11090-degree cable tray installation

Installing a 110-degree cable tray involves careful planning, precise alignment, and proper support to ensure safe and efficient cable routing.

Planning and Preparation

Before installation, plan the tray route according to your electrical layout, considering clearance, load capacity, and cable separation requirements. Ensure the design complies with local electrical codes and safety standards, such as the Canadian Electrical Code (CEC) or applicable national regulations (Unitray Installation Guide). Identify where the 110-degree bend will be placed and verify that the tray type and size can accommodate the bend without exceeding the minimum bend radius for the cables.

Selecting the Right Components

Use compatible fittings and connectors designed for your cable tray system. For a 110-degree bend, you may need a custom or adjustable angled fitting, or you can fabricate the bend on-site if the tray material allows (Legrand Installation Guide). Ensure that all hardware, including brackets, clamps, and fasteners, is rated for the tray load and environmental conditions.

Support and Mounting

Secure the tray using appropriate supports such as wall brackets, ceiling hangers, or strut systems. Maintain proper support spacing, typically 1. 5 to 3 meters apart, depending on tray type and load (Elcon Global Guide).

For center-hung trays, ensure the maximum load per hanger is not exceeded, usually around 318–340 kg (700–750 lbs). Supports should be aligned to prevent sagging, especially at the bend. Installing the 110-Degree BendAlign the tray sections leading into and out of the bend to ensure smooth cable transition.

Attach the bend fitting securely using the recommended connectors or bolts. Ensure the bend maintains the correct angle and does not distort the tray. Check the minimum bend radius for the cables to prevent damage or excessive stress.

For ladder-type trays, rungs should remain evenly spaced (150–230 mm) to support cables properly. Level and secure the tray sections on either side of the bend to maintain structural integrity and proper cable routing.

Final Checks

Verify that all tray sections are level, aligned, and securely fastened. Ensure cables can be installed without sharp bends or compression at the 110-degree angle. Confirm compliance with load ratings, spacing, and safety codes.

Inspect for any potential interference with other trades or equipment. By following these steps, a 110-degree cable tray can be installed safely and efficiently, providing a reliable pathway for electrical cables while maintaining compliance with industry standards and minimizing the risk of damage or hazards.
