The statement 'The wires in a protective harness have a thicker insulation wall and no protective jacket' is true or false.

• A. True
• B. False
• C. Not stated
• D. Cannot be determined

Answer: (B)

The key idea is that a protective harness protects wiring by enclosing the entire bundle in an outer protective jacket or sheath, rather than relying on thicker insulation on each conductor alone. Each wire typically has its own standard insulation, and then the conductors are gathered and covered by a protective jacket around the bundle. This outer jacket provides abrasion resistance, moisture and chemical protection, and helps prevent damage from movement and vibration. Saying the wires have thicker insulation and no protective jacket would leave the bundle vulnerable to wear and environmental exposure, which is not how harnesses are designed to protect wiring. Therefore, the statement is false.
