Price of power cables inside enclosed cable trays

The cost of power cables inside enclosed cable trays varies widely, typically ranging from $1 to $10 per foot for standard industrial cables, with enclosed tray systems adding $20–$100 per meter depending on material and size.

Factors Affecting Price

1. Cable Type and Rating Power cables used in enclosed trays are usually Tray Cable (TC) or Metal-Clad (MC) cables, rated for 600 volts and designed for industrial or commercial use. TC cables can be flame-retardant, crush-resistant, and impact-resistant, with ER (exposure-rated) variants allowing short unsupported runs outside the tray . Prices vary by conductor size, insulation type, and voltage rating, typically $1–$5 per foot for smaller gauge cables and $5–$10 per foot for larger multi-conductor or armored cables. 2. Enclosed Cable Tray Material and Size Enclosed cable trays are made from galvanized steel, stainless steel, or heavy-duty GI plates, providing protection against physical damage, dust, and moisture . Standard widths range from 100 mm (10 cm) to larger sizes for high-density cabling. Costs depend on material, load capacity, and length, generally $20–$50 per meter for standard steel trays and up to $100 per meter for heavy-duty or stainless steel trays. 3. Installation Considerations Installation costs include labor, supports, splicing, and securing cables at intervals (typically every 6 feet for TC-ER cables). Industrial environments may require additional safety measures, walkable trays, or custom layouts, which can increase total cost. Labor and installation typically add $10–$30 per meter depending on complexity.

Typical Cost Example

For a medium-scale industrial project using 10 cm wide enclosed trays with 600V TC cables:

• Cable cost: $2–$5 per foot
• Tray cost: $25–$50 per meter
• Installation: $15–$25 per meter
• Total: Approximately $50–$100 per meter of installed cable tray system including cables.

Summary

The total price of power cables inside enclosed cable trays depends on cable type, tray material, size, and installation complexity. For budgeting, expect $50–$100 per meter for a standard industrial setup, with higher costs for heavy-duty, stainless steel, or high-capacity trays. Always verify UL listing, NEC compliance, and manufacturer specifications to ensure safety and durability .
