Pre-

Installation Preparation

Review Approved Shop Drawings: Confirm tray layout, lengths, and locations according to the approved design. Material Inspection: Check all trays, fittings, and accessories for damage or discrepancies before installation. Storage: Store trays horizontally on flat surfaces with timber supports at intervals of about 1 meter, protecting them from moisture and sunlight.

Tools and Equipment: Verify that all tools comply with project requirements and are suitable for the tray type being installed.

Installation Procedure

Mounting and Support: Trapezoidal trays should be self-supporting or fixed to steel/concrete structures using standard steel shapes or self-drilling dowels. Support spacing is typically 2–3 meters, depending on tray type and load. Alignment and Leveling: Ensure trays are straight, level, and securely connected using appropriate fittings.

Cable Laying: Lay cables neatly, using ties or straps to separate by voltage and function. Leave slack for expansion or future adjustments. Grounding and Bonding: Metal trays must be properly grounded with bonding jumpers across sections to maintain electrical continuity.

Covers and Protection: Use covers in areas with high mechanical risk. Covers should match tray material and be secured with manufacturer-recommended clips. Inspection and Documentation: Conduct a final walkthrough to check for loose clamps, misalignment, or overfilled sections.

Label cables and maintain updated documentation for future audits.

Safety and Standards

Follow IE

C 61537, NEC Article 392, and local building and fire codes. Ensure trays are installed to carry the specified load, avoid water retention, and allow proper ventilation to prevent overheating.

Maintenance

Routine inspections should check for corrosion, loose wires, or damaged clamps. Proper preventive maintenance extends tray lifespan and ensures reliable cable management. By adhering to these guidelines, trapezoidal cable trays in El Salvador can be installed safely, efficiently, and in compliance with international and local standards, ensuring long-term performance and protection of electrical systems.
