A bus bar, commonly available at major home improvement retailers, including The Home Depot, is a metallic strip or bar, typically made of copper or aluminum, that serves as a central point for electrical connections. It efficiently distributes high currents between multiple circuits within an electrical system. For example, in a residential electrical panel, a main bus bar distributes power from the utility feed to individual circuit breakers serving various appliances and lighting throughout the house.
The implementation of this component is essential for maintaining a safe and organized electrical system. It simplifies wiring, reduces the risk of loose connections, and provides a reliable pathway for electricity to flow. Historically, bus bars have been employed in industrial settings for decades, but their application has expanded into residential and commercial buildings due to increased electrical demands and safety regulations.
