Blue Bar 7 Stud M6 Busbar 150A with Clear Cover – Red, Black or Pair

This 7 stud M6 busbar packs seven connection points into a compact 150mm bar. That’s a main feed plus six circuits, all landing in one tidy spot instead of stacked on a battery post or chassis earth. It’s rated to 150A, uses M6 studs to suit the smaller lugs common on accessory wiring, and comes in red for positive, black for negative, or as a matched pair. The clear push-on cover keeps the live studs covered while letting you check every connection at a glance.

Specifications

What the M6 busbar suits

• Dual battery systems in 4WDs and utes
• Caravan, camper trailer and motorhome 12V wiring
• Multi-circuit accessory distribution for lights, fridges, USB and 12V outlets
• Canopy and drawer system power builds
• Common negative points so earths aren’t stacked on the battery or chassis

Fuse each outgoing circuit to suit its cable. A busbar distributes power but doesn’t protect it.

Built to spec. Made for the track.

Frequently asked questions

What is a 7 stud M6 busbar used for?

A 7 stud M6 busbar gives you one common connection point for up to seven cables, so you aren’t stacking lugs on a battery post. It suits builds with lots of accessory circuits, keeping dual battery, caravan and 4WD wiring tidy and easy to trace.

What size cable lugs fit this busbar?

It takes lugs with an M6 (6mm) hole. Choose the lug barrel to match your cable size; the stud size stays the same.

What’s the current rating?

The busbar is rated to 150A. Each outgoing circuit should still be fused to suit its own cable size.

Can I use it on a 24V system?

Yes. It’s rated to 48V DC maximum, so it suits both 12V and 24V systems.

What’s the difference between the 7 stud and 6 stud M6 busbars?

The 7 stud gives you one extra connection point on the same 150mm base. Both are rated to 150A and use M6 studs; the 6 stud has slightly more room between studs.

What’s the difference between the red and black versions?

Red is for positive (+) distribution and black is for negative (−). Most new setups need one of each, which is why we also sell them as a matched pair.
