You want you breaker to trip before your wire melts.
But technically a 30 amp breaker and 10 gauge wire would be fine for this heater.

And since it is 220 volt, you will always use a double breaker.
That is because 220 volt appliances don't use a ground, but instead use the potential between to power wires that are 180 degrees out of phase. AC always does a sine wave, and the 2 power leads coming into the house are always out of phase. When one is 110 volts up, the other is down. So the total between them is 220 volts. And the way they intentionally zigzag the breaker box, 2 breakers next to each other always are on opposite power lines.

If you have any doubts at all about 220 and water heater wiring, please ask again. Wiring is not hard, but you have to understand what you are doing, or else you can cause serious consequences.
For example, if you use wire nuts or wrap wire around a screw, you need to always turn them clockwise, so they pull the wire when tightened.
You also always need to ground the chassis with a green safety wire.
Since a 220 hot water heater uses 2 power wires and a safety ground, the white wire should be striped with a permanent marker, so that it is not confused with the white neutral wire of a 110 volt appliance.

Water too hot and goes cold within minutes (electric)


The heating element must be shot. There is an adj there, but it is a tiny dial, and I'm not sure about the 30 gal, but most heaters have 2 elements. If yours starts out too hot then runs out, Blame the element, or check the breaker with a meter to make sure you have voltage to both legs of the 220 volt line. Sometimes one will quit there, and leave you half power. Check it out.

My hot water isnt working and i need to know if the pilots go off on an electric water heater like gas if so how do i re lite the water heater


  1. if your hot water heater is electric there is no open flame or pilot light. They have electric heating coils,normally they are 220 volts.Follow the metal conduit up and back to the box check the breakers there will be two of them in for the hot water heater if it is 220 there will be only one fuse/breaker if it is 110. Check to see that they are on.
