Connect the tee at the top of the cable tray

Installing a top tee in a cable tray involves aligning the tee section, securing it with gussets or splice plates, and ensuring proper support and grounding.

Step-by-

Step Installation1. Plan and Mark the Tee Location Before installation, review the approved shop drawings to identify the exact location of the tee. Mark the path of the main tray and the branch tray using a chalk line or laser level to ensure alignment with the existing system.

2. Prepare the Tee Section If using a pre-fabricated tee, check that it matches the dimensions of the main and branch trays. For custom tees, cut the tray sections to size and add gussets to reinforce the junction.

Ensure all edges are deburred to prevent cable damage. 3. Install Supports Install support brackets or Unistrut channels at the tee location.

Standard support spacing is typically 1. 5 to 2 meters, but check manufacturer specifications. Ensure the supports are level and securely anchored to the wall, ceiling, or floor.

4. Position the Tee Lift the tee section into place, aligning the main tray and branch tray with the marked path. Use scaffolding or lifting equipment if necessary for safety and stability.

Ensure the tee is level and properly oriented. 5. Secure the Tee with Gussets or Splice Plates Attach gussets or splice plates at the junction points to reinforce the connection.

Tighten bolts or screws evenly to prevent misalignment. Gussets help distribute the load and maintain structural integrity. 6.

Grounding and Bonding Connect grounding straps between the tee and the main tray to maintain electrical continuity. This is essential for safety and compliance with electrical codes. 7.

Final Checks Verify that the tee is level, properly supported, and aligned with the rest of the cable tray system. Check for any interference with other services such as HVAC ducts or pipes. Ensure all fasteners are tight and that the installation meets code requirements.

By following these steps, the top tee will be securely installed, providing a stable junction for branching cable runs while maintaining safety and compliance with electrical standards.
