Which term describes an arrangement of insulated conductors bound together for use in a specific equipment?

• A. Cable assembly
• B. Wire loom
• C. Wiring harness
• D. Cable bundle

Answer: (C)

A wiring harness is a grouped set of insulated conductors bound together to form a single, installable unit that fits inside equipment. This binding and organization makes routing, installation, and maintenance easier, and it can include protective sleeving, connectors, and terminations tailored to the equipment’s layout and interfaces.

This differs from a cable assembly, which is a set of conductors terminated with connectors for a specific installation but not necessarily arranged as a reusable, mounted bundle. A wire loom refers to the protective conduit or sheath used to channel and shield wires, not the assembled bundle of conductors itself. A cable bundle is simply several wires tied or grouped together without the integrated structure, protection, and connection points that a harness provides.
