What does NEC Article 240 address?

NEC Article 240 specifically addresses overcurrent protection requirements for circuits. It provides guidelines on how to protect conductors and devices from damage due to excessive current flow, which could cause overheating and potential fire hazards. This article outlines the necessary specifications for the use of protective devices such as fuses and circuit breakers, detailing their ratings, installation practices, and how they should be coordinated within an electrical system to ensure safety and compliance with the National Electrical Code.

The focus on overcurrent protection is critical in electrical installations to maintain safe operation under normal and fault conditions. By ensuring that the overcurrent protection devices are properly rated and selected, electronic systems can effectively mitigate the risks associated with short circuits, overloads, and other current-related issues. This understanding is essential for adhering to electrical safety standards and practices.
