The National Electric Code (NEC) is a comprehensive set of safety regulations and guidelines developed by the National Fire Protection Association (NFPA) to protect people and property from electrical hazards. It is used in more than 80 countries worldwide, including the United States.

The NEC covers everything from wiring choices, grounding practices, circuit design safety specifications, and the placement of electrical components. It also provides information on voltage drop calculations, overcurrent protection requirements, and other electrical system design considerations. In addition to outlining protective measures for working with or near electricity, the NEC also addresses environmental concerns such as water damage from floodwaters or ice storms.

The NEC is regularly revised and updated to keep up with changing standards for safety and technology. It is published on an annual basis but may be supplemented with interim changes throughout the year as well. As such, it is important that licensed electricians stay up-to-date on any alterations made to the code — especially those made within their local jurisdiction — in order to stay compliant with regulations and ensure safe installations at all times.
