Article 110.22 emphasizes the importance of what in regards to circuit protection?

Article 110.22 of the National Electrical Code (NEC) emphasizes the importance of using proper circuit protection to ensure safe operation. This aspect is fundamental because circuit protection devices, such as breakers and fuses, are designed to protect electrical circuits from overloads, short circuits, and other fault conditions that can lead to equipment damage, fire hazards, or electric shock.

Using appropriate circuit protection contributes to the overall safety and reliability of electrical installations, ensuring that they comply with established safety standards. Proper circuit protection also facilitates the working of the electrical system, allowing it to operate effectively under normal conditions while safeguarding it against unforeseen incidents that could potentially cause malfunction or danger.

In contrast, options that focus on low-cost materials, minimal supervision during installation, or rapid installation do not align with the principal intention of Article 110.22, which prioritizes safety and reliability over economic or expediency considerations. Prioritizing cost-cutting or rushing through installation can compromise the effectiveness of circuit protection and increase the risk of electrical failures.
