Thanx to Joe and all for the comments,
With Joe’s explanation I now know 2 people who follow the NEC
changes regularly; it doesn’t seem to be too common in this circle. But my
earlier point remains, it is possible to keep up with these changes by being
part of the process.
I agree with the ongoing comments showing that each of the more
than 10k Jurisdictions adopt the NEC on their own conditions. The City of LA
has always had a long list of delta’s with the code; perhaps that was their way
of pushing for changes that they thought needed. Within each Jurisdiction
each AHJ inspector has their own short list of hot button issues to contend
with. I have smoothed over installation safety conflicts by arranging a
meeting with the AHJ inspector, preferably at the equipment/jobsite to get
agreement on what has to be done then working with the equipment supplier to
get the work in place and properly identified as being adequate and walking the
inspector thru the completed work to get agreement.
From a foreign outsiders point of view this is all confusing.
Any company getting involved in selling electrical products in the US must come
up to speed as quickly as possible in order to avoid getting stopped selling or
installing their equipment here.
Harmonization of technical requirement over the last 30+ years
has been helpful for the classes of equipment that have participated; the
understanding of the specific country requirements and certification procedures
has gotten more complicated. This has been a recurring IEEE ISPCE conference
theme.

Subject: Re: [PSES] NEC 2017
As far as I know in North Carolina the NEC is adopted by version so the 2017
version will not apply until specifically adopted. NC usually waits a few
years after the initial release for things to shake out before adopting the
latest. And I believe the local inspector in NC has authority to accept or
require what he wants regardless of the NEC.

Not only do states adopt specific versions, they often adopt just parts of
specific versions. And unless they put specific language in the adoption law to
allow newer or older sections, they are usually bound by what exactly was
adopted.

Hi Pete:
Here’s my experience with keeping track of upcoming changes in NFPA 70.
For the last two years I have been following the development of the 2017
edition of NFPA 70 because of some changes that it makes to Article 840,
“Premises Powered Broadband Equipment.” In order to see the current draft of
the 2017 edition and the committee comments, I had to join the NFPA for $175,
but it was worth it to me because the changes in Article 840 directly affected
a project I was working on.
While joining the NFPA allowed me to view the current draft on my computer
screen, there was no way to download the document or even copy anything more
than what is on the screen.
In summary, it *is* possible to see the draft version as it develops, but it
requires some effort. This may have changed recently because I believe the
final draft has been officially voted on and adopted.
On a related note, I have found that when each state or jurisdiction adopts
NPFA 70 into their local laws, the legislation often specifies a specific
edition of NFPA 70. For example, as of last year when I was looking at this,
the state of Connecticut’s law still called out the 2005 edition of NFPA 70.
This seems problematic for dealing with changes in the NEC over time.
I’m not sure what happens when a revised requirement appears in an edition of
NFPA 70 that is newer than the edition called out by the laws of the local
jurisdiction. Two types of situation can occur:
1) The new requirement is MORE restrictive than the version in the edition
called out in the legislation
2) The new requirement is LESS restrictive than the version in the edition
called out in the legislation
Does anyone in this group know how that works? My impression that the specific
individual doing the inspection (the AHJ) has wide latitude to pick and choose
from both editions, but this may be a mistaken impression. It certainly would
create a lot of uncertainly for a company that is trying to deploy a single
product throughout the USA.

Doug, et al,
If you were really interested you would be involved in the
committee that revises the NEC every 3 years and have already read the
pertinent changes in which you are interested.
All of these changes are done in an open forum and the documents
seem available; I don’t follow them, however.

Have we established that the 2017 edition actually has NRTL vs Listed?
I would like to hear some clause references since it is nearly 600 pages.

The NEC is a model standard and intended to be adopted by local and state AHJs.
In doing so, the AHJs often take exception to some requirements, and add some
requirements. In adopting the NEC, the AHJs must specify what “listing” means
– what third-party certifiers are acceptable to the local or state AHJ. The
NEC has not mentioned or specified by name a third-party certifier.
AHJs accept third-party certifications according to their local or state rules.
A specific NRTL certification may or may not be currently acceptable.
Now that the 2017 NEC specifies NRTL, it will be interesting to see how the
local and state AHJs accept specific NRTLs, or NRTLs by standards (as does
OSHA), or blanket all NRTLs. Note that AHJs have different objectives than
OSHA, who runs the NRTL program.
