Mesh cable trays in Morocco can be installed efficiently by following proper preparation, support, and connection procedures to ensure safety, ventilation, and compliance with standards.

Preparation and Material Handling

Before installation, inspect all received materials to ensure they match approved specifications and are free from damage or corrosion. Store trays horizontally on a flat surface with timber supports at intervals of about one meter, protecting them from moisture and direct sunlight . Verify that all tools, fasteners, and accessories comply with project requirements and local electrical codes.

Layout and Planning

Review the approved shop drawings to determine tray routes, lengths, bends, and junctions . Consider the load capacity, cable quantity, and environmental conditions when selecting the appropriate mesh tray type. Moroccan installations may require corrosion-resistant finishes such as galvanized steel or stainless steel depending on humidity and exposure .

Mounting and Support

Mesh cable trays can be mounted on walls, ceilings, or floors using brackets, hangers, or Strut rails . Maintain proper spacing between supports, typically every 1.5–2 meters for standard spans, and ensure trays are level. Use suspension brackets for overhead installations and wall brackets for vertical runs. Ensure that bends, branches, and exits are planned to allow easy cable feeding in multiple directions .

Joining and Bending

Sections of mesh trays are joined using connectors or snap-in systems such as the Magic connector or Faslock, which allow tool-less assembly and secure connections . For bends or T-junctions, the mesh can be cut and bent on-site using appropriate cutters, taking care to smooth sharp edges to prevent cable damage . Ensure that all joints are mechanically stable and aligned with the tray route.

Cable Installation

Feed cables into the trays while maintaining proper separation of power and data lines to reduce interference. The open mesh design allows for ventilation and heat dissipation, minimizing temperature rise in cables . Avoid overloading trays beyond their rated capacity and secure cables with ties or clamps as needed.

Safety and Compliance

Wear protective gloves to handle sharp edges and follow local electrical codes and international standards such as IEC 61537. Ensure trays are grounded if required and verify that all fasteners and supports are tightened. Regularly inspect the installation for alignment, stability, and corrosion protection .

Maintenance

The open structure of mesh trays allows for easy visual inspection and cleaning, reducing dust and water retention. Periodic checks should ensure that supports remain secure and that cables are properly routed without sagging or damage . By following these steps, Moroccan mesh cable trays can be installed safely, efficiently, and in compliance with both local and international standards, ensuring long-term reliability and ease of maintenance.
