Building wire industry steps up for proper installation and use of its products
Kudos to the building wire and cable technical committee for taking action over the past several months to publish two new NEMA Engineering Bulletins that are relevant to the growing number of photovoltaic installations. Bulletins 103 and 105 educate contractors on the wiring methods that can be used in PV in addition to those in NEC Article 690, and provide guidance on proper terminating of fine-stranded wire prevalent in these installations. The industry is to be congratulated for being proactive and giving electricians and inspection authorities valuable guidance on the proper use of building wire in PV applications as the number of PV installations and PV system installers increase.
