... I'm starting a good job,where the H.O. wants me to move the service to the other side of the house..(had to ask the PoCo inspector,..but he said it's OK)as well as upgrade to 200amps..AND wire the newly installed central A/C system..At first,I was gonna bus all the existing home-runs to the new panel location,...then I had an "Epiphany"...or a moment of "clarity"..Why can't I just install a main-lug panel,run 100 amp.SER, and use it as a sub-panel..Sounds easier,and cheaper than running all the home-runs over to the new panel...Does this make sense..??

Done all the time out here Russ..... Typically a "blank" will be out in the old meter socket.. Backfeed the bus with a breaker of proper rating for the panel & the feeders you will use & reconnect to a breaker at the new service..

With that distance, it's the best option.
Good Idea !
you will still need a main breaker in the sub panel enless the main panel is in sight of it.

You do? Where does it say that?

Sounds like a good idea provided existing panel is worth saving. You probably already know that you won't need a main breaker in the sub panel. What table will you use to size the feeder?
Article 230 chapter seven {230.91}
"The service overcurrent device shall be an integral part of the service disconnecting means or shall be located immediately adjacent thereto."
But we are talking about {feeders} to the sub panel.
I'm just thinking the sub. still needs a disconect right? because the main isn't with in sight and 50'.
use table 310.15 {b}{6} for sizeing.
Kody, look up the code definition of a "service" and you will see why the article you referenced does not apply to the subpanel in the case discussed.
…and I’m not even going to get into 310.15(B)(6). If the code making panel is going to do such a half-azzed job of explaining its position, then we as electricians should not be expected to read their collective mind.
I agree with Triple, and as for 310.15(B)(6), that is not for the panels past the service equipment. Size the conductors from 310.16 (table).
The definition of service is in Art 100.

So no need for a disconect at the sub panel thats not in sight and 50'?
