The comprehensive guide titled “Busbars: Design and installation of low voltage busbar trunking systems,” available on the Electrical Engineering Portal, presents a valuable resource for understanding the intricacies of designing, installing, and safely utilizing busbar trunking systems. This guide serves as an easily comprehensible document that assists in interpreting the specific requirements associated with the design, installation, and operational use of these systems.

The primary application of busbar trunking systems is the distribution of power over predefined areas, serving as a vital infrastructure for diverse settings. These systems can be installed either vertically, horizontally, or in a combination of both orientations, offering flexibility in their deployment. The guide outlines two main types of trunking runs:

1. Distribution Trunking Run: This is the most prevalent application of busbar trunking. It involves distributing power across predetermined areas. These trunking runs can serve various purposes, such as supplying power to a large number of light fittings, facilitating power distribution in industrial and office settings, and functioning as rising mains in office or apartment buildings. These rising mains supply distribution boards serving individual floors or other busbar systems catering to different floors.

2. Feeder Trunking Run: Feeder trunking runs serve as interconnections between switchboards or between a switchboard and a transformer. These runs play a crucial role in ensuring efficient power flow and distribution within electrical systems.
