Converting a 240 Volt Circuit to 120 Volt
How to Convert a Circuit from 240volt to 120volt: The Basics of converting a Dedicated 240 Volt Circuit to a 120 Volt Circuit.
Dedicated Circuit Conversion from 240 Volts to 120 Volts
Electrical Question: I’m working with a Kitchen remodel in a 1961 ranch style house. We took out the wall oven and wanted to add a dishwasher. The original wiring is black, white, and red no ground that I can see. My father in law had me get 14-2 wire to join with the old wiring in junction box and then the new wiring will go to dishwasher. How can you do this? I don’t see how with extra red wire and no ground? Any suggestions?
This electrical question came from: Robyn, from Cincinnati, Ohio.
Thanks for your electrical question Robyn.
How to Convert From 240 Volt to 120 Volt
Application: 240volt to 120volt Circuit Wiring.
Skill Level: Intermediate to Advanced, Best installed by a Licensed Electrical Contractor.
Tools Required: Basic Electricians Pouch Hand Tools and Electrical Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical circuit wiring.
Precaution: Identify the panel circuit, turn it OFF and Tag it with a Note before working with the wiring and components.
Warning: Working in an electric panel is dangerous due to arc flash hazards and the possibility of electric shock, therefore homeowners and non-electricians should not perform this procedure but rather consult an electrician for assistance.
Notice: Installing or modifying circuit wiring should be done according to local and national electrical codes with a permit and be inspected.
Electrical Circuit Conversion
Here are the Basics of converting a Dedicated 24o Volt Circuit to a 120 Volt Circuit
- A junction box must be installed in an accessible location for the circuit wiring.
- The Wire Gauge and Type must be sized and approved for the amperage of the existing circuit.
- The circuit wiring and the circuit breaker must be identified at the electrical panel.
- The 240 volt circuit breaker of the circuit is turned off and the circuit wiring is removed from the circuit breaker.
- In this case where there is a 3wire circuit, the black wire is used for the hot, the red wire is identified with white electrical tape and used for the neutral and attached to the neutral terminal strip, and the white wire is identified with green electrical tape and the wire is used as the ground and attached to the bonded ground terminal.
- This pattern of identifying the converted circuit wiring is performed at the junction box location as well, and the ground wire is bonded to the junction box and used for the circuit ground.
- A 120 volt circuit breaker sized for the type of wire and the wire gauge is installed into the panel where the black wire of the converted circuit is attached.

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.
