Cable tray elbow fabrication quota numbers are specific identifiers used by manufacturers to standardize ordering and fabrication, and they are typically obtained from technical catalogs or CAD libraries provided by the manufacturer.

Understanding Fabrication Quota Numbers

A fabrication quota number for a cable tray elbow is essentially a part number or specification code that defines the type, size, material, and angle of the elbow fitting. These numbers are used to:

• Ensure correct fabrication according to project requirements
• Facilitate ordering and inventory management
• Maintain compliance with standards such as BS EN 61537, NEMA VE 1-2017, or UL certifications Elbows are available in various configurations, including 90° and 45° bends, horizontal or vertical transitions, and custom angles, and the quota number will reflect these characteristics.

How to Obtain the Quota Number

1. Manufacturer Catalogs and Technical Guides: Companies like Eaton, ABB, Legrand, and SFSP provide detailed catalogs and technical guides listing all cable tray accessories, including elbows, with their corresponding part numbers .
2. CAD Libraries and BIM Objects: Many manufacturers offer CAD drawings and BIM objects for elbows, which include the fabrication or part number. These can be downloaded and referenced in project documentation .
3. Direct Technical Support: If the quota number is not listed in catalogs, you can contact the manufacturer's technical support to request the correct part number for your specific cable tray type, size, and material .
4. Project Specifications: Engineering or procurement documents often specify the required elbow type and size, which can then be matched to the manufacturer's quota number for ordering and fabrication.

Key Considerations

• Material: Steel (pre-galvanized, hot-dip galvanized, stainless), aluminum, or FRP
• Tray Type: Ladder, perforated, or solid-bottom
• Load Rating: Ensure the elbow supports the required cable load
• Standards Compliance: Verify compliance with local and international standards (BS, NEMA, UL, ISO) By following these steps, you can accurately determine the fabrication quota number for any cable tray elbow required in your project. This ensures proper installation, compatibility, and adherence to safety and quality standards.
