The role of a distribution panel is to distribute electrical power and protect circuits. This panel acts as the central hub for incoming electricity and directs it to various circuits within a building or structure. It contains circuit breakers or fuses that protect the circuits by automatically shutting off power in the event of overloads or short circuits, thus ensuring safety and preventing damage to the electrical system.

Distribution panels are designed to manage and organize electrical distribution efficiently, allowing for the distribution of power throughout an entire facility while also providing a means to isolate and protect individual circuits. This makes it an essential component of any electrical system, as it not only ensures that power is effectively routed to where it is needed but also serves a critical safety function by providing protection against electrical faults.
