The National Electrical Code (NEC) takes a comprehensive approach to safety by outlining both general and specific rules that govern electrical installations. This framework ensures that electrical systems are designed and implemented in a manner that minimizes risks, promotes safety, and accommodates various scenarios that electricians may encounter in the field.

By incorporating both general principles applicable to all electrical work and specific rules tailored to different installations, the NEC addresses safety comprehensively. This structure allows for flexibility while ensuring that essential safety measures are maintained, adapting to new technologies and practices over time. This dual focus is crucial for fostering consistent safety standards across diverse electrical applications and environments.

Other approaches, such as emphasizing maximum installation requirements or standardizing all components, could limit the adaptability and responsiveness to various situations encountered in real-world applications. Focusing solely on proper grounding techniques, while important, does not encompass the entirety of safety considerations addressed by the NEC.
