I know that this may have been covered before, in some way, but here is my situation:
I am to install a 400 amp single phase service on a commercial building
the customer wants a transfer switch and will be setting a permanent generator.
I am planning to install a full size (400a) transfer switch
Due to space restrictions, I am hoping to use the transfer switch as the service disconnect, and install a main breaker panel close to it. (by close, I mean within 10 feet on the same wall. Definitely within sight)
the transfer switches that I have been quoted are shown as 'service equipment', however, our state inspector indicated to me (in a brief conversation) that I needed to set a disconnect ahead of the transfer switch
I have found several references on line showing a transfer used as service disco when installed 'immediately adjacent' to a main breaker panel
however none of it cited any code sections.
would anyone be willing to cite me the appropriate code sections (2005, 2008 or 2011) that apply to this situation?
Also any additional advice would be great. Im designing this on the fly and dont want to miss anything
thank you
