Correct turning method for cable trays

Cable tray turning involves precise marking, cutting, and bending to create 90-degree bends, offsets, tees, and crosses while maintaining safety and code compliance.Key Principles

Planning and Code Compliance: Always follow electrical codes regarding tray fill capacity and separation of low and high voltage wires to prevent interference and insulation damage . Anticipate future wiring needs to avoid replacing trays later. Marking and Cutting: Use a pencil to mark dimensions accurately on the tray. Avoid cutting across slots and ensure all edges are deburred to prevent injury or wire damage. Hand grinders or bolt cutters can be used for cutting, with care to maintain smooth edges and protective coatings .

Bending Techniques

Tray Bending Bars: For solid steel trays, use tray bending bars to create 90-degree bends. Start from a marked center line and insert corrugations into the flanges equally on both sides to achieve the desired angle and dimension . Check dimensions and remove any burrs before installation. Wire Mesh Trays: For wire mesh cable trays, bends, tees, crosses, risers, and reducers can be made live on-site using bolt cutters. The cutting action drags a layer of zinc across the cut end, forming a protective layer, and rubber caps can be used to protect exposed ends . Offsets and Complex Turns: Use fabrication tables or guides to calculate the correct dimensions for offsets and angled turns. This ensures smooth transitions and proper alignment with other tray sections .

Safety Considerations
  • Clear the work area and ensure all tools are used correctly .
  • Wear appropriate personal protective equipment (PPE) when cutting or bending trays.
  • Avoid intermixing high and low voltage wires to prevent electromagnetic interference and potential hazards .
  • Restore the work area after completion and check all bends and cuts for accuracy and safety.
Practical Tips
  • Measure twice, cut once, and always verify angles before final assembly.
  • Use templates or jigs for repetitive bends to maintain consistency.
  • For live installations, ensure protective caps are applied to cut ends to prevent wire damage.
  • Document start and finish times for assessment or project tracking if required . By following these techniques, cable trays can be turned, bent, and installed efficiently while maintaining safety, compliance, and long-term reliability.
