Hello. Is it feasible for a 2" LB connector to provide a large enough bend radius to meet NEC bend limits for a 1/0 cable? I've got a situation where 1/0 cable running 600 V of DC power from a solar power system is being fed over a roof parapet and down two stories through a 2" conduit that is bent 90 degrees with an LB connector. I'm wondering if that meets code. Thank you.
 
Can you better describe your "1/0 cable" ?
are you speaking single conductor or muticonductor cable ?
In either event, how many conductors ?

It's a single conductor, 1/0 THHW. Thanks. (Sorry for the delay. Was on vacation).

There's no NEC requirement for single conductor minimum bend radius. However, the conductor manufacturer may have one...

Since it is very unlikely that the distance between the conduit entries in the LB meets the rule 6x in 314.28(A)(2), you have to look to the making on the fitting as to the maximum size and number of conductors permitted to be installed in that LB. 314.28(A)(3)
