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" data-smartmail="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:none" 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" data-unique-identifier=""></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.
