Hi Marco:
You are correct, I have noticed that most LBs do limit the fill area of
your
conduit. As you probably notice, making a 90 bend requires some extra area,
especially for large conductors. This is one good reason to not fill the
conduits to maximum capacity. Most LBs and other boxes do list the area of the
box on it. If you are not sure, you should perform a calculation to determine
how much of the total area you are consuming, based upon NEC requirements.

Subject: [RE-wrenches] Aluminum conduit LBs
Anyone know where I could go to find out the max conductor sizes that threaded
Al. LBs can handle?
I learned the hard way that a conduit of X inches that can handle conductors of
a certain size does not necessarily mean that a LB of the same diameter can
handle the same size conductors.
Thanks,
marco
