1/8th copper or 4mm stainless steel for busbar?

[Poey50]

A quick plug for Ox-gard. Said to be good at inhibiting corrosion and is itself a conductor. I've used it originally for a junction of copper busbar to aluminium lithium cell terminal and now on all major connections. Time will tell. Under a tenner for a small tube.

Hi have a look at the Furneaux Riddall website they have a selection of studs / busbars and joiners rated at 650 amps which may be of use.

I'm planning to join 3 x 12v battery negatives wires using a simple busbar. Of the 3 cables, the biggest is 95mm2, the other is 75mm2. My choices of readily available material is either 1/8th x 1 inch copper strip or 4mm x 25 stainless steel strip. I'm also planning to use M10 stainless steel bolts with locking washer to clamp everything together.

Which material would make the better busbar?

and also the 12 volt planett website
I found some nice 3 stud busbars on there that would be ideal ... but expensive. With only 3 cables a power-stud would be an acceptable and much cheaper option

For a decent quality job either of these should be mounted somewhere suitable and new cables made to suit the position. Anything dangling in the wiring is a badge , imo.

As its only 3 lugs a standoff insulators with all 3 lugs bolted down would do the job. Drop me a PM and I will sort one out for you.

Thanks, Vic, I’m not an electrical engineer (evidently) but rest assured that there will be no bodge jobs on my boat. She's now 7 years old and this is how I keep the engine bay
