hey all...i have a question regarding a 600v/347v generator

first off the generator is apx. 100 amps at 600v..this unit will be installed in a cube van to power a 60a.600v cutting machine. next, this generator will also power a 40a.600v cutting machine. Hopefully my layout is correct

100a 600v disconnect with teck wire#3
splitter
60a 600v disconnect to device using #6 teck wire
40a 600v disconnect to 30kva 480v transformer(auto) #8 teck wire
40a 480v disconnect to device #8 teck wire

please let me know if im missing anything..i do have a question regarding grounding..where do i ground the generator and the transformer...? and is #6 large enough for both the generator and transformer


thanks in advance

I'm not sure Part 1 applies to portable equipment. That might require CSA approval.

A ground plate is probably best. Use a wire long enough that you can drive around town. It makes the job harder to inspect if it keeps moving.

Actually, I don't know how to handle grounding.
