Cable tray connecting tee

A cable tray tee is connected using a combination of tee fittings, splice plates, and bolts, or by on-site fabrication with brackets, ensuring a secure, stable, and code-compliant junction.Steps to Connect a Cable Tray Tee

1. Select the Appropriate Tee Fitting Use a tee-shaped plate or fitting designed for your cable tray system. This fitting has three connectors to join the main tray and the branch tray at a junction, allowing cables to split safely and maintain system stability . 2. Prepare the Tray Sections

• Align the main tray and the branch tray at the desired junction.
• If necessary, cut or notch the main tray to accommodate the branch tray, ensuring the edges do not interfere with cable placement .
• Ensure the tray ends are clean and free of burrs to prevent cable damage. 3. Attach the Tee Fitting
• Place the tee fitting at the junction where the three tray sections meet.
• Use splice plates or L/T/cross plates to secure the fitting to each tray section. These plates are typically flat metal with pre-drilled holes .
• Align the holes of the tray and fitting carefully to ensure a tight connection. 4. Fasten with Bolts and Nuts
• Use the recommended bolts, nuts, and washers to secure the splice plates and tee fitting.
• Tighten bolts with a spanner or torque wrench to ensure a strong, vibration-resistant connection .
• For some systems, quick-connect brackets or specialized TX brackets can be used to fabricate tees on-site, bending the tray sidewalls and securing with bolts . 5. Check Alignment and Stability
• Ensure the tee junction is level and properly aligned with the rest of the tray system.
• Verify that the connection can support the expected cable load without sagging.
• Install riser links or hold-down units in pairs if required for additional support . 6. Final Inspection
• Confirm that all bolts are tightened and the tray edges are smooth.
• Ensure the tee connection complies with local electrical codes and manufacturer guidelines .
• Test for stability by gently applying pressure to the junction to check for movement.

Tips and Considerations

• On-site fabrication: Some systems allow you to create a tee by cutting and bending tray sections, which can save time but requires careful alignment .
• Material compatibility: Ensure the tee fitting and fasteners match the tray material (e.g., steel, aluminum, or stainless steel) to prevent corrosion .
• Future maintenance: Use connections that can be undone if trays need to be reconfigured or extended . By following these steps, you can create a secure, durable, and professional cable tray tee connection that supports cables safely and meets installation standards.
