Busbar trunking, also known as a busbar system, is a modular power distribution system. It encases metal conductors such as copper or aluminum busbars in a protective housing and assembles them as a complete unit, efficiently delivering electricity from a source like a transformer or main distribution panel to where it is needed.

Inside a busbar trunking system, current flows through rigid conductors called busbars, which are installed within a metal enclosure. The enclosure provides insulation and protection, preventing contact with people and reducing the impact of external dust and moisture, making power use safer and more stable.

Busbar trunking serves as a centralized path that transmits large amounts of power from the main power source to various distribution points within a facility, distributing electricity safely, efficiently, and reliably within the electrical system.
