Frequently Asked Questions

What is the purpose of a busbar?

The purpose of a busbar is for collecting electric power from an incoming feeder and distributing that power to outgoing tap-offs. The first and foremost main purpose is to carry electricity and distribute it. They are essentially used to make a system more efficient.

What is a busbar in an electrical panel?

In an electrical panel, a busbar is a rigid conductor used for connecting together several circuits. Busbars in electrical panels are usually made from copper.

How is a busbar utilised in a package substation?

A busbar is an element you will find housed inside switchgear, panel boards and busway enclosures for local high-current power distribution. When package substations are required, the transformer within can be connected directly to the main LV switchgear via high-powered busbar systems that are manufactured in either aluminium or copper. The maximum rating for the busbar in these cases is 6300A.

Why is aluminium used in busbar systems instead of copper?

Aluminium is lighter in weight when compared with copper as aluminium has a lower density than copper (approximately 70% less). This makes it a viable option for busbars, when conductor size is not a problem. Although copper is a superior conductor to aluminium, aluminium conductors are cheaper to manufacture and buy, so for certain projects where cost is key, aluminium busbar systems are a popular choice. NOTE: Aluminium busbars are never used in AF Switchgear assemblies.
