How to connect an 80mm cable tray

Connect an 80mm cable tray using splice plates, bolts, and clamps to ensure a secure, level, and grounded installation.

Step 1: Plan and Prepare

Before connecting the trays, plan the route and ensure the 80mm tray sections are aligned with your electrical layout, considering clearance, load, and cable separation requirements . Inspect all tray sections and accessories for damage and verify that you have the correct splice plates, bolts, nuts, and grounding clamps .

Step 2: Align the Tray Sections

Place the two tray sections end-to-end on their supports. Ensure they are level and properly aligned to prevent sagging or misalignment. Use a spirit level and measuring tape to confirm straightness .

Step 3: Attach Splice Plates
  • Use flat metal splice plates with pre-drilled holes to join the tray ends.
  • Position the splice plate so that it overlaps both tray ends evenly.
  • Insert bolts through the holes and secure with nuts. Tighten using a spanner or torque wrench to ensure a firm connection .
  • For angled connections (L, T, or cross), use angle-specific plates designed for junctions.
Step 4: Secure with Clamps or Quick Connects
  • Depending on the tray type, you may also use clamps or quick-connect systems to reinforce the joint. These provide additional stability and can simplify future maintenance .
  • Ensure all fasteners are tightened and the tray is rigid under expected cable load.
Step 5: Grounding
  • Connect the tray to the grounding system using grounding clamps or conductors as per NEC Article 392. This prevents static buildup and ensures electrical safety .
Step 6: Final Checks
  • Verify that the tray is level, stable, and properly supported. Supports should typically be spaced 1.5–3 meters apart depending on load .
  • Check that all bolts and clamps are secure and that the tray can safely carry the intended cable weight.
  • Ensure cables can be laid without kinks or excessive bending.

By following these steps, your 80mm cable tray will be securely connected, grounded, and ready for cable installation, providing a safe and durable cable management system .
