What does a new label mean for PV equipment?
A new label was added to identify PV equipment floating on – or attached to structures floating on – bodies of water. Per the code revision, this equipment must be identified as being suitable for the purpose and shall utilize wiring methods that allow for any expected movement of the equipment. white paper edition
Why did NFPA remove color requirements?
The marking language requirements in the Fire Code, NFPA 1 11.12.2.1.1.2, and the NEC were different, making it unnecessarily difficult for enforcement and inspections agencies to align. Removing specific color requirements now allows local enforcement agencies more latitude.
Should you check local codes before defining labeling formats?
Always check local codes before defining labeling formats. Todd Fries is a product category manager of identification systems with HellermannTyton North America in Milwaukee, Wisconsin. He also serves on Code-Making Panel 4 of the NEC 2023 and is involved with the changes and additions discussed in this article.
How do I identify a PV system DC circuit conductor?
(2) Identification: PV system dc circuit conductors shall be identified at all termination, connection, and splice points by color coding, marking tape, tagging, or other approved means in accordance with 690.31(B)(2)(a) and (b). Exception: Where the identification of the conductors is evident by spacing or arrangement, further
