Common Bus Bars

A bus bar is a conductive strip—typically made from copper or brass—used to distribute electrical power within a system, reducing wiring complexity and improving reliability. In camper van applications, common bus bars are most often used for negative (ground) distribution, helping to centralise connections and eliminate messy wiring runs. This not only improves the appearance of your installation but also enhances safety and makes troubleshooting easier.

The Wired Campers range includes a variety of options such as 5-way, 10-way and 12-way common negative bus bars, typically rated up to 100A or 150A for standard 12V systems. These multi-terminal designs allow you to connect multiple circuits—such as lighting, USB sockets, water pumps and appliances—to a single grounding point, simplifying your overall wiring layout. Many models also include protective covers to prevent accidental short circuits and improve safety.

For higher power applications, heavy-duty bus bars rated up to 300A are available, featuring large M8 stud terminals for connecting inverters, battery banks and high-current charging systems. These are ideal for more advanced camper van builds with lithium batteries, DC-DC chargers and off-grid power systems.

Premium options from trusted brands like Victron Energy, including the Lynx distribution system, offer modular bus bar solutions with integrated monitoring and expansion capabilities. These systems are designed for high-end camper van electrical setups where performance, scalability and reliability are critical.
