It would be likely that the Gypsum Wallboard Associaton or whoever has already determined what the allowed support is.
For example when you purchase a toggle bolt, it states what the allowed load is.

Without NEC giving a definition just what would you care to use ?

Gee I don't know????

Maybe the UL classification. :wink: :p

I can't be bothered looking it up but I bet Sheetrock is not classified as a framing member. :p

Is grid wire a framing member ?Seen plenty of emt hung from them with batwings

Not the same thing at all, 338.30(B) does not apply in the least to ceiling tie wire. For that you need to comply with 338.30(A).

Jim sheet rock is only a framing member on Pluto and maybe a few developing nations not in the USA. :lol:

Yes Jim, of course I do.

There is no NEC rule prohibiting me from toggle bolting a one hole clip to a sheet rock wall in order to secure an EMT.

That is not the same to the NEC as simply boring a hole through drywall and letting that support the EMT.

We may not like it or aggree with it but that IMO is the fact jack. :wink:

Plain and simple 338.30(B) does not apply at all to Sheetrock, it only applies to EMT running horizontal through framing members....thats it, not Sheetrock not ceiling tie wire, not toggle bolts.

If it's not EMT running horizontal through framing members than you must use the rule contained in 338.30(A).

By the way Don R just recently posted a link from the people that make Sheetrock and they say it is not to used to support fixtures from the ceiling at all which was news to me. :shock:

Kind of throws a wrench in Old work High hats. :p

Bob think about what you just said.A strap held by drywall and toggle bolt is ok but emt without the strap is not ok.Sorry Bob but that is flat out crazy.
The drywall disclaimer is equal to klines disclaimer on insulation on your kline blue handles.They just protecting there -----.we all know why we paid $30 plus bucks for them.

I know exactly what I said and I stand by it. 8)

supported is a different concept in the NEC than secured

If you feel it is crazy put in a proposal to change it. 8)

Jim if the listing on the drywall product does not allow it to used as an overhead support it will probably be a building code violation to use it as such.

No different than using a suspended ceiling grid as support when it is not listed for that use.

The OP was asking about support.So your saying i can secure it to drywall but not support it ????

What I am saying is that code section 358.30(B) that allows horizontal runs of EMT to be supported by openings through framing members does not in anyway allow an opening (hole) made in Sheetrock to support EMT.

That being the case we have to use 358.30(A) which requires EMT to be secured. Once we know we must secure the EMT we can look at 300.11 to see what secured means.

300.11 Securing and Supporting.
(A) Secured in Place. Raceways, cable assemblies, boxes, cabinets, and fittings shall be securely fastened in place.....

IMO a toggle bolt holding a Minni or 1 hole clip to a Sheetrock wall is secured. But as always that is for the inspector to decide.

Secured is stronger than supported ?

Yes.

Open your hand palm side up.

Drop a quarter in your palm.

You are now supporting the quarter. :)

Now I am coming along to take that quarter so you close your fingers around the quarter.

The quarter is now secured. 8)

Or based on your listed interests exchange the quarter for a cheeseburger. :wink:

So if i have this right,drywall can be used to secure what it cant support.
Click to expand...

I think you got it. 8)

It does not have to make sense....it only has to be compliant.

Like I said earlier if you really feel it's that crazy you can submit a proposal.

But before you do go back and read sandsnows post and see if this really needs 'fixing' in my experience inspectors do exercise common sense and sometime do not 'see' everything. :wink:
 
And they wonder why electricians drink :lol: You got to admit this sounds crazy and now we still have the issue of if drywall can be used to secure anything.Having done it for 20 plus years does not make it right but does prove it works.
