appliances that need their own dedicated circuit

Appliances are more and more sophisticated today .  they come with  features and options that are just difficult to ignore. But they have a cost. not only during the  purchase, but also later in the electrical system. Your control panel might not handle the appliance that you just bought and got bad . A direct consequence to this, is a circuit  overload which can creates an electrical fire.

what do you understand by a dedicated circuit?

A dedicated circuit is a circuit that is used to only serves one appliance or equipment. They are  commonly used for  appliances that have a motor . The national electrical code  requires that any appliance declared as critical-use needs its one circuit.
Why do my appliances need their own  dedicated circuits
 As I said earlier, dedicated circuits are most of the time used by appliances that have motor. A motor needs a certain power to start up and when that one is not available,  it will consume more current to compensate the mechanical force that is applied. By doing so, that appliance might easily reach the maximum amperage of the circuit breaker and if another appliance was served by the same circuit breaker, it will trips.
Dedicated circuits are also needed to avoid overloading. When many electrical fixtures and appliances are served by the same circuit breaker, an overload can occur.
Critical in use appliances include refrigerators, furnaces or water heaters.
Appliances that need their own dedicated circuits:
Next time that you will make a purchase, carefully think about these following appliances:
  • Microwave ovens: Microwaves ovens became popular in the 1970s. they brought new level of convenience to homeowners. Microwaves need a dedicated circuit simply because they use huge amount of energy for cooking.
  • Refrigerator
  • Air conditioner
  • Freezer
  • Dishwasher
  • Electric water heater
  • Furnace (also heat pump)
  • Bathroom heater (including vent-fan heater units)
  • Garbage disposal
  • Sump pump
All these previous appliances consume huge amount of power . for some of them, like an electrical water heater for example a permit may be needed for installation.
It is also important to differentiate between dedicated and designated circuits. While a dedicated circuit is used when a circuit breaker serves only one appliance, a designated circuit in another hand is used with 02 appliances. Most of the time, designated circuits are those found in laundry rooms. in this case, one outlet circuit is used for both washer and dryer, in case of a gas dryer.
