<strong>Why You Need a Dedicated Circuit for Appliances</strong>

Do you trip a circuit breaker when you turn on your toaster or use your hair dryer? If this is a common occurrence, it could indicate either appliance is not receiving adequate power to safely operate without overloading your home’s electrical system.

The NEC (National Electric Code) requires that every major appliance, such as dryers, refrigerators, stoves, and washers, has its own dedicated circuit.

An appliance equipped with a dedicated circuit will have its own circuit breaker in your home’s electrical panel. There should be no other appliance using electricity from this circuit because it is only “dedicated” to this appliance.

Dedicated circuits are installed to help make sure every major appliance has the power required for functioning properly and will not be overloading the electrical system.

Dedicated Circuits and Safety

If several large appliances are sharing a single source of power, a circuit may be drawing more electricity than it can safely handle. This can lead to tripped breakers or blown fuses.

When an appliance is connected to a dedicated circuit with the wrong wire size or insufficient amperage, it can result in overheating and lead to an electrical fire. Wiring  appliances safely and correctly is important for the safety of your family.

Frequently Tripping Circuit Breakers

If your circuit breakers are frequently tripping, it is probably a sign your home needs the installation of a dedicated circuit. As stated by the NEC, every fixed appliance requires its own dedicated circuit. In addition, an appliance equipped with a motor typically needs to have a dedicated circuit.
