In the 2011 code is it really necessary to strap a 1/2 inch x 1 inch long EMT nipple between panels? I am going blind trying to find the exception but it appears this is the new code requirement.
What code section is that one?
In a code change book I have what they are talking about is.
For the 2011 the section that had the 18'' rule has been deleted, the support requirements go back to the 36'' from enclosure. So if there is less than 36'' between enclosures there is no need for a strap.
The current code wording, and the wording in codes prior to 2008, require a strap no matter how short the nipple is. The rule in the 2008 code was an attempt to make the code match the real world installation practices. The current wording does not imply that a support is not needed if the nipple is less than 36". It only says that you must support withing 36" of the conduit termination. There is nothing in the raceway articles to suggest that the conduit termination itself can be used as a support. The CMP should have accepted the original proposal for the 2008 code which would have eliminated the requirement for a support where the conduit was less than 36" long.
I don't even think there is any interpretation required...the wording clearly requires a support no matter how long the raceway is....True as it was worded, and is again, one could interpret a close nipple between two enclosures as requiring an additional support besides the termination points.

Too late for a 2014 proposal.
"Exception: Unbroken lengths of raceway, install between two fixed enclosures, measuring 36" or less, shall be permitted to be supported by their conduit terminations."

The code requires the strap...I don't think the CMP really understands the issue that needs to be addressed.So do/would you require a strap on a close nipple? It fits the description of what needs secured.
I don't see a need to prohibit bends.How about this,
"Exception: Unbroken lengths of raceway, without any bends, installed between two fixed enclosures, measuring 36" or less, shall be permitted to be supported by their conduit terminations."
