The point was made (on this listserve) that "<i>if the inside of a 3R enclosure isn't considered dry enough for a <span class="gmail-il"><span class="gmail-il">buchanan</span></span> <span class="gmail-il"><span class="gmail-il">crimp</span></span>/cap, then there's millions of 3R panels with breakers and busbars in them that would have the same problem</i>". The inspection agency finally relented. We put a little No-Alox in the cap. I know that's not what your initial post was about, but tossing that in for consideration just in case...</font></div><div><font size="2"><br></font></div><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div>Adam Katzman (he/him)<br>Autonomous Energies | Owner/Operator</div><div dir="ltr"><a href="http://www.autonomousenergies.com" target="_blank">www.AutonomousEnergies.com</a><br>(518) 567-1468<br></div></div><div dir="ltr"><br><br></div></div></div></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Nov 11, 2025 at 3:51 PM Jay via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank">re-wrenches@lists.re-wrenches.org</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"><div dir="auto"><div dir="ltr"></div><div dir="ltr">Hi Sam</div><div dir="ltr"><br></div><div dir="ltr">I can’t imagine being just copper it would matter, the AHJ might have a different opinion however </div><div dir="ltr"><br></div><div dir="ltr">Question. </div><div dir="ltr">How are you insulating them?</div><div dir="ltr"><br></div><div dir="ltr">Jay</div><div dir="ltr"><br></div><div dir="ltr"><br><blockquote type="cite">On Nov 11, 2025, at 11:15 AM, Sam Haraldson via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank">re-wrenches@lists.re-wrenches.org</a>> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr"><div dir="ltr">Wrenches,<br><br>On the attached product spec sheet for Ideal Copper Crimps (aka Buchanan crimps) you'll see that max voltage for the crimp is rated at 600V but an asterisk indicates up to 1000V when "in fixtures and signs". In our application this is a 1000v system and we are joining pairs of #10 PV wires. The junctions are made in a rail-mounted, plastic j-box. We could not find the definition of "fixture" as it might pertain to this situation in the NEC and as such are interested to learn more about using Buchanan crimps for 1000V applications.<div><div><br></div><div><div><image.png></div><br></div><div><br></div><div>Cheers,</div><div>Sam<br> <div><div dir="ltr" class="gmail_signature"><div dir="ltr"><table cellpadding="0" cellspacing="0" style="font-family:Carlito,Tahoma,sans-serif"><tbody><tr><td style="padding:0px 10px 0px 0px;vertical-align:top"><a href="https://onsiteenergyinc.com/" style="border:medium" target="_blank"><img src="https://cdn.prod.website-files.com/675cb4f269e8da457106c938/67acde8cf274634235411bdd_email-sig-logo-onsite-energy.png" alt="OnSite Energy" align="top" width="95" height="95" style="display: block;"></a></td><td style="padding:0px;vertical-align:top"><table cellpadding="0" cellspacing="0"><tbody><tr><td style="padding:0px 10px 0px 0px;vertical-align:bottom"><div color="#514ca0" style="padding:0px;color:rgb(81,76,160);font-size:14pt;font-weight:600;text-transform:uppercase">Sam Haraldson</div><div color="#f9a145" style="padding:0px;color:rgb(249,161,69);font-size:11pt">Operations Specialist</div><div color="#514ca0" style="padding:0px;color:rgb(81,76,160);font-size:8pt">(406) 551-6135</div><div color="#514ca0" style="padding:0px;color:rgb(81,76,160);font-size:8pt">1515 N.
