Dedicated Circuit Requirements for Electric Water Heaters
Background: Lonnie, a Homeowner from Oxnard, CA
Question: I am replacing an electric water heater. The original is 240 volts. Can I install a 120 volts? What changes do I need to do? All help is appreciated.
Thanks for your electrical question Lonnie.
Lonnie,Â due to the amount of wattage that a water heater requires a dedicated circuit would need to be installed sized according to the specifications of the water heater manufacturer. This circuit will be either 120 or 240 volts. If there is an existing dedicated circuit with the correct size wire for the new water heater then the circuit can be converted either way by identifying the circuit wiring at both the electrical panel and the water heater location, color coding the wires appropriately and connecting the wiring to the required circuit breaker which is sized correctly to protect the wiring. Terminations to the circuit breaker and the neutral terminal will need to be adjusted for the specified required voltage configuration. Be aware that a 120 volt water heater is less energy efficient than a 240 volt water heater.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
