What standard must be adhered to for the safe installation of electrical wiring?

The National Electrical Code (NEC) is the correct standard to adhere to for the safe installation of electrical wiring. The NEC provides a comprehensive set of regulations intended to protect people and property from electrical hazards. It covers the installation of electrical conductors, equipment, and raceways, and dictates standards for wiring methods, grounding, and bonding practices.

By following the NEC, electricians ensure that electrical installations are safe, reliable, and compliant with recognized standards. It is widely adopted across the United States, and familiarity with its provisions is essential for anyone involved in electrical work.

While other codes, such as the International Electrical Code (IEC), Local Building Codes (LBC), and Federal Safety Code (FSC), may also play a role in specific regions or situations, the NEC is the primary national standard that sets the benchmark for safe electrical installations in most contexts.
