The National Electric Code (NEC) is enforced in?

The National Electric Code (NEC) is a set of standards that governs the installation and maintenance of electrical systems in the United States. Its enforcement is determined by individual states and municipalities that choose to adopt it. When a state or local government adopts the NEC, it becomes the standard for electrical work in that jurisdiction, thus ensuring safety and reliability across electrical installations.

This means that while the NEC serves as a guideline, its enforcement is not uniform across the country and varies based on local laws and regulations. Some areas may choose to follow the NEC closely, while others may implement their own standards or modifications. Therefore, the accurate understanding of the NEC's scope is that it is enforced in states and municipalities that have officially adopted it, reflecting the collaborative nature of such regulatory practices.
