have ac circuits lower than 8' all through my basement,

<p>As far as ground mounted arrays are concerned
there is one clear protection mandated by the
NEC-the requirement for protection from physical
damage for all conductors under 8'.. although
this isn't as specific or redundant as rapid
shutdown requirements, it typically means
conduit or at least some kind of physical
barrier with the intention often referenced as
protection for children or other unqualified
personnel. Not sure if that fits into the point
you were making but it seems worth mentioning.</p>

at UL3741 over and over. Here is what I

mandated there was a reevaluation of what
voltages were actually dangerous for
firefighters to be exposed to. It turns
out 80 VDC is not dangerous and, given all
of the circumstances for firefighters,
exposure to voltages that are much higher
is safe enough. For some reason I have
not yet grasped, all of the components

the hallowed UL3741 rating.</span></p>

there is another disconnect here (pun

not be required to protect that wiring in
any specific manner. If I were to install
a 240VAC, over-current protected and
de-energizeable air conditioning feeder
without conduit, I would be red-tagged in
a hot second. It may be that
fire-fighters in protective clothing can
withstand voltage above 80VDC, but can
children not wearing protective “turn-out”
clothing? Children mess around on roofs

is the NEC not protecting them by

<p>I read the wrenches post regularly, as
does Brian Mehalic. We have both been on
CMP-4 (responsible for Article 690) for
the past three code cycles. I believe a
few other CMP members probably read too.
The International Association of
Firefighters <span style="font-family:'arial','sans-serif';color:black">("largest and

<p>This is definitely not the first time
we have heard that certain RS devices
are on balance causing more trouble than
they are curing - though on the other
hand some manufacturers have certainly
figured out how to make safe and
effective MLPE. </p>
</div>
<div>
<p><br>
I'm a big fan of UL3741, I have been on
that UL technical committee for about 5
years, and it is the best approach I see
to expand both off-grid and
grid-interactive solutions that don't
require MLPE for RS. SMA for example is
very present and working hard at
revisions on that standard right now. At
this point I can't see us having any
luck in removing 690.12 requirements,
except perhaps to replace the inside the
array boundary voltage limit with only
option as 3741 listing). So please keep
asking manufacturers (inverter/rack) to
pay attention to UL3741 and design
products to meet the standard. </p>

<p> I'll clarify a few

think RSD has been a huge
and costly mistake. I
genuinely think RSD

</div>
<div>
<p> William, respectfully
your analogy to seat belts
is not an appropriate
comparison to Rapid
Shutdown. Seat-belts were
required in all new cars
starting in 1968 because
there was statistical
evidence supporting their
tremendous efficacy in
saving human life. Currently
seat belts save about 15,000
lives per year.</p>
</div>
<div>
<p> Contrasting to RSD: was
implemented because of the
following paranoid fairytale
scenario - “A firefighter is
on a burning solar roof in
the daytime, and wearing a
metal axe at their hip. the
poor guy/gal falls into live
solar glass, and shatters
it. The fall is so forceful
that the heavy-duty
fireman’s suit is punctured.
Electricity conducts through
the axe blade, through the
suit, contacts the skin, and
a DC circuit is completed
through their body.”</p>
</div>
<div>
<p> As far as I know, this
has never happened once
anywhere on earth. Let’s be
honest - this scenario has
an incredibly low chance of
ever happening in all the
future of humanity. So
considering that RSD has
never helped anyone yet, and
probably never will... How
many fires can be attributed
to RSD? How much property
damage has occurred because
of these fires?</p>

<p> <span style="font-family:'helveticaneue','serif';border:none 1pt;padding:0in">The
best path to safety for

a good job right now, so
we are seeing low quality
unreliable electronics on
the roof. I will stick my
neck out and admit that
installers are not always
perfect. Humans make
mistakes - sometimes in
initial construction, and
sometimes during repair

<p>RSD is the worst
thing to happen to
solar. Has anyone
considered civil
disobedience?</p>
</div>
<div>
<p> I wonder what
would happen if all
the installers
banded together and
refused, as a united
industry
‘brotherhood.’ WE
are the ones stuck
with the bullshit in
the aftermath.</p>
</div>
<div>
<p> I’m not being
snarky here , this a
genuine question to
the group: Does
anyone have <u>good</u>
experience with RSD?
i.e. you’re really
glad RSD was there,
and you genuinely
feel safer? you’re
glad and happy to
comply with this
code and you look
forward to
continuing to use
RSD for the rest of
your career?</p>

<p>it seems
silly that we
are required
to install
these extra
pieces of
equipment for
added
"safety", that
are actually a
fire hazard on
the roof.
Just to survey
again: how
many homes
have been
saved by RSD?
How many fire
fighters have
actually
actuated the
RSD system, so
that they
could hack
through the
array to vent
the roof? </p>
<p>I think it
should only be
required if
you have
covered so
much of the
roof with PV,
that the fire
dept can't
access
uncovered roof
to do their
venting. The
whole premise
of RSD is
flawed. IMHO,
its just
another effort
to block the
wider adoption
of solar. </p>
<p>When it comes
to off grid,
RSD causes
such a
decrease in
reliability to
amount to a
decrease in
safety, due to
possible loss
of
communications,
water, and
heat. Add the
fire hazard
and RSD is
really not
making our
customers'
lives better.
