Which statement about Open harness wires is true?

• A. The wires in an Open harness have a thicker insulation wall and no protective jacket.
• B. The wires in an Open harness have a thinner insulation wall and a protective jacket.
• C. The wires in an Open harness have thicker insulation and a jacket.
• D. The wires in an Open harness are shielded by metal.

Answer: (A)

Open harness wiring is designed so the conductors aren’t enclosed by a single outer protective jacket. Because there’s no common jacket around the bundle, each conductor relies on thicker insulation to protect against wear, moisture, and environmental exposure on its own. That’s why the true statement describes wires with thicker insulation and no protective jacket. The other options describe a jacket around the harness or shielding, which isn’t characteristic of an open harness.
