Circuit Breaker for a Kitchen Cook Top
How do I connect the wiring for a cook top stove? Wiring a New Cook Top to Replace the Old Cook Top.
Circuit Breaker Size for an Electric Cook Top
- I am installing a new electric cook top to replace an older electric stove.
- The old unit had 240V 50A service using 6 Gauge cable.
- The new glass surface cook top only requires 240V 40A service.
- Is the current service OK, or should I replace the 50A breakers with 40A breakers?
- I assume the heavier cable is not a problem.
This electrical wiring question came from: roger, a Handyman from San Francisco, California.
Additional Comments: Well laid out and the Question process is very easy. Thanks.
Thanks for your electrical wiring question Roger.
How to Connect Electric Cook Top Circuit Wiring
Application: Wiring a Cooktop Stove.
Skill Level: Intermediate to Advanced.
Tools Required: Basic Electricians Pouch Hand Tools and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical circuit wiring.
Notice: Installing additional electrical circuit wiring for a cook top should be done with a permit and be inspected.
Wiring a Cook Top
- The cable size of the existing stove circuit is fine, however if the glass cook top is specifying a 40 amp circuit, then the existing 50 amp 240 volt circuit breaker should be exchanged for a 40 amp 240 volt circuit breaker.
IMPORTANT: Installing a Glass Cook Top
- Be careful when installing glass cook tops!
- The glass tops are extremely fragile and the lower mounting screws should not be tightened too much.
- Consult the installation manual for specific instructions to avoid cracking or damaging the glass cook top.
Example: Wiring a New Cook Top to Replace the Old Cook Top
Richard asks the following question about Replacing an Old Cook Top with a New Cook Top:
- I am installing a new electric cook top.
- The old cook top wiring was:
- Black to black, white to red and bare ground to bare ground.
- I don’t understand how this worked at all.
- The new cook top wiring is now Black to Black, Red to Red, bare grounds together.
- Now I do not get any power to the Red Leg. Do you have any suggestions?
Home Electrical Circuit Wiring for a 240 Volt Cooktop
- Some of the older 220 volt circuit wiring used a 3 wire cable which included a Black, White and Ground wire.
- The White wire of the circuit was used as one of the power legs which are now required to be identified with red electrical tape or red permanent marker.
Cooktop Circuit Specifications, and the Home Electrical Circuit for the Cooktop
- Because the electrical specifications for all cooktops are not identical, the cooktop circuit of the home that you are connecting to should be verified for the voltage and amperage, and then compare this to the circuit specifications of the new cooktop to make sure they are both compatible with each other.
NOTE FOR ELECTRICIANS: Using a voltage tester will help identify the wires of a 240 volt circuit.
