If your inspector is on his toes he will say something about feeding a pool/spa panel with SER. Check NEC 680.25 '02 Edition. Don't know the exact reason why it's safe if it's existing but it's dangerous if installed new but that's what the words are saying.
I would be moving the pool and spa panel to the new service equipment location. It would be supplied through Flexible metallic Conduit from the meter cans terminal studs via 250 MCM Al service entry conductors. It's main breaker would be one of two service disconnecting means. The other would be the main breaker of the lighting and appliance (L&A) panel board that serves all of the homes other loads. I will convert the L&A panel to Main Lug Only (MLO) and install its main breaker in a breaker enclosure right beside the pool and spa panel at the location of the new meter can. Both the pool and spa panel and the L&A main breaker enclosure will be nippled from the back of the meter can. The existing feeder to the pool equipment panel runs right past that new service equipment location so all I will have to do is to shorten it. The new feeder that will supply the L&P panel from the main breaker enclosure at the new service equipment location will temporarily supply the pool and spa panel from the existing service location that the POCO now finds so unacceptable. If that is the use of SER cable that you think that AHJ staff will find objectionable then I just have to hope that they will accept it until cut over to the new meter when all will be well once again.
