I actually think inspectors are easing up on enforcing this particular code grey area, but nonetheless we haven’t run NM directly into Soladecks. I imagine that using a regular NM cable clamp connector would work.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">When we do run NM, we terminate it in indoors in a permanently accessible box typically located in the attic or on the ceiling or wall by the roof penetration location. Then, we run EMT through the roof and to our rooftop J-box. THWN-2 is run between these two boxes. Then, the microinverter (or ACPV) wire is spliced to the THWN-2 at the rooftop J-box. Yes, this means three wire types for each install! We’re using splice cap crimp connectors for all of our splices which we’re very happy with: <a href="http://www.idealindustries.ca/products/wire_termination/terminals_crimps/crimp_connector_splice_cap.php">http://www.idealindustries.ca/products/wire_termination/terminals_crimps/crimp_connector_splice_cap.php</a> - ferrules are available for fine stranded conductors.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">August</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d"> </span></p><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> 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>Jason Szumlanski<br><b>Sent:</b> Tuesday, July 26, 2016 9:08 AM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] New Construction Enphase Romex / NM</span></p></div><p class="MsoNormal"> </p><div><div><p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">It seems like most jurisdictions are now allowing a transition to Romex in a Soladeck box where the Romex enters the attic immediately and runs in protected space all the way back to a load-side interconnection or combiner panel.

Even though it's a short distance from the j-box to the point where the conduit penetrates the roof plane, it's still a wet location so Romex isn't allowed. In fact, some jurisdictions are requiring this even for Soladeck boxes because they consider the Soladeck an enclosure in a wet location so the inside must also be considered a wet location, making the transition to Romex improper in their opinion.</span></li></ul><div><p class="MsoNormal"><span style="font-family:"Arial","sans-serif""> </span></p></div><div><p class="MsoNormal"><span style="font-family:"Arial","sans-serif""> </span></p></div><div><p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">Jason Szumlanski</span></p></div><div><p class="MsoNormal"><span style="font-family:"Arial","sans-serif"">Florida Solar Design Group</span></p></div><div><p class="MsoNormal"><span style="font-family:"Arial","sans-serif""> </span></p></div></div><div><div><div><div><div><div><div><div><div><div><div><div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal"> </p></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></body></html>
