In this circuit diagram, what gauge cable does the green wire marked “GND” from the Linx distributer need to be relative to the various other cables?
Also, why?
It has to be the equal to or larger than current conductors as it has to be able to carry the full fault current of the system as far as I understand.
So equal or thicker than the battery cables to the Lynx BMS?
I‘m confused as to why that would be necessary. The full fault current is surely only in the battery circuit, and with fuses everywhere, what are we trying to achieve by also giving that path to ground?
If I run a cable from an isolated battery positive terminal direct to earth, nothing will happen so what is the advantage of lining the negative to earth with such a large cable?
I find DC earthing very confusing…
