Which section of the NEC® indicates that outlet and device boxes must be deep enough to prevent damage to conductors?

The National Electrical Code (NEC®) outlines specific requirements for electrical installations to ensure safety and functionality. The correct choice, which refers to the depth of outlet and device boxes, is found in Section 314.24.

This section addresses the need for boxes to be adequately sized to accommodate the conductors without causing any damage. It specifies that the box depth must allow for safe bending and fitting of conductors, ensuring they are protected from abrasion or crushing that could occur if the boxes are not sufficiently deep. This helps to prevent potential hazards such as short circuits or electrical fires that could arise from improperly installed or stressed conductors.

Understanding the guidelines provided in Section 314.24 is crucial for any electrician or contractor, as it lays the foundation for safe and compliant electrical installations. This provision ultimately promotes reliability and minimizes risks associated with improper electrical setup.
