Which Appliances Need Their Own Dedicated Circuit?

A dedicated circuit is a circuit that serves one appliance and nothing else. It exists so that a power hungry device has all the capacity it needs without tripping breakers or sharing with your lights and outlets. Here are the appliances that typically need one and why.

Why dedicated circuits exist

Large appliances draw a lot of power, especially when they start up. If they share a circuit with other things, you get tripped breakers, dimming lights, and strain on the wiring. A dedicated circuit gives the appliance a clean, correctly sized supply of its own, which is both safer and more reliable.

Appliances that usually need one

A number of common appliances should be on their own circuit. Electric ranges and ovens, clothes dryers, and electric water heaters need dedicated 240 volt circuits. Dishwashers, garbage disposals, microwaves, and refrigerators are usually on their own dedicated circuits too. Furnaces, air conditioners, and well pumps need dedicated circuits. And newer additions like EV chargers and hot tubs always require a dedicated circuit sized to the equipment.

Signs something needs its own circuit

If a breaker trips whenever a certain appliance runs, or your lights dim when the microwave or air conditioner starts, that appliance may be sharing a circuit it should not. Space heaters are a common culprit, since they draw a lot and are often plugged into a circuit already carrying other loads.

Adding a dedicated circuit

Adding a circuit is a routine job for an electrician. We run a new line from your panel to where the appliance lives and size it correctly for the load. If your panel is full, we will talk through options, which may include making room or upgrading.
