    I have been plumbing 27 years and have installed many electric water heaters , my latest installl the water heater had a a dryer cord used for the power supply that plugged into the wall I wired the giant pigtail while waiting for the old water heater to drain which was full of calcium. I installed the new water heater and removed air from the the line by opening the tub valve. I switched on the power and had a short. The ground screw had pierced the dryer cord on the inside and caused the short but it took awhile to find this out. Lesson learned be wary of giant pigtails.

      Yes thanks for sharing. Some years ago a cord and plug connection served as a means of disconnect if the breaker or fuse panel is not within sight of the unit, to protect someone repairing the water heater from being electrocuted if someone else turns the power on. Electric water heaters are not UL listed for cord and plug connection and I don't know that they ever were, nonetheless I have see it done a couple of times in homes 30 years old or more. Instead the unit should be hardwired with 10 guage copper wire connected to a disconnect safety switch or a double pole toggle switch rated for 30 amps near the unit if the breaker box is not within sight.

    Great video and highly informative. I reviewed my BradfordWhite service manual which says the following in regards to diagnosing the heating ellement: "Reading should be 12.8 ohms (±6%) for a 240volt, 4500 watt element. A reading outside the range using the formula above (±6%), indicates a bad element and the element must be replaced." So I checked both upper and lower elements and my multimeter shows 12-13ohms initially and as I held the multimeter on the contacts the reading dropped to 9.5ohms after 4-5secs. Im not sure whether to go by the initial 12-13ohm reading or the 9.5ohm reading 5secs later. Do you think I have a problem here? The heater is the M250S6DS-1NCZZ and id about 15 years old. Thanks in advance for any further info.

      That would depend on the location and the electrical codes for the specific area, and this may be required for other countries.
      For Example:
      In California a disconnect is not required for a water heater.
      Otherwise if you would like to install a disconnect then you may do so by all means.

    • @AskTheElectrician

      In the USA, for a typical 240volt 30amp water heater circuit in an older home, where the wires are black, white and a bare copper or a green ground wire, in many installations the white wire was used as a power wire and attached to one terminal of the 2pole circuit breaker, and the black wire on the other terminal of the 2pole circuit breaker, and no - it does not matter which position these wires are in as attached to the 2pole circuit breaker. It is always best to identify the white wire as a power conductor using red electrical tape at the circuit breaker and at the water heater. Make sure to verify the circuit wiring as described.

    question concerning wiring.? My electrical panel has a 30 amp breaker attached to a 10/3 wire which goes to the water heater space, but the water heater an AO Smith 100 only has 2 wires from it a red wire and a black wire. plus ground of course ,but my question is do I at the water heater tie wiring black to black and white to red or red to red and black to black then using a wire nut to cap off the white wire?

    • @AskTheElectrician

      Typically when there is a 10/3 with ground to a water heater the white wire is not used, therefore it is capped off, then all the connections are color to color. It is best to verify the wiring to make sure the black and red wires are in fact the power wires, as they should be.

      Thank you, glad the video was helpful.
      Double check the electrical circuit specifications on the new water heater to make sure it requires a 30amp circuit, only because not all water heaters are alike, and some for mobile homes may be small - so check this.
      If a new circuit is required then a new cable may be required to be installed from the water heater to the electrical panel, all according to code. If the existing water heater circuit will not be used then it may be disconnected and removed, and the new circuit breaker could take it's place. The qualified installer will need to be aware of all applicable codes that apply to the project.

    Hello, so I'm in the process of replacing my sister's old 2008 water heater that just started leaking this weekend. As I was inspecting the whole area around the water heater, I noticed the electrical wiring (with romex) for the water heater, was coming out of the floor (just a hole drilled through the wood flooring with no grommet) and free floating up and over to the top of the existing water heater. Would using flex and then securing that along the closest wall be a good way of protecting the wire?

I seem to remember #12 ga being used over the years but not sure that is correct? This hwh was wired right except for the black wire from the lower Tstat was on the upper Tstat left side bottom screw and the upper element had its wire on the upper Tstat right side bottom screw. So, they were reversed and that would seem to cause the lower element to come on, but the top I don't think it would ever come on? What is your opinion?

    • @AskTheElectrician
      @AskTheElectrician  Před 7 měsíci

      The internal wiring of a typical water heater is factory wired, therefore the installer only has to be concerned with the main circuit connections. The only time we would need to access the other areas is if the water heater element, or one of the controls becomes faulty and needs to be replaced. But you are correct, some of the internal wiring is not #10 because there are two elements that do not pull 30amps each. Great questions - Thanks for viewing the video and sharing your thoughts.

      It's not so much the size of the wire that determines how many amps can flow as the temperature rating of the insulation. That's why the wires in the unit are smaller than the supply wires. You can get some really high temp insulation, like asbestos cloth like is used in ovens.

