Hi,
Is it allowed to make joints in LB fittings?

I could be wrong,but I think as long as it meets the cu in box fill requirement It may be allowed.I would never splice service conductors though.
between meter and service disconnect that is. smile

I think it is something to be avoided. There is no provision for bonding in an LB, it is difficult to maintain 150mm of conductors for splicing, and some may consider an LB to be a raceway, and we know joints are not permitted within raceways.That being said I dont think there is a rule that specifically prohibits splicing in an LB.

If the conduit body has a cubic inch area marked on it then you can splice in it according to 12-3034

My reading of 12-3034 is that it refers to boxes, whereas an LB would be considered a fitting - so should 12-3034 apply?

Just a little insight from the NEC Standpoint:

314.16 (c) 2011 NEC

(2) With Splices, Taps, or Devices. Only those conduit
bodies that are durably and legibly marked by the manufacturer
with their volume shall be permitted to contain
splices, taps, or devices. The maximum number of conductors
shall be calculated in accordance with 314.16(B). Conduit
bodies shall be supported in a rigid and secure manner.

IMHO, splicing within an LB, LL, LR, C, T, etc. is not a respected trade practice, and not often seen.
