Ampacity of Power Buss?

[Erik Jenkinson]

I'm installing a (24V) inverter in the back of my M1009. I plan to run 1/0 welding cable to replace th (2AWG) heading to the buss bars in the back. I will power the inverter from there. This left me to wonder, How much current can our bus bars handle safely? I suppose if nobody knows right off the top of thier head, I will just measure the bus and calculate it?

I was going to suggest measuring the busbar to calculate it after reading the title

I recently took the busbar apart. There's a copper strip/flat bar connecting the studs. It would be easy to make yourself a thicker one if needed.
