Why is circuitry important in a new home?
Planning kitchen circuitry is a critical step when designing a new home because stoves, refrigerators, microwaves, toasters and coffee makers draw significant amounts of electricity. In older homes built before the introduction of today’s advanced appliances, a single circuit was usually adequate to service all of a kitchen’s electrical needs. But when several modern cooking devices are used at once, it may cause the circuit breaker to trip. One way to eliminate that risk is to set up a separate circuit for the refrigerator.
What is the wattage of a refrigerator?
