Which NEC® section states that outlet and device boxes must be deep enough to prevent conductor damage during installation?

The correct section addressing the requirement for outlet and device boxes to be deep enough to prevent conductor damage during installation is indeed 314.24. This section outlines the importance of ensuring that conductors are protected from physical damage, which can occur if they are pinched, crushed, or subjected to undue stress during wiring installations.

It specifically emphasizes maintaining a minimum depth in outlet and device boxes to accommodate the conductors without causing harm. This provision is critical for ensuring both the safety and longevity of the electrical installation, as it helps to avoid potential short circuits or failures due to conductor damage.

Understanding the requirements in this section is vital for electricians when selecting and installing boxes, as it directly impacts the reliability and safety of electrical systems.
