Circuit panels, also known as electrical panels or breaker panels, are essential components in electrical systems. They distribute electricity from the main supply to various circuits throughout a building. Each circuit is protected by a circuit breaker, which automatically shuts off power in case of overload or short circuit, ensuring safety. These panels typically contain a metal enclosure that houses the circuit breakers and wiring connections. They are usually mounted on walls in basements, garages, or utility rooms. Proper installation and maintenance of circuit panels are crucial for the efficient and safe operation of electrical systems in homes and commercial buildings.
