It should be passed but being straight forward will probably be your downfall. The junk that gets adopted without any substantiation is mind boggling yet common sense proposals or ones that clarify current poorly worded section of code seem to get rejected.
CMP-8 didn't even agree with the submitter's Public Input but they voted to remove it this is the first cycle I am using the Jedi mind trick in my public inputs to gain clarity on some borderline language.
I am working in tandem with some other folks and we will make some great strides this cycle to improve the interpretations for the AHJ
I still don't feel a 24" section of 4" RMC between enclosures would require any additional support.
Even 24 inches of 1/2 inch rmc I feel should be ok.
The NEC allows 36" of unsupported raceway when entering/leaving a box so 36" should be the magic number for unsupported nipples.
How can you comply with the language must be securely fastened "within 36"?
They include specific wording that say up to 36" sections of raceway between two enclosures, boxes, etc. do not require support.
I think 36" is fine for any type and size of non-flexible raceway, other than PVC.
I agree. Broken, unbroken it should not matter. The fact that the 18" rule lasted one code cycle shows how out of touch the CMP actually is. Requiring this nipple to have a support is ridiculous.
Yet that was the only code cycle that did not require the support. Part of the issue is that the existing rule is almost never enforced so too many believe that the 18" rule was requiring a support that was never required before or after the 2008 code.
This might be something then that needs either more attention or AHJs need an amendment for clarification or best option is everyone who matters and has read this thread should keep their mouths shut when training the next inspectors about this being a rule and then the status quo that you mentioned will be maintained longer.
I remember discussing that sort of thing one time in a CEU class, back when they first started playing with this rule in NEC. Question came up (facing reality type of question) of whether a strap on a ~3 foot length of RMC is supporting the raceway or whether the raceway is supporting the strap.
I didn't read through all posts before my previous one
PVC also requires first support to be within 36", so I feel it is fine with no additional supports as well for 36" and less runs.
No problem. I usually respond with short, succinct replies, so my answers are often missed and repeated.I didn't read through all posts before my previous one
Imagine bending an offset in a 4 foot long nipple of 4" RMC just so you can put that strap on it.
