On an array of two strings of Mitsubishi 175s (Isc = 7.9A) I had two 15-A breakers open. Last week, I had a low-power call from a customer with three strings of Evergreen 190s (Isc = 7.1A); one 15-A breaker in the combiner was open. Most of my installs are around 3000 ft elevation, so the irradiance is possibly a little higher than normal, but not by enough that it should be an issue for 15-amp breakers. If this is a wide-spread problem, I'd expect others on this list to have noticed.<br><br>As others have mentioned, it is important to take precautions to make sure that stranded wires are well tightened in these breakers. I tighten, wiggle, re-tighten, and then check again later. On systems where I've had breakers open, loose connections haven't been the issue.<br><br>Kent Osterberg<br><st1:place w:st="on"><st1:placename w:st="on">Blue</st1:placename><span class="Apple-converted-space"> </span><st1:placetype w:st="on">Mountain</st1:placetype></st1:place><span class="Apple-converted-space"> </span>Solar, Inc.<br><a href="http://www.bluemoutainsolar.com/" style="color: blue; text-decoration: underline; ">www.bluemoutainsolar.com</a><br><br><o:p></o:p></span></font></div><pre wrap="" style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 10pt; font-family: 'Courier New'; color: black; "><font size="2" color="black" face="Courier New"><span style="font-size: 10pt; ">Can you be more specific as to what<o:p></o:p></span></font></pre><pre style="margin-top: 0in; margin-right: 0in; margin-bottom: 0.0001pt; margin-left: 0in; font-size: 10pt; font-family: 'Courier New'; color: black; "><font size="2" color="black" face="Courier New"><span style="font-size: 10pt; ">problems you have had? <o:p></o:p></span></font></pre></div>_______________________________________________<br>List sponsored by Home Power magazine<br><br>List Address:<span class="Apple-converted-space"> </span><a href="mailto:RE-wrenches@lists.re-wrenches.org" style="color: blue; text-decoration: underline; ">RE-wrenches@lists.re-wrenches.org</a><br><br>Options & settings:<br><a href="http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org" style="color: blue; text-decoration: underline; ">http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org</a><br><br>List-Archive:<span class="Apple-converted-space"> </span><a href="http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org" style="color: blue; text-decoration: underline; ">http://lists.re-wrenches.org/pipermail/re-wrenches-re-wrenches.org</a><br><br>List rules & etiquette:<br><a href="http://www.re-wrenches.org/etiquette.htm" style="color: blue; text-decoration: underline; ">www.re-wrenches.org/etiquette.htm</a><br><br>Check out participant bios:<br><a href="http://www.members.re-wrenches.org" style="color: blue; text-decoration: underline; ">www.members.re-wrenches.org</a><br><br></o:smarttagtype></o:smarttagtype></o:smarttagtype></o:smarttagtype></o:smarttagtype></o:smarttagtype></o:smarttagtype></div></span></blockquote></div><br></div></body></html>
