Bus ducts and bus trunking are essential components in electrical power distribution systems, providing a reliable and efficient means of transporting electrical power from the main switchgear to various distribution points within a building or industrial facility. Here’s an overview of bus ducts and bus trunking, their current state, and potential future developments Bus ducts and bus trunking consist of a series of conductors enclosed in a protective housing, typically made of metal or insulated material. The conductors carry electrical power from the main switchgear to distribution panels, motor control centers, or other load centers, providing a high-capacity and low-impedance path for power transmission.
