What is a panelboard?

A panelboard is an essential component in an electrical distribution system that houses circuit breakers or fuses. It serves as a central point where electrical power is distributed to various circuits within a building or facility. The panelboard allows for the safe and efficient management of electrical circuits, providing a location to switch individual circuits on or off and provide protection through the use of circuit breakers or fuses. This configuration helps prevent overloads and short circuits by interrupting the flow of electricity when a fault is detected.

The significance of a panelboard lies in its role in maintaining electrical safety and ensuring that electricity is effectively routed to different parts of the system. By having circuit breakers or fuses mounted within the panelboard, the system allows for easy access and control over electrical circuits while ensuring that proper protective measures are in place.

Understanding the function of a panelboard is crucial for anyone studying electrical systems, as it is a fundamental part of managing electrical distribution and ensuring safety in both residential and commercial settings.
