Questions homeowners ask

FAQ

Is a dedicated outlet the same thing?

A dedicated circuit may serve one outlet — the breaker and wire sizing matter as much as the faceplate.

Can my panel support another circuit?

Only if slots and service capacity allow. Sometimes the panel upgrade comes first.

Do refrigerators need dedicated circuits?