The 20 AMP circuit is wired to 2 receptacles that no longer works, it wired to Hot to circuit, neutral and ground to bus bar. Can I disconnect the 20 AMP circuit? And is a water heater supposed to be getting power this way? The old water heater was wired this way for more than 20 year's? I'd appreciate if you could help or give me some insight?

      The water heater has 2 heating elements, 1 at top, 1 at bottom. Each element does not use 4500watts, however if both heating elements are on at the same time they together will draw 4500 watts (or less depending on the specific water heater and the factory settings for each heating element). So because each of these elements consume less watts they are wired with the smaller #12 wire.

      First let me insert this here: The water heater has 2 heating elements, 1 at top, 1 at bottom. Each element does not use 4500watts, however if both heating elements are on at the same time they together will draw 4500 watts (or less depending on the specific water heater and the factory settings for each heating element). So because each of these elements consume less watts they are wired with the smaller #12 wire. Now as for your other question, no, typically a water heater circuit is a dedicated circuit which is installed from the panel directly to the water heater location. The circuit and sub panel you are referring to sounds very questionable and should be inspected to figure out just what is going on, and how or if it should be used. The wiring is in place, but it needs the purpose needs to be determined.

    Hi. I need your expert assistance if you don't mind. I need to add a booster pump to my electric heater. I tap the power wiring from the heater wiring itself. Is this safe? What is the risk?

    • @AskTheElectrician
      @AskTheElectrician  Před 2 lety +1

      Typically a booster pump is wired from a separate electric circuit, and the booster pump is not wired to the water heater circuit. Keep in mind that most booster pumps in the USA are 120volt with small amperage, and our conventional domestic water heaters are 240volt 30amp. The concern is the booster pump requires less circuit power and the wiring is smaller, therefore we must provide over current protection for the booster pump, and we must provide the correct voltage.
      The only exception is when a water heater has a booster pump built into the main water heater unit and the internal wiring components provide the necessary circuit provisions and circuit protection.
      Be Safe and Be Careful.

    I bought this water heater czcams.com/users/postUgkx8G49mV71sAzUl9shXyLW-r3XgHH9EVh1 for use in my bus conversion. I installed it under my kitchen sink and it is fed by a high efficiency on-demand LP water heater. It is both a backup hot water source as well as a water saving device since we have hot water on demand rather than having to wait for the gas on demand water heater to finish its ignition cycle. I decided on this water heater due to the fact that it only draws 1300watts when it's ON instead of the 1500 watts that most Water heaters this size draw. In an RV a couple hundred watts can be a big deal. With very low standby losses, I don't have to worry about excessive power consumption. When propane is not available for our gas water heater, in conjunction with our low flow shower head there is enough hot water available to shower, albeit we won't be taking "hotel showers." Also very happy with the recovery rate of this water heater. Granted, it is quite small, but it does exactly what we need it to do.

    Hello! I have a bit of an issue. Yesterday I wanted to change a ceiling fan/light to a light fixture in my kitchen.
    I was unable to wire everything correctly and there was a short circuit - I went to the main fuse box and saw that the kitchen fuse was blown. I got a new fuse and replaced the broken one. Everything was working fine after that.
    After that I went to the basement and tried turning on the lights, they did not work nor did some of the outlets in the basement. So I went back to the main fuse box to check those fuses, taking each one out and putting a new one in to check if that was the issue. That didn’t work.
    The outlets are not GFCI so I don’t know if it’s the wires or something else. Any help would be immensely appreciated!

      Sorry to hear about this problem John. You have stated that "I was unable to wire everything correctly and there was a short circuit" therefore attention should be given to correcting the initial wiring, because all of the issues you have described point back to the fact that something is definitely not wired correctly at the location of the original work - where the ceiling fan\light was located. Identifying the individual wires will be essential before one can make the correct wiring connections which will restore everything to the original functions.

      You can but as the elements are rated for 240 and your only supplying 208 your btu output of the heating elements will be in proportion to your decreased voltage. But that may be ok. Just raise the setting on the heating element thermostats, unless they are maxed out. The water will not heat up as hot, the elements won't get as hot, but you may be ok with that.

      Because the Water Heater Circuit is wired according to NEC Code: 310.16, Table 310-16, Utility room, panel, circuit, 30 Amp Breaker for water heater.
      Therefore a 30amp circuit requires a 10/2 w/Grd Type-NM Cable - in most installations.

      Also in article 422.13 of the national electric code which states "The branch circuit over current device and conductors for fixed storage type water heaters that have a capacity of 450 L. (120 gallons) or less shall be sized not smaller than 125 percent of the rating of the water heater. So if your water heater is rated at 4500 watts at 240 volts, which is 18.75 amps, you then have to multiply 18.75x1.25=23.43 amps. Therefore you will need a minimum circuit rating of 25 amps with#10 AWG conductors.
