--></style><div class="WordSection1"><p class="MsoNormal">Recently we were asked to do a combined inspection and engineering review of a 362.70 kWdc PV system using 5 Sungrow SG60KM-U inverters. We found issues like palm trees and air handling equipment shading significant parts of the arrays, electrician’s tape and palm fronds on the surface of the modules. But we also observed two significant Code violations: PV source conductors lying on the surface of the torch-down roof and lack of bushings at the connectors on the ends of 2” LFMC. The PV source conductors got secured and we saw bushings threaded onto the ends LFMC connectors.</p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Upon close inspection we discovered that the bushings had been broken at one point on their circumference, no doubt to simplify their attachment. Their were 11 PV source circuits (22 current-carrying 10 AWG PV Wire conductors.)</p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Is this a NEC Code violation? If so, what section would we cite? It seems obvious that the bushing had been “modified”, but I would like to be more specific. Or does it come under the workmanship category?</p><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Regards,</p><p class="MsoNormal"><o:p> </o:p></p><ul style="margin-top:0in" type="disc"><li class="MsoListParagraph" style="margin-left:0in;mso-list:l0 level1 lfo1">Peter Parrish</li></ul><p class="MsoNormal"><o:p> </o:p></p><p class="MsoNormal">Peter T.
