Electric water heater wiring is a critical step that must be done correctly when installing a new electric water heater. The tools, equipment and knowledge needed will vary depending on a number of factors.
Electric water heater wiring should not be attempted by a DIY person without the proper expertise and knowledge of electrical wiring.
Any job requiring electrical wiring should be treated with the utmost respect. In a situation where a new circuit breaker or junction box is being installed, it is important to keep in mind the requirements of your local building code.
Remember, your local building code exists to keep you and your family safe. Doing a project yourself that does not meet local code may save you money in the short run but may jeopardize the health or safety of your family, and that is a gamble that is never worth taking.
If this is new construction, you should keep in mind your electric water heater’s requirements when you decide on a circuit breaker. Also, because an electric water heater necessitates a 220-volt circuit, don’t wire the unit until the plumbing is in place.
Until the plumbing is connected, there is always a chance that the location of the water heater may change.
If you are replacing an existing electric water heater, then your circuit breaker should be in place. Double check to make sure that the circuit breaker meets the requirements for your new hot water heater. It is important that you do not fill up the tank with water until the tank is properly wired.
Also, do not turn on the breaker until the tank is filled with water. Because of the risk of electrocution or damage to the new water heater, it would be in your best interest to call a professional to come in and do the job correctly.
Electric water heater wiring, is one project that is best left to a professional.
