Hi,
I'm looking for a bus bar to use for the negative side of my camper van 12v system.
The ones I am looking at seem to be rated for 250A, but each individual stud is only rated for 62.5A. As one stud will be connected to my shunt and then battery does this not mean that the whole bus bar is limited to 62.5A as the current would be directed via the one stud?
Here is the one |I was looking at. Many seem similar though and list overall current limit and individual stud limits.
My battery only has a 100A BMS so thats the most I could draw, but it is still greater than the 62.5A rating of one stud.
