Are regular ceiling boxes that are sold today rated for fixtures weighing over 40 lbs? I'm not talking fans, just fixtures. (i.e) carlon boxes, metal pan boxes. etc. Ref NEC 2011 314.27 (A) (2)

I believe the round boxes are rated for 50 pounds. Would I hang a chandelier on a plastic round box-- I don't think so but I do believe they are rated for it.

This is from Carlon FAQ and is interesting

How heavy of a light fixture or ceiling fixture can a listed ceiling box

support?

A ceiling box can support a fixture of 50 pounds or less. A ceiling box rated for

"fan support" can support a fan of 35 pounds or less.
