NEMA BI-50016-2024 (formerly VE 2) is the most recent standard addressing shipping, handling, storing, and installing cable tray systems, including optical cable trays, and provides guidance on maintenance and system modifications . This standard ensures proper installation practices and system reliability, covering both metallic and nonmetallic cable trays used in electrical and communication systems. The document is available in electronic PDF format through the ANSI Webstore .
For nonmetallic cable trays, UL 568 is the relevant standard, reaffirmed as of November 29, 2023. It specifies requirements for nonmetallic cable trays and associated fittings in accordance with the National Electrical Code (NEC) and the Canadian Electrical Code (CEC). This revision updated the title page but did not introduce technical changes . UL 568 is particularly relevant for installations requiring compliance with NEC rules for optical and electrical cables.
The IEC 61537:2023 standard provides international guidance for cable tray and ladder systems, including optical cable support. It specifies requirements and tests for cable trays and ladders used in electrical and communication systems, and introduces technical revisions such as the use of trays as protective earth conductors . This standard is useful for projects requiring alignment with global practices.
