What does NEC stand for?

The acronym NEC stands for National Electrical Code, which is a set of standards for electrical installation and safety in the United States. This code is essential as it outlines the minimum requirements for safe electrical wiring and equipment, helping to prevent fires and electrical hazards. The NEC is updated periodically, and it serves as a guideline for electricians, contractors, and inspectors to ensure that electrical systems are designed and constructed safely. It is widely adopted across various states, including Michigan, and serves as an important reference for maintaining electrical safety and compliance with local regulations.

The other options do not accurately represent established terms in the electrical field or are not related to electrical safety standards in the same way that the National Electrical Code is.
