What is a dedicated circuit and when do I need one?

A dedicated circuit serves only one appliance or device and is not shared with any other outlets. The National Electrical Code requires dedicated circuits for major appliances like refrigerators, dishwashers, garbage disposals, microwave ovens, electric ranges, water heaters, washers, dryers, HVAC systems, and garage outlets. Dedicated circuits prevent overloads and ensure reliable operation of critical appliances.

Why It Matters

Shared circuits with major appliances can trip breakers at the worst times and create fire hazards. Dedicated circuits are code-required for good reason.
