According to the 2017 National Electrical Code (NEC), the following kitchen appliances require dedicated circuits: Electric Ranges (Cooking Appliances): Typically, a 240V circuit. Electric Cooktops (Countertop Cooking Appliances): Typically, a 240V circuit. Electric Ovens (Wall-Mounted): Typically, a 240V circuit. Microwave Ovens: NEC 210.23(A)(2) individual branch circuits are required for appliances where the appliance rating is 50% or more of the branch circuit rating. If the microwave rating is above 720W, then a dedicated circuit is required.

Dishwashers: 120V circuit.

Refrigerators: 120V circuit.

Garbage Disposals: 120V circuit.

Countertop Receptacle Outlets: At least two 20-ampere small appliance branch circuits are required to serve receptacle outlets.

Important Considerations



Local Codes

Always check with your local building codes and electrical inspectors, as they may have additional requirements or modifications to the NEC. Local codes always override the NEC.

Appliance Specifications

The specific voltage and amperage requirements for each appliance will be listed on the appliance's nameplate. Always refer to the appliance manufacturer's instructions for proper wiring.

Cord-and-Plug Connected Appliances

For a cord-and-plug connected appliance, the amperage rating of the appliance must not exceed 80% of the branch circuit's rating.
