<div dir="ltr">The process is very regimented. Here's a link with the details: <a href="https://www.nfpa.org/Codes-and-Standards/Standards-Development/How-the-process-works">https://www.nfpa.org/Codes-and-Standards/Standards-Development/How-the-process-works</a><div><br></div><div>A few things to note:</div><div><br></div><div>All submitted public inputs (PIs) are addressed by the relevant Code Making Panel (CMP); the NFPA has transitioned so that all this documentation is online (there used to be a PDF) - it can be viewed on the "Next Edition" tab of NFPA 70 here: <a href="https://www.nfpa.org/codes-and-standards/all-codes-and-standards/list-of-codes-and-standards/detail?code=70&tab=nextedition">https://www.nfpa.org/codes-and-standards/all-codes-and-standards/list-of-codes-and-standards/detail?code=70&tab=nextedition</a></div><div><br></div><div>The first draft of 2023, based on all the PIs submitted, came out on 6/28/21; comments on that document were due about 12 days ago, and the second draft meeting is scheduled for late October. The product of that meeting, which will post in March 2022, will be, for the most part, the 2023 NEC.</div><div><br></div><div>Sooo, it is going to be tough to "repeal" or get rid of RS based on the current state of things. There is the NITMAM process (ugh, so many acronyms), which you can read about here <a href="https://www.nfpa.org/techsession">https://www.nfpa.org/techsession</a> and which I'm not very familiar with.</div><div><br></div><div>Please keep in mind that CMP-4 (which I am a voting-alternate on, and which has jurisdiction over 690, 705, 710, and a few other Articles) is composed of a wide range of folks, from the enforcement (AHJ) community, the IBEW, various manufacturing trade organizations, utility organizations, the fire fighting/first responder community, and solar-specific organizations. Folks have widely varying degrees of interest in \u2013 and experience with \u2013 PV, but they all bring technical expertise from across the electrical industry. You may be surprised to hear it, but requirements in regards to RS could have been a lot more stringent, a lot more quickly, without key representation from the panel members that are most dedicated to the solar industry. Furthermore this is a consensus process, and is often the case rarely does anyone get exactly what they want.</div><div><br></div><div>Many of these same folks have been very active participants in the PV Industry Forum, sponsored by SEIA, and comprised of something like 60-80 industry stakeholders that work together to craft and submit consensus Public Inputs for the first draft. In this latest cycle we submitted dozens of PIs, and the vast majority of them were accepted and became part of the first draft. This process is key to jump-starting the new Code cycle - without a Public Input to address, the code-making panel cannot "touch" a section of the code. And of course there are plenty of PIs from individuals and other organizations that are addressed by the panel.</div><div><br></div><div>Cheers,</div><div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><br></div><div>Brian Mehalic <br>NABCEP Certified Solar PV Installation Professional\u2122 R031508-59</div><div>National Electrical Code® CMP-4 Member</div><div>(520) 204-6639<br><div><br></div><div><div><div>Solar Energy International<br><a href="http://www.solarenergy.org" target="_blank">http://www.solarenergy.org</a></div></div></div></div><div><br></div><div>SEI Professional Services</div><div><a href="http://www.seisolarpros.com" target="_blank"><span style="font-size:12.8px">http://www.s</span>eisolarpros.com</a><br></div><div><br></div></div></div></div></div></div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Aug 29, 2021 at 5:28 AM Christopher Warfel <<a href="mailto:cwarfel@entech-engineering.com">cwarfel@entech-engineering.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<p>Brian, I think you serve on a CMP. (if not, anyone with
knowledge on the process would be helpful.) What is the process
for receiving and acknowledging input from non CMP members? Every
time I submitted comment, I received no response (as far as I can
remember). Thank you, Chris<br>

Movement? Maybe, but as far as I can tell it\u2019s just a forum to
complain as I see no activity that could actually impact the NEC®
via the clearly defined and delineated process. Also there are a
few flat-out false claims on the site, along with a call to action
to fix module level shutdown by\u2026having module level shutdown in
the junction box? Most of the complaints seem to come down to
connector standardization (which obviously was not the issue with
the APS meltdown that started this thread).

<p>FixMLSD has convincing arguments that MLSD is less safe
than safe than an arc fault protective device with a
standard string configuration. Given the many problems
with MLSD devices, it seems likely that this is true.</p>

<div style="overflow-wrap: break-word;">I would
once again say that; we as an industry can influence
not only the writing of the code but with what we are
<em>buying</em> OR <em>not buying.</em>
<div>If the devices we are required to install to make
things "more safe & reliable", at the cost of
our livelihoods & reputations, we all need to
make the folks that are building the RSD crap and
those who require installation of questionably safe
& reliable crap aware of these problems.</div>
<div>WE can thru either going to the code development
meetings AND NOT buying or installing this stuff.
Not too easy when a huge amount of solar is rooftop
installs. As many of the installers in the NE know
its not a single level ranch were installing this
stuff on, short season & man lift required.</div>
<div>Tell your supplier why you are not buying that
brand, let your supplier & folks on the list
what manufacture has good reliable products AND tech
support that we can understand, who we can get in a
timely fashion, and get the satisfaction of a prompt
replacement. IF we don't sell it they won't have a
job or a market.</div>

<div> </div>
<div>Did you get any kind of joy out of
APSmart on that failure? </div>
<div> </div>
<div>I will say that their tech support guy
did at least try to be helpful, but the
language barrier was really really steep
and their distribution channels are less
than ideal. Their response to a request
for compensation was that they would not
be profitable if they had to pay for truck
rolls for such a low cost item. I really
don't think they GET IT. We've been in
business for over 16yrs and this one
failure could easily have ended that run.</div>
<div> </div>
<div>I cannot imagine we're alone here. I
was told by AP that their failure rate was
0.2%. Now, I come from a reliability
engineering background in petro chemical/
big pharma where a 0.2% failure rate would
be catastrophic. Can you imagine that 2
out of every 1000 pills made could cause
death? We engineered secondary systems
and multiple quality checks to contain
catastrophic consequences for components
that had know failure rates higher than
acceptable values. A simple solution to
this fire initiation issue would be a
metal enclosure instead of plastic casing.
That still doesn't really solve the
problem of extra connections though.<br>
