Electrical Circuit Requirements for Kitchen Ovens
I am installing an oven that is 240 volt, what type of dedicated circuit do I need? How to Wire a 240 Volt Oven Circuit: Kitchen Oven Electrical Wiring and Circuit Requirements.
Wiring a 240Volt Oven Circuit
I am installing a double wall oven that is 240 volt. Do I need a 20amp circuit, or will the current 30amp circuit be OK?
- I just bought a Kenmore 27″ double wall oven Model #48763 – 240V, 60HZ.
- The Red and Black wire on the back of the oven has 12 AWG. And the specifications from Sears has Breaker/Copper Wire size (240v) – 30/10.
- The installation instruction on page 3 says, “if less than 4800W, then 20A protection circuit is recommended.”
- I currently have #10 gauge wire and 30 amp (30 each on 2 handles)in the breaker box.
- Do I need a double 20amp as one Electrician is telling me, or will the current 30amp breaker be OK.
- Also another Electrician says I need to rewire to #8 gauge wire for the oven to work. Is this true?
Thanks in advance for any input you can provide.

Electrical Wiring a 240 Volt Oven Circuit
- The size of the circuit breaker is always determined by the electrical appliance as long as the circuit breaker size will not be greater than the capacity of the circuit wiring for that specific circuit.
- Reducing the circuit breaker size is fine, as in your situation which will provide the right protection for the internal wiring of the oven wiring, that being #12 AWG.
- Identifying the specific model of your oven and following the manufacturers instructions is always best.
- Then you must always compare the required circuit to your existing circuit to determine if any changes must be made.
