Installing cable tray support plates

Cable tray connector plates (splice plates) are installed by aligning tray sections, securing the plates with nuts and bolts, and ensuring proper torque and grounding for a stable, safe system.

Step-by-

Step Installation1. Prepare the Tray Sections Before connecting, ensure the ends of the cable trays are clean, free of burrs, and properly aligned. Inspect for any damage that could affect stability or grounding.

2. Position the Splice Plate Place the flat metal splice plate over the ends of the two tray sections to be joined. The plate should cover both sides of the tray and align with the pre-drilled holes.

3. Insert Fasteners Use the appropriate nuts and bolts through the holes in the splice plate and tray sides. Ensure you select the correct size and type of fastener recommended by the manufacturer.

4. Tighten with Proper Torque Secure the nuts and bolts using a wrench or socket set. Proper torque is critical to prevent loosening due to vibration and to maintain long-term stability.

Avoid over-tightening, which can deform the tray or plate. 5. Check Alignment and Level Ensure the connected trays are straight, level, and properly supported.

Misalignment can cause sagging or stress on the tray system. 6. Grounding and Bonding For metal trays, install grounding jumpers across the splice plate to maintain electrical continuity.

This is essential for safety and compliance with electrical codes. 7. Inspect the Connection Verify that all bolts are tight, the splice plate is flush with the tray, and there are no gaps or misalignments.

Check that the tray can support the expected cable load without sagging.

Additional Tips

Support Spacing: Ensure supports are installed at recommended intervals (typically 1. 5–2 meters) to prevent excessive load on the splice plate. Safety Gear: Always wear gloves, safety glasses, and a hard hat during installation.

Quick Connect Options: Some systems offer snap-on or slide-in connectors for faster assembly, reducing installation time by up to 50%. Documentation: Label and document the connection for future maintenance and inspection. By following these steps, cable tray connector plates provide a secure, durable, and code-compliant connection that ensures system stability, safety, and ease of maintenance.
