Which statements are true regarding the protection of nonmetallic sheathed cable from physical damage?

When discussing the protection of nonmetallic sheathed cable from physical damage, it is important to recognize how these cables are designed to be used in various environments and what specific measures are required for their protection. The correct answer indicates that both statements I and II are true, underlining significant aspects of safety and code compliance.

Nonmetallic sheathed cables, often referred to as NM cable (like Romex), are typically used in residential wiring and can be vulnerable to physical damage in certain situations. Therefore, various means must be employed to protect these types of cables. This includes ensuring that the cable is not exposed to potential hazards or that it is installed in a manner that minimizes the risk of impact or abrasion.

Both statements affirm appropriate safety practices associated with the protection of these cables. One common method of protection includes the use of physical barriers, such as raceways or conduits, to shield the cable in areas where it might be subjected to impact. Additionally, running cable through hollow walls, where it is less susceptible to damage, is a typical best practice.

By confirming that both statements are accurate, it reinforces the idea that proper care and precautions are crucial when working with nonmetallic sheathed cable to maintain safety and compliance with electrical codes.
