If I apply the rule of 156% (or 125% solar derate*125% continuous load derate) to an 18 Amp Isc module this will exceed the 25A that a 12 AWG wire can carry. I understand that the homeruns will need to be a larger AWG (10 ga), but do the solar module cables (from junction box to MC4) also need to be larger? Any guidance or reference material would be greatly appreciated.</p><p class="MsoNormal"> </p><p class="MsoNormal">Thx,</p><p class="MsoNormal"> </p><div><p class="MsoNormal">George McClellan | Senior Technical Sales Manager | REC Americas LLC </p><p class="MsoNormal" style="margin-right:0in;margin-bottom:4.0pt;margin-left:0in;line-height:8.0pt">330 James Way Ste 150<span lang="UK"> | </span>Pismo Beach, CA 93449<span lang="UK"> | </span>USA</p><p class="MsoNormal">Cell phone +1 805 704 3226 | Fax +1 805 357 6104 </p><p class="MsoNormal"><span style="color:navy"><a href="http://www.recgroup.com/" title="http://www.recgroup.com/">www.recgroup.com</a> </span><span style="color:black">| <a href="mailto:shannon.kent@recgroup.com">george.mcclellan@recgroup.com</a></span></p><p class="MsoNormal"> </p></div><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Times New Roman","serif""> </span></p><div class="MsoNormal" align="center" style="text-align:center"><span style="font-size:12.0pt;font-family:"Times New Roman","serif""><hr size="4" width="100%" align="center"></span></div><p class="MsoNormal"><span style="font-size:7.5pt;font-family:"Arial","sans-serif";color:gray"><br>This message is private and confidential and may be privileged.
