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 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 rated to 48V DC maximum, so it suits both 12V and 24V systems.
What 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.

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.
