Customer wants to be able to cross connect between 2 1000 A 3 phase, 480 V generators to be able to operate in case of catastrophic generator failure. All load are 3 phase delta connected. 200HP load is softstart.

Is there any requirement to carry a neutral conductor(s) (NEC or MSHA), or can I just carry 3 conductors and EGC?

Thanks for help!
