Standard installation diagram of cable tray side wall

A cable tray side wall is typically mounted using wall brackets, support arms, and fasteners, ensuring proper spacing, alignment, and load distribution according to standards.

Key Components and Layout

1. Wall Brackets: Side wall cable trays are supported by brackets fixed to the wall. Brackets should be rated for the tray type and load, and installed at regular intervals (commonly 1.5–2 meters apart) to prevent sagging and maintain structural integrity . 2. Support Arms: Horizontal support arms extend from the wall bracket to the tray, providing stability. These arms are usually adjustable to accommodate different tray widths and allow for leveling. 3. Fasteners and Hardware: Bolts, nuts, and washers secure the tray to the support arms. All fasteners should be corrosion-resistant, especially in outdoor or humid environments . 4. Tray Alignment and Spacing: The tray should be level and aligned with other sections. Minimum bend radius for cables must be maintained at entry and exit points. Rung spacing for ladder-type trays is typically 150–230 mm to support cables without damage . 5. Clearance and Safety: Maintain adequate clearance from walls, ceilings, and other equipment to allow cable installation and future maintenance. Ensure the tray is not used as a walkway or load-bearing surface for personnel .

Installation Diagram Overview

A standard side wall installation diagram includes:

• Wall-mounted bracket attached to the structural wall.
• Horizontal support arm extending from the bracket.
• Cable tray side wall resting on the support arm.
• Fasteners securing the tray to the arm.
• Optional cover for solid or ventilated trays.
• Spacing indicators for multiple trays or sections. For precise visual references, CAD blocks are available showing top, front, and side views of ladder trays, perforated trays, solid-bottom trays, and wire mesh trays with wall-mounted supports, elbows, tees, and reducers, which can be integrated into AutoCAD or other design software for planning and documentation .

Standards and Best Practices

• Follow BS EN 61537 for cable tray systems and BS 6946 for channel support systems .
• Ensure installation is performed by qualified personnel familiar with electrical safety and load requirements.
• Use compatible components designed and tested together to maintain system integrity and safety. This setup ensures a secure, compliant, and maintainable cable tray installation along side walls, suitable for electrical and communication systems.
