What is the main purpose of the National Electrical Code (NEC)?

The main purpose of the National Electrical Code (NEC) is to establish standards for electrical safety. This comprehensive set of guidelines is designed to ensure that electrical installations are safe for both people and property. It provides minimum safety requirements to reduce the risk of electrical hazards, such as shock, fire, and equipment damage. By creating a uniform standard that can be followed across various jurisdictions, the NEC facilitates safe electrical practices, ensuring consistency and protection in electrical design and installation.

While the other options touch on aspects related to electrical work, they do not capture the primary focus of the NEC. For instance, the code does not specify software standards, regulate material costs, or directly monitor energy consumption. Instead, its emphasis is firmly on safety to protect individuals and infrastructure from the dangers associated with electrical systems.
