Article 240 in the National Electrical Code ensures what aspect of electrical systems?

• A. Grounded Conductors
• B. Feeders
• C. Overcurrent Protection
• D. Electrical Installations

Answer: (C)

Article 240 of the National Electrical Code specifically addresses overcurrent protection, which is essential for the safety and reliability of electrical systems. The article outlines the requirements for protecting conductors and equipment from the damaging effects of overcurrent, which can occur due to overloads or short circuits. Proper overcurrent protection is crucial for preventing electrical fires, equipment damage, and potential hazards to individuals handling electrical systems. This article provides guidelines on selecting appropriate overcurrent protection devices, such as circuit breakers and fuses, based on the characteristics of the electrical system, including conductor sizes, load calculations, and the specific installation environment. Ensuring that electrical systems are equipped with suitable overcurrent protection mechanisms is a vital component in maintaining safety standards and compliance with NEC regulations.
