What is the general purpose of 300.4 in the NEC?

Explanation:
The general purpose of 300.4 is to protect electrical conductors from physical damage. When conductors are concealed or exposed in locations where they could be damaged—by nails, screws, or other objects—the code requires protective measures such as enclosing them in conduit or raceways or using guards. This safeguards both the insulation and the people nearby, reducing the risk of shorts, shocks, or fires. The idea isn’t that metal raceways are always required (other protective methods can be used), nor is it about grounding requirements, and open conductors in unprotected spaces like attics aren’t allowed when they could be damaged.
