Which protection method is used for NM cable located where it could be damaged, such as in a garage?

• A. IMC conduit
• B. EMT conduit
• C. PVC conduit
• D. Flexible metal conduit

Answer: (A)

When NM cable could be damaged, it must be protected by a raceway to shield it from physical harm. In spaces like a garage, that protection needs to be sturdy and reliable, so metal conduit is used to enclose and guard the cable. IMC conduit provides strong mechanical protection with a rigid metal wall, making it well-suited for areas where impact or abrasion is possible. It’s tougher than EMT and lighter than rigid metal conduit, giving you solid protection without the heaviness of the largest option. This makes it a practical choice for protecting NM cable in a garage, where vehicles or tools might come into contact with the wiring path. Other options offer protection to some extent, but they don’t match IMC in terms of durability for this scenario. EMT is thinner-walled and less protected against damage, PVC conduit is non-metallic and can be less resistant to physical abuse in a high-traffic or impact-prone area, and flexible metal conduit isn’t ideal for long, straight runs where robust protection is needed.
