![]() 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.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.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.The 240 volt circuit breaker of the circuit is turned off and the circuit wiring is removed from the circuit breaker.The circuit wiring and the circuit breaker must be identified at the electrical panel. ![]() The Wire Gauge and Type must be sized and approved for the amperage of the existing circuit.A junction box must be installed in an accessible location for the circuit wiring.Here are the Basics of converting a Dedicated 24o Volt Circuit to a 120 Volt Circuit Notice: Installing or modifying circuit wiring should be done according to local and national electrical codes with a permit and be inspected. 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. Precaution: Identify the panel circuit, turn it OFF and Tag it with a Note before working with the wiring and components. Tools Required: Basic Electricians Pouch Hand Tools and Electrical Tester.Įstimated Time: Depends on personal level experience, ability to work with tools and install electrical circuit wiring. ![]() Skill Level: Intermediate to Advanced, Best installed by a Licensed Electrical Contractor. How to Convert From 240 Volt to 120 VoltĪpplication: 240volt to 120volt Circuit Wiring. Thanks for your electrical question Robyn. This electrical question came from: Robyn, from Cincinnati, Ohio. How can you do this? I don’t see how with extra red wire and no ground? Any suggestions? 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. The original wiring is black, white, and red no ground that I can see. We took out the wall oven and wanted to add a dishwasher. If yu have older, ungrounded 220-volt outlets, Clover Electric can rewire your appliances with four-wire plugs and install four-prong 240-volt outlets to ensure they are safe and compatible with newer appliance plugs.Dedicated Circuit Conversion from 240 Volts to 120 VoltsĮlectrical Question: I’m working with a Kitchen remodel in a 1961 ranch style house. However, in older homes you may find 3-prong plugs without a ground. A 240-volt outlet is larger, with rounded tops, and employs two 120-volt wires, plus a neutral wire. A standard outlet has a 120-volt wire and a neutral wire that delivers power using one phase of your electrical service. You can tell a 120-volt and 220-volt outlet apart by the size and configuration.
