What is the function of a busbar in an electrical panel?

A busbar serves as a conductive pathway that distributes electricity within an electrical panel. It is typically made of metal, such as copper or aluminum, and is designed to handle high electrical currents. The busbar connects various circuit breakers or fuses, allowing for the efficient distribution of electrical power to different circuits or loads within a system. By providing a centralized point for electrical distribution, it simplifies the wiring and enhances the overall reliability and performance of the electrical panel. Additionally, busbars can help minimize power losses and improve safety by reducing the risk of overheating in wiring connections.
