Hi Wrenches,
Enphase was manufacturing Engage Cable with fine strand (Type K) wiring. Due to the challenges with wire terminals that are being discussed, we switched our manufacturing lines to standard, 19 strand conductors. The transition to 19 strand Engage Cable occurred in late 2015, and the stock of fine strand cable should be largely flushed out of distribution channels at this time. Our manufacturing and distribution channels are set up to so that the product that comes in first goes out first, so hopefully you don't have to deal with this issue again.

It’s just that I prefer fusion to fission. And it just so happens that there’s an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes. And it’s wireless!” - William McDonough ________________________________ From: RE-wrenches <re-wrenches-boun...@lists.re-wrenches.org> on behalf of August Goers <aug...@luminalt.com> Sent: Thursday, August 11, 2016 7:03 AM To: RE-wrenches Subject: Re: [RE-wrenches] Pass through/transition box for Enphase Hopefully manufacturers will steer away from supplying fine stranded wires with their trunk cables – it’s been a joke trying to fine the proper listed reasonably priced parts to make these connections. I bet that a huge percentage of the installs out there are not meeting the listing for fine stranded conductors. That said, we use ferrules on the individual fine stranded conductors and then make the splices with the Ideal/Buchanan splice caps. This particular combo was presented in the SunPower ACPV instruction document and says it is listed for their class K conductors. I haven’t looked up the listing documents myself (at least recently) since this was presented in the manufacturer’s manual. As I posted before, the Ideal splice caps are the bomb! We love them and I’d highly recommend checking them out if you haven’t already.

It does not list it for use with anything other than standard stranded conductors. If it is not part of the listing, it is not approved for that use, regardless of historical or anecdotal use. That is what the NEC says, and what the UL listing says and the UL specification for their listing says. ________________________________ From: Brian Teitelbaum<mailto:bteitelb...@aeesolar.com> Sent: 8/10/2016 22:48 To: RE-wrenches<mailto:re-wrenches@lists.re-wrenches.org> Subject: Re: [RE-wrenches] Pass through/transition box for Enphase Jeremy, Without digging into the specs on the Ideal connectors, I doubt that they will work with fine-stranded wire. The problem with these types of connectors is that the set screw that you turn to tighten the connection is in direct contact with the wire strands. 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. 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. 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.
