10-Way Negative Bus Bar (Black) – 150A Continuous | Safety Cover & Screws Included

10-Way Negative Bus Bar (Black) – Clean, Safe & Reliable Power Distribution

The 4x4LAB 10-Way Negative Bus Bar is the clean, professional way to manage earth connections in your 12V or 24V setup. Designed for 4WDs, campervans, caravans, boats and off-grid power systems, this busbar keeps your wiring organised, accessible and protected, even in harsh Australian conditions.

With 10 dedicated negative terminals, a clear safety cover, and a 150A continuous current rating, this bus bar makes grounding multiple circuits simple and reliable. Whether you’re wiring accessories, solar, DC-DC chargers or Starlink Mini, this is a rock-solid foundation for any electrical system.

Unlike many alternatives, 4x4LAB includes the mounting screws, so it’s ready to install straight out of the box.

Why Use a Negative Bus Bar?

Using a negative bus bar reduces wiring clutter, simplifies fault-finding, and improves overall system safety. Instead of stacking multiple cables on a single battery terminal, each circuit gets its own dedicated connection point, clean, logical, and service-friendly.

The insulated base and clear safety cover help prevent accidental short circuits, making it ideal for tight installs in drawers, power boxes and under-seat setups.
