Which of the following outlines installation standards for electrical work?

The National Electrical Code (NEC) is the definitive code that outlines installation standards for electrical work. It provides comprehensive guidelines for the safe installation and maintenance of electrical systems in residential, commercial, and industrial settings. The NEC is regularly updated to incorporate the latest safety practices and technological advancements, ensuring that electrical installations are performed safely and effectively.

In contrast, the National Safety Council Guidelines primarily focus on general safety practices rather than specific electrical installation standards. The Environmental Protection Agency Standards are concerned with environmental protection and compliance, which do not directly relate to the installation standards of electrical systems. The International Building Code, while it covers a wide range of construction standards including structural integrity and safety, does not specifically specialize in the electrical installation requirements that are detailed in the NEC.

This specialized focus on electrical standards makes the National Electrical Code the correct choice for outlining installation standards in electrical work.
