How to Keep Oven Electrical Wiring Safe

Electrical Question: I have just bought a new built in oven but it has a plug as opposed to being hardwired. The unit that is being kept is gas. My concern is what happens to the electrical wiring that will not be used. I need to keep the oven circuit on as this ignites the gas.

This electrical question about an oven came from: Michelle who is a Homeowner.

Thanks for your electrical question Michelle.

Installing a Gas Oven and Safe Keeping for the Existing Electrical Circuit

  • Michele, the existing electrical circuit wiring may be capped off and safely stored in an approved junction box where a blank cover would be installed.
  • The 120 volt cord and plug that came with the new gas oven is required for the electronic ignition and the time and bake controls.
  • If a 120 volt receptacle outlet is not available then a qualified electrician may convert the existing oven circuit so that it may provide the necessary 120 volt outlet which could then be installed in the oven cabinet behind the oven or brought into a cabinet that is above or below the oven.

    Can I remove a 220 receptacle, cap off one 110 leg, and use other 110 for a 110 receptacle? I only need 110 volts for this gas oven.

    • Dave Rongey says:

      Hi Jeff,
      A dedicated 3-wire oven cable which has a separate white, black, red, and a ground wire may be converted to become a 120 volt outlet as long as the circuit breaker is identified and replaced with a 120 volt breaker as well. For example, a 20amp 120volt outlet may be installed and a 20amp circuit breaker would be installed in place of the existing circuit breaker. Black, white and ground 12 gauge copper lead wires would be attached to the 120 volt outlet, which are then spliced onto the appropriate circuit wires at the outlet location. The circuit at the panel would be changed to indicate the converted circuit.
      Please see this article for more information: Converting a 240 Volt Circuit to 120 Volt
      I hope this helps you,
