What is the primary function of an electrical panel?

The primary function of an electrical panel is to distribute and manage electrical power to various circuits. An electrical panel, commonly known as a breaker panel or distribution board, serves as the central hub within an electrical system. It receives electrical power from the utility supply and distributes it to different circuits throughout a building or facility. This distribution is accomplished through circuit breakers or fuses that protect the circuits from overloads, ensuring safety and reliability in electrical installations.

By managing how power is routed to the different areas of a building, the electrical panel plays a crucial role in maintaining the proper operation and safety of electrical systems. It also allows for the isolation of individual circuits for maintenance or troubleshooting without shutting down the entire electrical system. Understanding the function of the electrical panel is fundamental for anyone involved in electrical installation and maintenance, as it directly impacts how electricity is safely utilized in various applications.
