Burrito Q: Fastening of EMT

[Jim W in Tampa]

A includes B (IMO). In other words, when you strap, you support.

If you support, you do not necessarily strap.

If you always have to do A, what is the purpose of B?

I was never very good in sentence structure but I think 358.30 could be a bit better worded.

Doing A does necessarily mean you have done B
I could strap conduit on a wall but depending on its size and whats in it ,the strap might not support the weight.

I bet some by now would change there vote if they could.

I would propose you have not performed A if the strap will not support the weight.

I agree its unlikely but i have ran plenty of 4 inch that i was counting on the truss to hold the weight. My tie wire keeps it from moving but would never hold the weight after copper is in it. My view is we must do both A and B
Will agree it is poorly written but that is normal for nec.
If it was clear we would have had a 90% vote one way or the other.
Thankfully i will soon be totally retired from electrical. I do enjoy the field but have seen it only getting harder as years go by.

I agree with cowboyjwc. I do not consider laying on top of anything without straps as being secure. Definitely not a good practice.

Some here want to believe supporting and secured are one and the same and that simply is not true. They can twist,turn and miss use NEC all they care to. NEC made it clear they are not one and the same, that is why they have A and B. I wish George would run a new pole as i believe the revote will show a serious change. This time no bribe with a birrito.

Jim, I don't believe the opposition feels that way at all. I believe they are well aware of the difference, and feel that B gives permission to leave a conduit unsecured under certain conditions.

Since that is apparently the intent of B, then it is a valid viewpoint. That is the way "it's supposed to be."

I do not believe that the poll would change one iota. One thing that the poll has made dramatically clear, is that there is no middle ground on the issue to speak of. There are two sides to this issue, and each side is firmly convinced that they are correct. Last I checked, only one respondent felt the code was unclear - everybody else thinks the code clearly supports their belief.

As you wish, i just hate seeing so many reading it wrong. If they are right I have wasted many many hours on strapping. I have seen plenty of conduit that went slightly over the 10 foot rule but never seen any with no securing. How do we get Mike to give his answer ?

So at least we know why you're so adamant about this.

Thats odd because during this thread you lead us to believe you would never leave it unsecured code or no code. :grin:

I posted a quote from Mike, he says Roger and I are right.:grin:

See the bottom of post 60.

And i still won't, i was simply pointing out stupid the idea is.

Bob, your back to your old ways of twisting words. Mikes answer was to another question about METAL STUDS.

See the bottom of post 60.

Q 3. When EMT is installed within metal studs and it is not resting on the bottom of the opening, is additional support required?

A 3. Horizontal runs of EMT is considered supported by openings through framing members where securely fastened within 3 ft of termination points [358.30(B)]. The key word here is "supported". If the raceway is not resting on the framing member, then it is not supported. This does not mean that the conduit must rest on every framing member. As long as it is resting on one framing member every 10' and it is securely fastened within 3' of the tubing termination points, the installation complies with the NEC.

Care to show us his answer for ROOF TRUSSES ?? An answer to one question can't simply apply to any question.

Jim, the question is regarding framing members, roof trusses are framing members.

Jim, please don't be a nit wit.

The question Mike Holt answered is about code section 358.30(B) and that code section is about framing members not 'metal studs'.

358.30(B) Supports. Horizontal runs of EMT supported by openings
through framing members at intervals not greater than
3 m (10 ft) and securely fastened within 900 mm (3 ft) of
termination points shall be permitted.

Jim, you need to go back and read the first post.

Permitted to do what ? SUPPORT
358.30 (b) is about SUPPORTS not (a) securing
My vote stays as i am sure yours will too.
Try and get a job like that passed by an inspector. Good luck.
