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?

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.
