on a recent job i was asked by the inspector to provide a mounting detail on how my boxes for my lights were supported. they were all 2x4 pendants attached to surface mounted octagons with 3/4 emt between. Basically they are looking for me to give them a picture of 2-1/2" # 12's screwed though the tin ceiling, through the 3/4 ply and into a 2x12 ceiling joist. i could just draw it out but i would like it too look a little more professional than my chicken scratch any ideas would be great. Thanks in advance for the replies.
 
the inspector doesn't actually need a detail of the fixture itself. he would like a drawing of the box/washer/screw into the joist.
 
What???? :shock: :?

Why does he want a picture?? That's it?? No calcs???

There's no point to a picture without calc's. If he can't understand a verbal description as simple as that, he is in the wrong job.

Get some crayons and a napkin and draw it out for him. :twisted:

It is the inspectors job (IMO) in this case to judge the installation as sufficient or ask another inspector for assistance or if the install really weighs a lot, get a structural engineer to justify it. A picture of the install does nothing.

So two #12's per box? You have 1 1/2 + into the joist? Sounds bomber. What about the EMT? I'm more worried about that. Is that being used as the pendant? If so, I would not be OK with that. You need somthing threaded, such as IMC.

And just to keep an open mind: Perhaps there is more to the story?
 
I suggest removing one screw, washers and all, and handing it to him, with an offer to shoot a pic with it sitting in his palm.

Why?
 
It is my understanding that he wants a drawing of how i mounted my boxes and pipe to the ceiling. I also know that the engineer must approve them. Im sure its his way of being in the clear since he wasn't actually there to see me install them.
