I'll probably get some abuse for this but it is my belief that the BS series is a thread size and so may only be related to the hole in the swaged terminals.
I'd be more interested in knowing the diameter or cross-section of the conductor to judge whether it will carry the amperage you need.
a bit over priced. Go to a welding repair shop and get some 25 or 35mm2 cable , they will cut it to length and fit the lugs. From memory it's about $10/metre and lugs are $2.5 each.
That 390 amps is intermittent current carrying capacity. They should quote a duty cycle as well.
It's just like those 200A jumper leads you buy for $10.
12mm is only good for about 55A continuous.
The current that it can carry is also dependent upon the length of the cable and how it is fixed or laid.
If you don't want to buy rubbish for the boat then get some tinned welder cable in the 35mm or bigger.
Be carefull with those leads from bias or whitworths or supercheap or anywhere. Make sure they're tinned cable and the terminations are soldered as well as crimped. Not just crimped.
Good to have the resin filled heatshrink used as well.
Personally I wouldn't use those leads on the ride-on. But I'm a tad fussy I've been told.
Busbars cannot bend like a battery cable and are mainly made of copper.
Out of interest I'll bung my flash ammeter on Wally the wagon and see what current is drawn by a starter in a 4 cylinder car.
Might be an eye opener on the current a starter draws.
Un beleavable somone has already flogged the old bus bars.
Yeah you right there replacing with copper ones the original looked like brass maybe that's just there age showing and dulling.
They used to use a lot of brass and bronze here 20 grand for a bronze light pole Huh then they paint it red go figure.
Guess I should have tried to polish some of them before they turned the power off, always next year.
It appears that I will be looking for some as well, the person who had my boat before me put a part of my battery cable through a bulkhead below the floor and the rubber hose he used for insulating slipped off, resulting in the aluminium wearing through the insulating rubber of the cable.
And here was me wondering if I had a voltage leak in the wiring!
Why don't they just size in mm now??
That'll keep everything standard.
There's at least 4 different ways to size cable.
There's normal cross sectional area as used by the domestic/commercial type wires in the home and factory.
There's automotive metric sizing (and I'm buggered to understand how they work it out)
There's BS (I won't say what I think of that but it's initials are similar to the name)
And there's AWG.
If your like me your probably very confused about now
