Installing 10-foot mesh cable tray sections alone may seem challenging at first, but with proper planning, the right tools, and a clear understanding of NEC requirements, contractors can complete the job safely and efficiently. Wire mesh trays are specifically designed to simplify installation—they are lightweight, field-modifiable, and easier to maneuver than traditional ladder or solid-bottom trays. This makes them an excellent solution for solo installations in commercial offices, industrial facilities, smart buildings, and data centers. 

One of the biggest advantages of wire mesh tray systems is their flexibility. Sections can be cut and shaped on-site to accommodate corners, elevation changes, and unique pathway layouts without requiring specialized fabrication. Their lighter weight reduces physical strain during overhead installations, and prefabricated 10 ft. sections allow for faster pathway coverage with fewer splice connections. 

Key Takeaways 

  • 10-foot mesh trays are lightweight and manageable for solo installation. 
  • Proper support spacing ensures structural integrity. 
  • NEC Article 392 requires bonding and grounding continuity. 
  • Maintain 50% fill capacity to improve airflow and scalability. 
  • Tray-rated power and control cables simplify compliance. 
  • Powder-coated trays reduce contamination risks and enhance durability. 

 

Why 10 Ft. Mesh Sections Are Contractor-Friendly 

Black powder-coated 10 ft. mesh trays are designed for: 

  • Lightweight handling 
  • Easy field cutting and bending 
  • Strong mechanical support 
  • Improved airflow 
  • Simple bonding continuity 

The powder-coated finish also reduces zinc whisker risk while providing corrosion resistance and a professional appearance in exposed ceiling installations. 

Step-by-Step Installation Guide 

Step 1: Pre-Plan the Route 

Before lifting a tray section: 

  • Confirm pathway alignment 
  • Identify support locations 
  • Verify support spacing per manufacturer specs 
  • Check separation requirements for power vs low-voltage cables 

Proper planning reduces rework and installation time. 

Step 2: Install Supports First 

Whether using wall brackets, trapeze supports, or threaded rod systems: 

  • Ensure supports are level 
  • Anchor securely into structural members 
  • Verify load ratings 

Support spacing directly impacts load capacity and long-term tray integrity. 

Step 3: Lift and Set the 10 ft. Section 

When working solo: 

  • Lift one end onto the first support 
  • Temporarily secure it before positioning the opposite end 
  • Use clamps to hold alignment during fastening 

Mesh trays are lighter than solid-bottom trays, making solo handling manageable. 

Step 4: Bond Splice Connections 

Under NEC Article 392: 

  • All tray sections must maintain electrical continuity 
  • Splice plates must be mechanically tight 
  • Bonding jumpers should be installed where required 

Proper bonding ensures fault current has a safe path to ground. 

Step 5: Verify Grounding 

Metallic trays must: 

  • Be electrically continuous 
  • Connect to the building grounding electrode system 
  • Use properly sized grounding conductors 

Failure to comply may result in inspection rejection, shock hazards, or equipment damage. 

Step 6: Begin Cable Placement 

Once the tray system is secure and grounded, begin pulling cables based on project needs. 

Power Cables (Primary CTA) 

Higher-voltage power cables demand careful planning to ensure safety, performance, and NEC compliance. Proper spacing and accurate fill calculations are critical to prevent overheating, ampacity derating, and inspection failures. Under NEC Article 392, tray fill requirements are based on cable type, size, and cross-sectional area—making it essential to verify capacity before installation. 

Maintain the recommended 50% fill capacity to allow airflow and future expansion. 

Control Cable (Primary CTA) 

Tray-rated PLTC (Power-Limited Tray Cable) control cables are specifically designed for installation in cable tray systems, making them an excellent choice for industrial automation, manufacturing equipment, and building management systems. Their construction allows for secure routing in open tray environments while supporting NEC compliance. 

Ethernet Cables 

For office networks, PoE lighting systems, wireless access points, and IP camera installations, structured cabling performance is critical. Power over Ethernet (PoE) applications generate additional heat because the same cable carries both data and electrical power. In high-density bundles, this heat can accumulate quickly if airflow is restricted. 

Fiber Optic Cables 

Backbone fiber runs require careful bend radius management to maintain signal integrity and long-term performance. Unlike copper cabling, fiber optic cables are highly sensitive to excessive bending, pulling tension, and compression. Violating minimum bend radius specifications can cause signal loss, microfractures, or permanent damage to the fiber strands. Ensure fiber is supported and not compressed by heavier cables. 

Installation Best Practices for Solo Contractors 

  • Stage materials along the route beforehand 
  • Use temporary supports during alignment 
  • Pre-assemble splice hardware when possible 
  • Maintain 50% tray fill 
  • Inspect bonding at every connection 
  • Confirm grounding conductor sizing per NEC tables 

These practices reduce installation time while improving safety and compliance.

Frequently Asked Questions 

Can one person install a 10-foot mesh tray section? 

Yes. Mesh trays are lightweight and designed for manageable handling with proper support setup. 

Do powder-coated trays still require grounding? 

Yes. All metallic trays must be bonded and grounded per NEC Article 392. 

What is the recommended tray fill percentage? 

Best practice is 50% or less to allow airflow and future expansion. 

Can power and Ethernet share the same tray? 

Yes, but separation requirements may apply depending on voltage and local codes. 

When installed correctly, mesh tray systems deliver long-term reliability, improved airflow, simplified inspections, and easier future expansion. By combining safe installation practices with NEC-compliant grounding and bonding, contractors can complete solo installations efficiently without sacrificing safety, performance, or inspection readiness.
