These guys weld with 1000A: https://www.youtube.com/watch?v=j61ezBX-EyA https://www.youtube.com/watch?v=j61ezBX-EyA Trucks use that kind of current to start and it doesn't seem to be an issue, though the starting sequence is rather short so it may be counting on the fact that some stuff will not have time to get heated up. I don't want to say you can just put 1000A into existing cables, what I want to say that I can imagine this being manageable with some additional engineering (and especially safety) challenges to be solved.
