George:

"(2) Automatic Transfer Equipment. Where automatic transfer equipment is used, an optional standby system shall comply with (2)(a) or (2)(b).
(a) Full Load. The standby source shall be capable of supplying the full load that is transferred by the automatic transfer equipment.
(b) Load Management. Where a system is employed that will automatically manage the connected load, the standby source shall have a capacity sufficient to supply the maximum load that will be connected by the load management system. "

Could you not define (a) as the actual load, documented by POCO info (billing), or data from a recorder device?

Most resi gens & xfr switches that I have seen go to a 'sub or 'gen' panel, thru the transfer switch, so the load in the gen/sub panel with a xx amp 'main' to 'match' the OCP on the gen.
