Ok once again I need help. I am down in Texas doing emergency power assesments in support of FEMA operations. However i have had a serious brain lapse in the last few hours and cant for the life of me figure this out. I have to size generators for a few E.O.C.s running out of office buildings. What generator voltage do i need to request in order to go straight into the panel box and heat up lighting and a/c's. i need 110/208 but i cant get a 3 phase generator that produces 110/208 and hook it up to the panel can i? So i guess what i need is a single phase, 110/220 3 wire generator right. please help i need to get this straight in my head.
