New NEMA Engineering Bulletin would be a valuable adjunct to photovoltaic (PV) training
UL in conjunction with several North Central Texas inspection authorities held
a one-day training session on photovoltaic and supporting emerging
technologies, including panel discussions on electrical requirement. As more of
these training sessions are conducted around the country, UL should consider
including as a handout, the newly posted NEMA
Engineering Bulletin 103, Photovoltaic Wiring Methods.
This Bulletin offers a concise summary of
Article 690 wiring methods permitted as alternatives to the general wiring
methods in NEC® Chapters 1 through 4. The need for electrical installer
education is continual given the changes in the Code and the introduction of
new technologies. Engineering Bulletin 103 provides an effective update on
wiring options for the growing PV landscape.
