IRC E3904.5 does state that typical outlet boxes are allowed to support fixtures that weigh up to 50 pounds. The outlet boxes need to be listed and correctly installed, with adequate attachment to framing members ... or that chandelier may end up on the dinning room table ... ![icon_eek.gif](upload://yuxgmvDDEGIQPAyP9sRnK0D0CCY.gif)
Per the IRC any fixture that weighs over 50 pounds needs independent support ... and that probably should be designed by a professional.
Hope that helps.
