Wiring a Built In Range or Oven
Electrical Question: How is a Built In Electric Range and Oven Wired?
- I have an electric range with a built in oven and I need help with the electric wiring.
- The home I’m working at has an older kitchen range with a 3wire outlet that has a red wire, black wire and a neutral wire.
- I have purchased a larger used oven and range that is setup for a 4wire connection with a red wire, black wire, white wire and a green wire, so there is no grounding strap.
- I was told that oven range combo will work by changing the outlet to 4wire outlet. Is that okay?
- If I change the oven range combo wiring to a 3wire setup can I make a grounding strap using 8 gauge wire with a flat U bend, or round terminals and install a 3wire cord?
This electrical question came from: Richard, a Property Manager from Texas.
Thanks for your electrical question Richard.

The determination will be based upon the combo range oven requiring a dedicated neutral wire and ground wire. When installing a combo range oven unit check the required amperage and voltage and verify that the existing circuit has the same rating.
- If it is permitted by the manufacturer installation manual, it is best to use a 3wire outlet and cord, or a flex and wire assembly.
