motor generator set

[bbanzai]

Can anyone give me some guidance on sizing service conductors for a 150 hp 3 phase/delta motor generator? The m/g set provides power to a communication site. Do I size from the motor table and the 1.25 rule?

I would suggest that the supply conductors be sized per 430.22 and the output conductors per 445.13.

Thanks, That is what I did. I used table 430.150 and did it just like it was a feeder circuit. Thanks for the help.
