What does NEC Article 240 primarily address?

NEC Article 240 is focused on overcurrent protection, which is essential for the safe operation of electrical systems. It outlines the general requirements for devices and methods that protect conductors and equipment from damage caused by excess current. The article specifies the types of overcurrent devices that can be used, their ratings, and the conditions under which they should be installed. This ensures that overcurrent protection systems effectively shield electrical installations from faults that could lead to overheating, equipment failure, or fire hazards.

Overcurrent protection is a fundamental aspect of electrical safety, and understanding these requirements is crucial for electricians to ensure compliance with the National Electrical Code. This not only contributes to the safety of the installation but also ensures proper functionality of electrical systems.
