Neutral terminal block in gutter?

[JerryM]

Had a debate a couple of weeks ago with an inspector who wanted me to install a "neutral terminal block" in my NEMA3R aluminum gutter to land all of the ungrounded conductors. I told him I'd never seen such a thing. He was referring to the 2014 National Electrical Code Handbook and said there was a drawing showing this block, so he wanted me to put one in. After a lengthy discussing, he backed off and agreed to the standard bonding of the gutter.
Yesterday, he ran into my estimator and gave him a copy of the page from his book, page 177. I confess I'm not up to date on much of 2014NEC yet (more on the resi side) so if this is something that is new, could someone point me to it in the Code?

There's a couple problems with the inspector trying to use the handbook instead of the actual code book.



First of all, the pictures and commentary in the NECH are not code, they are simply opinions of the authors.

From the first page of the handbook

The commentary and supplementary materials in this
handbook are not a part of the NFPA Document and do not
constitute Formal Interpretations of the NFPA (which can be
obtained only through requests processed by the responsible
technical committees in accordance with the published
procedures of the NFPA). The commentary and supplementary
materials, therefore, solely reflect the personal opinions of the
editor or other contributors and do not necessarily represent the
official position of the NFPA or its technical committees.

Second, the picture he is referring to is "EXHIBIT 250.11 An example (note the word example) of the bonding requirements for service equipment" it is not a requiremnt, it's just one way to do it, you can choose other ways that achieve the same end product.

BTW, you meant to say "land all of the grounded conductors.
