In terms of grounding principles, what is the primary purpose of the NEC®?

The primary purpose of the National Electrical Code (NEC®) is to promote safety from electrical hazards. This code sets the foundational standards intended to protect people and property from electrical risks such as shock, fire, and overloading. Grounding and bonding are critical components of electrical safety, as they help to ensure that any fault currents are effectively channeled away from equipment and individuals, reducing the risk of injury or damage.

The NEC defines requirements for properly grounding electrical systems, enabling safe operation under normal and fault conditions. By focusing on safety, the NEC plays a vital role in creating standards that must be adhered to by electricians and other professionals in the field, thereby minimizing the potential for electrical accidents in residential, commercial, and industrial applications.
