702.5(B)(2)(a)

I have a 200 amp panel with 200 amp main OCPD and a calculated load of 160 amps. According to Art.702.5(B)(2)(a) 2008 NEC. I would need a Gen. large enough to carry the 160 amp load. Am I reading this correctly?

Yes, unless you got one of those fancy 'load shedding panels'

thanx. I thought so, someone on the jobsite seemed to think that the gen. had to be capable of handling the entire 200 amp panel because of the 200 amp main breaker.

If you are using a automatic transfer switch then yes it must be sized to the load unless you do load shedding. If it were a manual transfer switch then it would not have to be sized for the full load. Or you could install a sub panel to supply your needed circutes and size it to that calculated load.

Thanx for your help, I have a better understanding of what is required.
