What information is contained in the NESC?

• A. Outside plan codes
• B. Inside wiring standards
• C. Cable color codes
• D. Grounding procedures

Answer: (A)

Think of the NESC as the safety standard for electrical work outdoors—overhead and underground lines outside buildings. It provides the rules used when planning and coding outdoor installations, i.e., outside plan codes. The NESC focuses on outdoor environments and how outdoor electrical systems are designed, protected, and maintained for safety. Inside wiring standards, color codes, and many specific grounding procedures belong to other codes and standards, so the information most characteristic of the NESC is the framework for outdoor plans.
