Dedicated Circuit Requirements for Electric Water Heaters

[ad#block]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 Wires!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 that I use to easily Detect 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.
The Quickest Way to Check for Faulty Electrical Wiring!The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.
Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..
The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.

Please advice and print a circuit for an Electrical Water Heater fully automatic, named
‘ BERLIN ‘ made by England. This electrical water heater was given by a renovation contractor of which all the wiring had been cut off. The base plate of the heater is 8kw 220v. AC only. The capacity of water volume is approx. 30 liters.
Please sketch a circuit from main power supply to the Turntable nob, the +/- terminals, earthing and the pilot light. Thanking you very much in anticipation and help.
The model number would be very helpful, and the label on the water heater should indicate the amperage and circuit requirements. In US calculations 8kw 220 volt would equate to a minimum 40 amp circuit, however in the UK this may be a little different so for best results please consult with a local electrician who will be able to convert the circuit into UK standards. Be sure to test the internal electrical components, especially the heating elements, because typically when electrical equipment is not functional it is common to cut the connection wires off short to disable wiring of the device.
