Wire Management Solutions for PV Solar Mounting Systems


Managing the source circuit conductors is a necessity in all PV systems.  The National Electrical Code (NEC) mandates proper PV source circuit wire management.  PV source circuits are defined in 690.2; generally these circuits are from the series strings of modules to the PV combiner box(es).  The applicable sections in the NEC regarding PV source circuit wire management include 690.31, 338.10, 334.30, 110.12.

Although PV modules generally come with loose conductor pigtails for serial interconnection, these conductors still must be supported as well as be protected from potential damage.  These PV source circuit conductors are generally have insulation classifications of  USE-2 / RHW-2 and PV Wire, and as such have to be supported at least every 4.5 feet (1.4m) and within 1 foot (30cm) of an enclosure. 

Depending on the application, clips, straps, ties, trays, and channels are typically used to support the conductors to meet the requirements of the code.  When the PV source circuit conductors are not within the area of the PV array, standard wiring methods for outdoor circuits under the conditions of use must be utilized.  This generally means that when PV source circuit wiring must leave the area of the array, a transition box is used to allow for the conductors to be run in appropriate raceways.
