What does NFPA 70, the national electric code, advise technicians about?

NFPA 70, also known as the National Electrical Code (NEC), provides comprehensive guidelines and standards for the safe installation of electrical wiring and equipment. It is primarily concerned with ensuring that electrical systems are installed in a manner that minimizes the risk of electrical hazards, including shocks, fires, and equipment failures. Technicians must follow these standards to comply with regulations and ensure safety in electrical installations.

While managing fire-related emergencies, performing inspections, and conducting fire drills are essential aspects of fire safety and overall building operations, they fall under other guidelines and codes. These other practices are typically governed by different sections of the NFPA codes or other safety organizations, not specifically by NFPA 70. Therefore, the focus of NFPA 70 is distinctly on installation practices, which is why this is the correct answer.
