What is the primary reason to route wiring through conduit in areas where damage could occur?

• A. To protect it from potential damage
• B. To keep it hidden
• C. To increase air flow
• D. To reduce cost

Answer: (C)

The main idea is that wiring in areas where damage could occur must be protected by conduit to shield the conductors from physical damage. Conduit acts as a tough outer sleeve that resists impact, abrasion, and environmental exposure (like moisture or fluids) and helps prevent insulation damage that could lead to shorts or fires. In aircraft and other machinery, vibrating components, rubbing against surfaces, and potential contact with fuel or chemicals make this protection essential for safety and reliability.

Other reasons that might be tempting—concealing wiring, increasing air flow, or cutting costs—don’t apply here. Conduit isn’t used to hide wires, it doesn’t improve airflow, and it typically adds material and installation costs, whereas its primary purpose is to safeguard the electrical system.
