What is the primary requirement for box supports according to Article 314?

The primary requirement for box supports according to Article 314 of the National Electrical Code (NEC) is that boxes must be securely supported and allow safe operation. This stipulation is critical because it ensures the integrity and structural stability of electrical boxes, preventing hazards such as disengagement due to weight or movement. Secure support reduces the risk of damage to the conductors and connections contained within the boxes, promoting both safety and compliance with the code.

Proper support is essential for maintaining the functionality of the electrical system, especially in installation scenarios where boxes may be exposed to various stresses, such as pulling forces from cables or environmental conditions. This requirement helps to ensure that the electrical connections remain reliable over time, safeguarding against potential electrical faults that can arise from improperly supported boxes.

Other options, while they may relate to different aspects of electrical installation or material specifications, do not represent the core requirement focused on safety and functionality as outlined in Article 314. For instance, painting boxes, although a consideration for aesthetics or corrosion resistance, is not a primary safety or support requirement. Similarly, while fire resistance is important for materials, the NEC does not specifically mandate that all boxes must be made of fire-resistant materials under Article 314. Lastly, while boxes can be installed at various
