Which type of cable provides better protection against physical damage when installed in exposed locations?

• A. NM cable
• B. Conduit-protected cable
• C. Low-voltage cable
• D. Flexible cable

Answer: (B)

Conduit-protected cable is specifically designed to offer robust protection against physical damage, making it the preferred choice for exposed installations. When cable is installed in areas where it may be subjected to impact or other forms of physical stress, having an additional layer of protection is crucial. Conduit serves as this protective barrier, helping to safeguard the wiring inside from external forces such as accidental strikes, abrasions, or environmental factors. In addition to offering physical protection, installing cable within conduit can also provide a level of insulation and reduce the risk of electrical interference, which can be particularly valuable in scenarios where multiple cables are run close together. This additional layer of security helps ensure long-term efficiency and safety of the electrical installation in exposed locations.
