Is a cable tray the same as a cable tray

Optical network knowledge brief Published 26 Oct 2024

Prepared for preliminary research by the COETZER OPTICAL knowledge desk. Confirm compatibility, loss budgets and installation requirements against current standards and product documentation.

Tray cable (Type TC) is a type of electrical cable, while a cable tray is the physical support system that carries such cables; they are not the same thing.Detailed ExplanationWhat Tray Cable Is

Tray cable (Type TC) is an electrical cable specifically designed and listed for installation in cable trays. It is built to meet UL 1277 requirements and NEC Article 336, offering flame resistance, mechanical protection, and suitability for industrial environments. Key points:

  • “TC” literally stands for tray cable.
  • Used for power, control, and instrumentation circuits.
  • Includes variants like TC-ER, TC-LS, and TC-CIC.
What a Cable Tray Is

A cable tray is a structural support system—such as ladder, perforated, or wire-basket trays—used to route and support cables throughout a facility. It is not a cable but the infrastructure that holds cables. Key points:

  • Open, rigid support system for routing cables.
  • Allows visibility, accessibility, and easier maintenance.
  • Comes in multiple types (ladder, perforated, basket).
Why They're Confused

The terms sound similar, and tray cable is intended for use in cable trays. However:

  • Tray cable = the cable itself.
  • Cable tray = the structure that supports cables.
Summary

Tray cable and cable tray serve complementary but distinct roles: one is the wiring method, and the other is the physical support system.
