Why Your Major Appliances Need a Dedicated Circuit

dedicated circuitMost older houses do not have an electrical system with dedicated circuits. However, if you are renovating, adding a room to your house or building a new home, it is recommended to put in dedicated circuits for all of your major appliances. The National Electric Code stipulates that most appliances should have a dedicated circuit.

What is a Dedicated Circuit?

A dedicated circuit is any electrical circuit from your circuit breaker that is used for a single specific purpose, appliance or tool. A dedicated circuit will prevent more current to be drawn from what your circuit breaker can handle. Blown fuses, tripping of breakers, and overheating wire insulation are generally the result of a single circuit serving several appliances. When this happens, the circuit breaks down and may start the possibility of electrical fires or electrical failure.

What Needs a Dedicated Circuit

Appliances that use large amounts of power require a dedicated circuit. These include the following:

  • Refrigerators
  • Stand-alone or portable freezers
  • Ranges and ovens
  • Dishwashers
  • Microwaves
  • Washers and dryers
  • Hot tubs and other similar fixtures
  • Heating and cooling equipment
  • Garbage disposals
  • Sump pumps


It is also highly recommended to have at least one outlet for every floor of your home that is connected to a dedicated circuit. This is specifically convenient and safer when operating high-drawn portable equipment. Having dedicated outlets to power vacuum cleaners, blow dryers, space heaters, and other occasionally-used electrical items prevent breaker trips, as well decreases the risk of flickering lights.

Appliances that are connected to a dedicated circuit but with an inaccurate wire size and inadequate amperage than they require may result to overheating that can possibly result in a fire. So make sure that you hire an electrician Columbus Ohio, who has been tested for their competency and professionalism.

If you have been experiencing frequent trips from one or more circuit breakers, they are telling you to invest on a dedicated circuit for your appliances. If this is happening, look for a pattern – if it trips when using your microwave and toaster at the same time, it is a warning sign that the power supply line it uses is experiencing weakness of power.

Bear in mind that it is better to have several dedicated circuits rather than not having enough.

Tip: An appliance that runs with its own motor and is used regularly in one place needs a dedicated circuit.
