Can a Refrigerator and Microwave Be on the Same Circuit?

Microwaves and refrigerators are heavy-duty appliances that use large amounts of energy and therefore need to be powered by a dedicated circuit. A dedicated circuit is designed for use by only one appliance.

Microwave.

Function

Appliances such as microwaves and refrigerators need circuit wiring that can carry a large enough current. The wire and circuit breaker size depend on whether the appliance requires 120 or 240 volts of power.

Features

Microwaves and refrigerators should each have a properly grounded circuit with a 15/20 amp circuit breaker or fuse and a #14 gauge house wire at minimum.

Significance

It is always recommended that microwaves and refrigerators have their own dedicated circuits. Depending on the area, local housing codes may mandate specific wiring requirements.

Solution

A professional electrician can help determine the best wiring setup for your kitchen appliances.

Warning

If a microwave and refrigerator share a circuit, frequent tripping of the circuit breaker may be experienced or, worse, melting of the electrical wire and a potential fire.
