As you tighten it, it rubs the strands in a circular motion, which will stretch, flatten, and tear the strands. It would work fine if you use ferrules, but not without them.</span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'> </span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'>Terminals that are rated for direct use with fine-stranded wire would have a clamping-type terminal, where the screw used to tighten the connection pushes down on a solid piece of metal which then clamps the wire. Even in this case, it may still not be approved for fine-stranded wire depending on its design.</span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'> </span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'>The Buchanan splices should be fine. They are basically the same as a ferrule, except that they are crimped with a crimping tool instead of the pressure from tightening a screw in a bus bar. The crimping tool is not in direct contact with the wire strands, so there is no tearing or other damage to the wire. However, the spec sheet does not specify the acceptable wire types, and I can’t seem to find anything with a Google search. It might be worth contacting Buchanan/Ideal to see if they have better info.</span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'> </span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'>Brian Teitelbaum</span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'>AEE Solar</span></p><p class="MsoNormal"><span style='color: rgb(31, 73, 125); font-family: "Calibri","sans-serif"; font-size: 11pt;'> </span></p><div><div style="border-width: 1pt medium medium; border-style: solid none none; border-color: rgb(181, 196, 223) currentColor currentColor; padding: 3pt 0in 0in; border-image: none;"><p class="MsoNormal"><b><span style='font-family: "Tahoma","sans-serif"; font-size: 10pt;'>From:</span></b><span style='font-family: "Tahoma","sans-serif"; font-size: 10pt;'> RE-wrenches [mailto:<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>Jeremy Rodriguez<br><b>Sent:</b> Wednesday, August 10, 2016 6:32 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] Pass through/transition box for Enphase</span></p></div></div><p class="MsoNormal"> </p><div><p class="MsoNormal">How about these?</p></div><div id="AppleMailSignature"><p class="MsoNormal"><a href="https://idealind.com/us/en/products/wire-termination/set-screw-connectors/set-screw-connectors/set-screw-wire-connectors.aspx">https://idealind.com/us/en/products/wire-termination/set-screw-connectors/set-screw-connectors/set-screw-wire-connectors.aspx</a><br><br>Jeremy Rodriguez </p><div><p class="MsoNormal">Solar Installation And Design Expert </p><div><p class="MsoNormal">All Solar, Inc. </p><div><p class="MsoNormal">1463 M St</p><div><p class="MsoNormal">Penrose Colorado 81240</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">Sent by Jeremy's iPhone.
