A compact 150A 12V bus bar for tidy power and earth distribution in 4WDs, caravans, campers and boats.

Rated 150A DC, up to 48V DC
Tin-plated copper bus, clear cover and hardware included




Red (positive) or black (negative) base


12V Bus Bar 2 x M6 Studs, 6 Screw Terminals
This 12V bus bar gives you one clean, common connection point instead of a stack of lugs crammed onto a battery terminal. Bring your main positive or earth cable in on one of the M6 end studs, then run up to six smaller circuits off the M4 screw terminals — lights, fridge, USB outlets, radio, compressor feeds and the like. Rated to 150A DC, it suits 12V and 24V systems in 4WDs, utes, caravans, campers and boats.
Choose a red base for positive distribution or black for a negative/earth bus — or run one of each for a neat, colour-coded auxiliary setup.

══════════ FAQ (on-page) ══════════
Q: What is a 12V bus bar used for?
A: A 12V bus bar joins several circuits to one common positive or negative connection point. It keeps wiring tidy and stops you stacking multiple lugs on a battery terminal.
Q: What current is this bus bar rated for?
A: This bus bar is rated to 150A DC. Your main feed cable, fuse and total connected load should all sit within that rating.
Q: What size terminals does it have?
A: It has 2 x M6 studs and 6 x M4 screw terminals. The M6 studs take your main feed or larger cables on lugs, and the M4 screws take smaller branch circuits on ring or fork terminals.
Q: Does it work on 24V systems?
A: Yes, it suits 12V and 24V DC systems, with a maximum rating of 48V DC.
Q: Should I use red or black?
A: Use red for positive distribution and black for negative or earth. Many setups use one of each for clear, colour-coded wiring.
Q: Does it come with a cover?
A: Yes, it comes with a clear protective cover held in place by two black cap nuts. The cover helps prevent accidental shorts while letting you see the connections.
Q: What is the bus bar made from?
A: The bus is tin-plated copper, which conducts well and resists corrosion. It sits on an insulated base and comes with a clear cover and hardware.
