How to Wire a Range Cord
How is a Built In Electric Range and Oven Wired? Wiring a Range with an Oven, 3Wire and 4Wire Options.
Wiring a Built In Range or Oven
- 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?
