Which four elements are included in ICEA cable coding?

• A. Family/design, insulation, conductor, sheath
• B. Family/design, insulation, jacket, shield
• C. Insulation, conductor, armour, jacket
• D. Family/design, sheath, color code, conductor

Answer: (A)

ICEA cable coding describes a cable by four parts from inside out: family/design, insulation, conductor, and sheath. The family/design identifies the overall cable category and intended usage, guiding the general construction and standards that apply. The insulation specifies the dielectric material around the conductor, which determines voltage and temperature ratings as well as flexibility and chemical resistance. The conductor indicates the material and form of the conductive path (usually copper or aluminum, solid or stranded), affecting current-carrying capacity and mechanical behavior. The sheath is the outer protective layer around the insulation and conductor, providing environmental and mechanical protection. These four elements together capture the essential construction details used by ICEA, whereas other terms like shield, armour, jacket, or color code are not part of this four-element coding scheme.
