How to install the new type of cable tray tee

Installing a ready-made cable tray tee involves aligning the tee with the main tray, securing it with appropriate fasteners, and ensuring proper support and grounding.

Step-by-

Step Installation1.

Plan and Prepare

Identify the location where the tee will branch from the main cable tray. Ensure the main tray and the branch path are free of obstructions and properly supported. Gather necessary tools: wrenches, screwdrivers, measuring tape, level, and any manufacturer-specified fasteners or clamps.

2.

Position the Tee

Place the ready-made tee so that its main run aligns with the existing tray. Ensure the branch section points in the correct direction for cable routing. Check that the tee is level and properly oriented to maintain smooth cable transitions.

3. Secure the Tee to the Main TrayUse the manufacturer-supplied bolts, nuts, or clamps to attach the tee to the main tray. Tighten fasteners evenly to avoid misalignment or stress on the tray.

For wire mesh or ventilated trays, ensure rungs or mesh sections are properly connected to maintain structural integrity. 4.

Support the Tee and Branch

Install additional supports or hangers as needed to maintain the maximum allowable span (typically 3–3. 6 meters for center-hung supports) and prevent sagging. Ensure the branch section is supported independently if it carries significant cable weight.

5.

Check Grounding and Bonding

Verify that the tee and main tray are properly grounded according to electrical code requirements. Use bonding jumpers if necessary to maintain electrical continuity across the tee connection. 6.

Install Cables

Lay cables into the tee and main tray, maintaining minimum bend radii to prevent damage. Use cable ties or separators if required to organize and secure cables within the tray. 7.

Inspect and Adjust

Confirm that all fasteners are tight, the tee is level, and supports are correctly spaced. Ensure there are no sharp edges or misaligned sections that could damage cables. Make any necessary adjustments before finalizing the installation.

Following these steps ensures a safe, structurally sound, and code-compliant installation of a ready-made cable tray tee, allowing for efficient cable routing and long-term reliability.
