How to Wire an Electric Range – The electrical circuit for this oven will need to be tested to be sure that the ground connection is actually present. The installation manual should be double checked to be certain that all of the wiring connection points are correct. |
Kitchen Range Circuit and 3-Wire Connections
Electrical Question: I recently purchased a new electric range with a digital control.
- The instructions allow for a 3wire or 4wire connection.
- I am using the three wire connection from my original cord.
- The digital control will not work.
- I now have a second stove because I thought the first one was defective, but that was not correct.
- The new stove has the same symptom.
- Why will the three wire cord connection not work with the digital control?
This electrical wiring question came from: Bob, an Electrician in Florida.

Thanks for your electrical wiring question Bob.

How to Wire an Electric Range
- The electrical circuit for this oven will need to be tested to be sure that the ground connection is actually present.
- Next, the installation manual should be double checked to be certain that all of the wiring connection points are correct.
- Newer ovens and ranges may require a dedicated neutral wire of a 4-wire circuit.
- This would include the connections at the oven or stove where the oven cord is attached.
- There is typically an adjustment that must be made with the ground and neutral wires to provide the internal oven wiring to be correct.

I am replacing an oven, the old oven is on a 30 amp breaker, the new oven requires a 30 amp breaker- ok there. The wire supplying the oven has a black, white, and ground wire. The wire from the oven has black, white, RED, and green (ground) wire. How do I properly connect these wires?
Hi Allen
You will need to look in the oven manufacturers installation manual to see if a 3wire connection is allowed. If so the manual will describe how to connect the oven neutral and ground wires to the incoming circuit ground wire. However, if your oven does not allow a 3wire connection and requires a separate neutral wire then a new 4wire circuit will be need to be installed.
Enjoy your new oven,
Dave
I have just bought an oven and hob to replace my old ones. The new ones say to wire to an oven socket on its own circuit but the old ones were both wired to separate 3 pin 13 amp plugs sockets. I do not have a fixed 30 amp box on its own circuit. is it safe to wire to the plugs the same as the old units?
Hi Peter,
The new oven and hob appear to have a larger circuit requirement than the original, therefore a new circuit will be required. Connecting the 30amp oven to the existing 13amp circuit would cause an overloaded condition. Be sure to check the circuit requirements as stated in the installation manual.
