Hi guys, I'm preparing a new proposal for the above NEC section. There seem's to be a problem with the language. The present 2011 NEC state's the following:
Boxes used at luminaires or lampholder outlets in a wall shall be marked on the interior of the box to indicate the maximum weight of the luminaire that is permitted to be supported by the box in the wall, if other than 23 kg (50 lb).
The problem is the word "other" used in this NEC section. "Other" implies that the permitted weight of the box could be less than or greater than 50 lbs. What I need to know is what is the present practice of the manufacturers? Do they mark the box if it can hold more than 50 lbs or less? I'm an engineer not an electrician. I nor the CMP expects the manufacturers to change their practices on account of any proposal that I make.
