I am installing a 3-gang meter socket/disconnect for (2) offices and (1) apartment. I am going to exit through the bottom of the meter socket with the 3 SE-R?s and then through a brick wall into the basement. In order to provide protection to the cables and a more professional looking installation I would like to use sch80 and an LB, basically as a sleeve for the SE-R. Under 230.50 I see no code violation here, but I am unable to find anything on the sizing of the conduit. Also this method would eliminate the use of a SE connector at the entry of the meter socket and I am unsure of how to legally secure the cables.

Any suggestions would be greatly appreciated.
 
I would not use the LB's. It's not possible to keep the proper bending radius of 5X the cable diameter of the SER within the condulet. You should consider elbows if you have adequate room for the sweep. Look at 338.24.
 
Good call Trevor, yet I see this one done all the time, and passed. Mike12347, is there enough clearance to put a gutter under the sockets, and nipple both up and out the back?

312.5 Cabinets, Cutout Boxes, and Meter Socket Enclosures.
Conductors entering enclosures within the scope of
this article shall be protected from abrasion and shall comply
with 312.5(A) through (C).

(C) Cables. Where cable is used, each cable shall be secured
to the cabinet, cutout box, or meter socket enclosure.
Exception: Cables with entirely nonmetallic sheaths shall
be permitted to enter the top of a surface-mounted enclosure
through one or more nonflexible raceways not less
than 450 mm (18 in.) and not more than 3.0 m (10 ft) in
length, provided all of the following conditions are met:
(a) Each cable is fastened within 300 mm (12 in.),


What am I missing??

Excellent point infinity.

Macmikeman, I don?t see any clearance issues and I like your suggestion, but how could I make this meet the requirements of 312.5 ( C ) As cpal has listed below the exception for 312.5 ( C ) is for cables entering the top of an enclosure.

My thinking a gutter is not a cabinet,cutout box or meter socket enclosure so therefore 312.5 would not apply to it. Splice the ser to thhn conductors inside the gutter. The thhn conductors go up thru the nipples into the meter socket/disconect switch. Key here is the conductors must be downstream of the disconect switch, and not service conductors. Gutter fill and conduit entry / gutter size requirements will now apply.
