Cable trays do not universally require a formal production license, but manufacturers must comply with national and international standards and obtain relevant certifications to legally produce and sell them.

Regulatory and Standards Overview

Cable trays are governed by technical standards and safety regulations rather than a single production license. Compliance ensures that trays are safe, durable, and suitable for electrical installations. Key standards include:

• NEMA VE 1 and CSA C22.2 #126.1: Specify manufacturing requirements for metal cable trays in accordance with the National Electrical Code (NEC) and Canadian Electrical Code (CEC) rules, including load/span designations and material specifications (aluminum, steel, or nonmetallic) .
• UL 568: Covers performance requirements for fiberglass cable trays, ensuring safe application in electrical systems .
• IEC 61537: International standard for both metal and nonmetallic cable trays, detailing mechanical strength, electrical continuity, and testing procedures .
• National Marks of Conformity: Certifications such as TSE, VDE, IMQ, GOST, and NEMA indicate compliance with local or widely recognized standards, often required for market approval .

Licensing and Certification

While a specific production license is not universally mandated, manufacturers typically must:

1. Obtain product certifications demonstrating compliance with applicable standards (e.g., UL, NEMA, IEC) .
2. Provide declarations of conformity or test reports to authorities or clients, confirming that trays meet mechanical, electrical, and fire safety requirements .
3. Follow local regulations: Some countries, like Dubai (DEWA) or South Africa (SANS 10142-1), require authority approval in addition to standard compliance, effectively acting as a licensing step for production or import .

Installation Considerations

Even with certified production, cable trays must be installed according to NEC Article 392 or equivalent local codes, covering clearances, grounding, fill limits, and separation of high- and low-power cables . Noncompliance can result in project rejection or safety hazards.

Key Takeaway

Manufacturers do not need a universal production license, but they must comply with recognized standards, obtain certifications, and meet local authority requirements to legally produce and sell cable trays. Ensuring proper documentation and adherence to standards is essential for market access and safe installation.
