Quick Tip: What is a Busbar?

If you work in power distribution, you might be familiar with the subject of this GalcoTV quick tip. Today, we’ll answer the question: “What is an electrical busbar?”

As the name implies, a busbar is a metallic bar constructed with conducting material like cooper or aluminum, that is found in a switchgear panel. It serves as an electrical junction that aids in the flowing of incoming and outgoing current. Busbars are commonly used over cable connections because of their installation flexibility, heat resistant capabilities and the fact they can absorb heat better. Because of this, they provide a reliable and cost-effective solution in even the most complicated electrical systems.

You can construct three main types of busbar systems:

• Single Busbar
• Double Busbar
• Ring Busbar

Each system provides distinct advantages and disadvantages over the other, depending on your application needs.
