    I have a similar problem. After 6 years I went to clean the bottom of my tank and I noticed the lower element was never connected. The Ruud 65gal tank has two 4500 elements. The upper draws about 16 amps and the lower about 17 amps. After about 2 to 3 minutes the 30 amps breaker gets warm and pops.
    Is this the normal amps rating for this type of heater?
    Should I replace the breaker with a 40 amp one?

Typical H2O heater with 4500 watt elements should draw around 18 amps. Check to make sure the connections for the wires at the breaker are tight, loose connections will cause the breaker to heat up. If all of this is good and the breaker is still heating up, it is time for a new breaker.

Have 40 gallon electric hot water tank 10 gauge wire 20 amp double pole breaker federal pacific fuse box red black ground wire shows power on 2 hrs now not even Luke warm water what could be wrong


I'm an electrician and can help. Federal Pacific equipment is tough stuff. The company went out of business decades ago - due to faulty equipment they made. Aside from that..

There may be no power out of the breaker, bad connections between the breaker and water heater, bad thermostat, bad hi temp sensor, bad heating element and more. I wrote the article linked below - that will help you find and fix any of these problems and more - assuming you have the equipment and ability to work on electric water heaters. If not - call a licensed electrician.

Hot water recover time


No.
Fold-back elements are low-watt-density, so element does not burn out as easily since heating is spread across more surface area. But recovery remains 16 gallon per hour.
20 amp breaker and 12 gauge wire: max 3800 watts
30 amp breaker and 10 gauge wire: max 5800 watt.
4500 watt element heats 20 gallons per hour.

Instead of changing elements: Set thermostats higher so more cold is added to hot water, and then you have more hot water available inside tank.

Electric Water Heater blows fuse, but only every few years


Your residential water heater is not 9000 watts. Or it would blow the fuse every day and melt the wire. Instead, you have dual-element non-simultaneous 4500 watt water heater.
http://waterhatertimer.org/How-it-works.html
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html
Look at label for 'total connected watts'
http://waterheatertimer.org/images/Whirlpool-energy-smart-watt-rating-IMG_2600.jpg
25 amp breaker or fuse and 10 gauge wire is minimum acceptable for 4500 watt water heater.
http://waterheatertimer.org/Color-code-wire.html
Troubleshoot blowing breaker or fuse:
http://waterheatertimer.org/How-to-troubleshoot-electric-problems-with-water-heater.html#trip-breaker
Why does it blow fuse once each year?? I don't know.
Fuses and breakers trip when overheating occurs on wire.
Each fuse or breaker is rated for heat, and over time, it will get hot and then cool and then get hot again ... this action weakens fuse or breaker.
To solve problem: install 3500 watt elements (and clean sediment out of tank). Wire will run cooler, and fuse will last longer. Whole fuse box will demand less power, and run cooler, and will last longer as a result. So there is less stress on electric service panel.
http://waterheatertimer.org/How-to-replace-water-heater-element.html
3500 watt element will heat water to same temperature, but takes longer. For example: 4500 watt heats 21 gallons per hour, while 3500 watt heats 17 gallons per hour.

Rheem 50 gallon Electric Water Heater 81V52D C repair ideas needed


It could be element shorted to ground through steel tank, so don't touch tank when breaker is ON.
Or you have undersized 12 gauge wire and 20 amp breaker and the heat has loosened breaker on the busbar. Breaker trips when heat exceeds breaker limit. Jiggle breaker and listen for crackling sound.

To restore hot water now:
Turn off circuit breaker, and open top cover then Push in reset button on top of heater to restore functionality. Put back insulation and factory cover.
To fix water heater: test and replace bad element.

Need to increase the recovery rate of Rheem 82SV30-2 elect water heater. Has 4500w upper and 3380w lower elements. Was told by County Health Dept that it was possible to wire both elements together for...


Basic information: Typical electric water heater operates in non-simultaneous fashion where either the upper element is ON, or the lower element is ON, or both elements are OFF, but both elements are never ON at same time.

Easiest way to increase recovery. If you have 10 gauge wire and 30 amp breaker, then install two 5500 watt elements. This will not work if you have smaller 12 gauge wire and 20 amp breaker.
Watt rating appears on side of each element.
http://waterheatertimer.org/How-to-replace-water-heater-element.html

Change wiring.
If you run two separate 10 gauge wires to water heater, with each wire on a separate 30 amp breaker, then you can 'wire both elements together' to operate in simultaneous fashion. The elements are each wired independently of each other, but they can both turn ON at same time, and this action avoids heating lag if you also install larger 5500 watt elements.
Simultaneous water heaters can be ordered from manufacturer, and this is common with 80 gallon models where tank must keep up with larger demand.

Hello - I have a 6-7 yr old Whirlpool EnergySmart 50 gallon 5500 watt water heater. (Two control boards fried and were replaced free). Symptom now is not enough hot water. No 'error codes' are blinking...


1) Residential water heaters are non-simultaneous. Only one element works at a time.
Upper element comes on until top of tank is heated, and then lower element is switched on until lower part of tank is heated. Lower element keeps tank hot during standby hours
http://waterheatertimer.org/How-it-works.html

2) Typical Whirlpool energy smart has 4500Watt elements. Look at label on side of tank
If both elements were ON, that would draw 9000Watts or 37.5 amps, requiring 50 amp breaker and 8 gauge wire. V x A = Watts.
All dual-element tanks are 240V.
Whirlpool energy smart requires 10 gauge wire and 30 amp breaker so electronics are not starved during operation. If your wire or breaker are undersized, that is suspect for repeated failure.
http://waterheatertimer.org/Whirlpool-Energy-Smart-electric.html

3) Typical electric water heater heats 21 gallons per hour. First hour delivery is higher since elements heat water as you use it. Overall however, electric water heater cannot re-heat as fast as gas because gas water heater burner carries more BTU punch per minute than electric element. Gas heats about 41 gallons per minute, with higher first hour delivery.

4) IF YOU HAVE OLDER energy smart and installed newer board, then you could have non-simultaneous operation is reversed so that lower element comes on first.

Contact Whirlpool 1-877-817-6750

5) Another potential problem is that you have sediment inside tank and that is reducing efficiency of lower element.

Can i replace 4500watt elements with 5500watt on a 606 model


1) Manufacturer's warranty will be voided, and I've never seen recommendation that suggests better heating or saving money from replacing 4500W with different wattage element.

2) That being said, you have 240V water heater.
4500Watts divided by 240 = 18.75 amps
5500Watts divided by 240 = 23 amps

20 amp circuit breaker with 12 gauge wire is rated for 80% of load = 16amps
30 amp circuit breaker with 10 gauge wire is rated for 80% of load = 24amps.
http://waterheatertimer.org/Figure-Volts-Amps-Watts-for-water-heater.html

3) You can use 5500Watt element if you have 30 amp breaker and 10 gauge wire.

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.
