Description

UL 1277 TC-ER Tray Cable – 600V 90°C Crush & Impact Resistant XLPE/PVC Power Cable (NEC 318/340 Compliant)

UL 1277 Type TC-ER Tray Cable

Product Overview

This UL 1277 certified Type TC-ER cable delivers robust power and control solutions for industrial cable tray systems. Engineered with XLPE or PVC insulation and crush-resistant construction, it meets NEC Article 318/340 requirements for 600V applications in dry (90°C) and wet (75°C) environments. Ideal for hazardous locations and demanding industrial installations.

Engineering Selection Guide

  1. Insulation Selection:

    • XLPE (XHHW): Higher temp (90°C), better dielectric strength

    • PVC (THHN): Cost-effective for standard environments

  2. Shielding Requirement:

    • Essential for VFD/motor circuits >100HP

  3. Hazardous Area Compliance:

    • Verify Div 2 gap distances per NEC 501

  4. Mechanical Protection:

    • Use impact-resistant variant for high-traffic areas

  5. Bending Radius:

    • Minimum 20× overall diameter
