At A Code Update Class We Were told that A Condulette is only rated for 25% Fill, And I've seen the markings on LB's that State the maximum wire size and Quantity being far less than 40%, But I've Never Seen it in the NEC. Is it NEC or UL?
Same thing with Exp proof Seals. If you order a seal Rated for 40% fill they send you the next trade size larger and 2 reducing bushings.
This probably wont change for a long time, As the Code making panel is busy with alot more serious issues. A wire shorting in a LB is unlikely to cause injury or damage to a structure.
