Circuit Breaker Size for an Electric Cook Top
Electrical Project #1: How do I connect the wiring for a Cook Top or Stove 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 Project Request process is very easy. Thanks.

Electrical Project #2:

I have an existing electrical cooktop with a 30amp 240volt breaker. The new induction cooktop has a 40a 240v requirement. My neighbor installed the same unit without changing the breaker or the wire and all seems well. Is this an issue?

This electrical wiring question came from Frank in Delray Beach, Florida

Thanks for your electrical wiring question Roger.

Home Electrical Circuit Wiring for a 240 Volt Cooktop

Some of the older 240 volt circuit wiring used a 3wire cable which included a Black, White and Ground wire. The White wire of the circuit was used as one of the power wires. However in many cases the white wire was not remarked as a red wire.
NOTE: The NEC Code requires that when a white wire is used as a power wire that the wire must be identified with red electrical tape or a red permanent marker.
