Photovoltaic cable tray construction requirements
Historically, the NEC has allowed cable trays, but has lacked specific guidelines for sizing conductors and using smaller conductors like PV wire and DG cable on rooftops. In this installment of our Code Corner series, Ryan Mayfield focuses on the 2023 National Electrical Code (NEC) changes concerning cable trays, particularly section 690. 2 standard provides the technical require-ments for the construction le tray s methods to meet. Use of standard grades of plastic wire ties is by far the most common method used by installers to support and secure direct current (DC) string wiring in an array. The implications of failed. Section 690. 31 is pretty clear: PV source and output circuits need to be supported by non-combustible hardware. No more letting cables drape across roof tiles or ride over sharp flashing. And don't forget—AC and DC conductors need to stay separate, or you're asking for interference and heat issues. A rung spacing of 6 to 9 inches (150 to 230 mm) is preferable when.
