I have a question. Does the N.E.C allow splicing in LBs, can it be used as a general purpose junction box?
If yes, then I would call this "use of an LB as a juction box". This would bring up issues of internal box volume and maximum box fill. Removing the cover would probably reveal a code violation in these areas.
If No, then I would call this "modification of electrical equipment".(modifying a 2"LB to a 2"LB,LL3/4")
Does the N.E.C allow modification of electrical equipment without it being re-certified?
