Appliances that need their own dedicated circuits
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.
