What is a bus bar used for in an aircraft electrical system?

A bus bar in an aircraft electrical system plays a crucial role in the effective distribution of electrical power. It serves as a conductor that facilitates the flow of electricity from the power source to various systems and components throughout the aircraft. This central point of distribution allows for organized and efficient routing of power, ensuring that all systems receive the necessary electrical supply without requiring individual wiring for each component. This not only simplifies the electrical architecture of the aircraft but also enhances reliability and maintainability. By using bus bars, aircraft designers can manage electrical loads more effectively, which is vital for the smooth operation of avionics, lighting, and other critical systems on board.
