Cable Tray Side Bracket Installation Method

Fiber and communications infrastructure knowledge brief Published 23 Aug 2021

Prepared for preliminary research by the ENSAA knowledge desk. Confirm optical interfaces, port or core capacity, electrical input and output, enclosure protection, thermal design and installation limits against current standards and product documentation.

Cable tray side brackets are installed to securely support trays along walls or other structures, ensuring proper load distribution and compliance with standards.

Preparation and Planning

Before installation, ensure you have a pre-determined layout plan designed by a qualified engineer or system designer, taking into account local building codes, clearances, and load requirements. Verify that the cable tray system and side brackets are compatible and manufactured according to standards such as BS EN 61537 for cable trays. Proper planning reduces installation time and ensures safety.

Mounting the Side Bracket

Positioning: Place the side bracket at the desired location along the wall or support structure. Brackets should be spaced according to the tray manufacturer's recommendations, typically every 3. 6 meters for standard loads.

Attachment: Secure the bracket using the screws or fasteners provided with the bracket. Ensure the bracket is level and firmly anchored to the wall, floor, or structural support. Tray Placement: Slide the cable tray onto the side bracket, ensuring it rests evenly and that the tray's weight is fully supported by the bracket.

Securing the Tray: Tighten all screws and fasteners to prevent movement. If the tray is part of a continuous run, connect adjacent trays using the manufacturer-supplied connectors or fittings to maintain structural integrity.

Load and Safety Considerations

Maximum Load: Each bracket has a maximum load capacity, often around 318–340 kg (700–750 lbs) per support. Spacing: Maintain proper spacing between brackets to prevent sagging and ensure the tray can support the cable weight safely.

Short-

Circuit Forces: Brackets must be capable of withstanding forces generated during short circuits or other mechanical stresses. Installation Safety: Only qualified personnel should perform installation, following electrical safety procedures and using appropriate personal protective equipment.

Additional Tips

Use center-hung supports when possible to allow easier cable installation from both sides. Avoid using the tray as a lifting point during handling; always lift with proper slings or dunnage. Inspect brackets and trays for damage before installation to prevent structural failure.

By following these steps and adhering to manufacturer guidelines and safety standards, cable tray side brackets can be installed securely, providing reliable support for electrical and communication cables.
