A standard cable tray bonding jumper typically costs between $5 and $15 per unit, with bulk purchases reducing the per-unit price.

Price Overview

The cost of a cable tray jumper depends on several factors, including material, size, design, and durability features such as weather resistance or corrosion protection . Standard jumpers made from tin-plated copper or aluminum generally fall within the $5 to $15 range per unit in the USA . Bulk orders can significantly lower the per-unit cost, making them more economical for large projects .

Material and Size Considerations

• Tin-plated copper: Common for grounding and bonding, offering good conductivity and corrosion resistance .
• Aluminum: Lightweight and cost-effective, suitable for certain installations .
• Length and gauge: Longer or thicker jumpers, such as 16-inch tinned copper braids or #6 AWG straps, may cost more due to increased material usage .

Installation and Standards

Cable tray jumpers must comply with National Electrical Code (NEC) and OSHA standards to ensure proper grounding and safety . Installation typically involves bolting lugs to the tray channel, and optional lengths or colors may be available for specific applications .

Practical Tips

• For small projects, purchasing single units is convenient but slightly more expensive per unit.
• For large-scale installations, buying in bulk reduces costs while maintaining quality.
• Consider durability features like flame-retardant insulation or resistance to oil and chemicals if the environment demands it . By understanding these factors, you can select a cable tray jumper that balances cost, safety, and performance for your specific project needs .
