Only ___ are permitted to perform construction, maintenance, and interconnection requirements for wind electric systems found in the NEC.

Only ___ are permitted to perform construction, maintenance, and interconnection requirements for wind electric systems found in the NEC.

• A. Certified Electrical Engineers
• B. Wind Electric System Manufacturers
• C. Qualified Persons
• D. Certified Wind Electric System Engineers

Answer: (C)

The idea behind this NEC rule is that who performs wind electric system work must have the proper safety knowledge and practical ability to do it safely. The NEC defines a “qualified person” as someone who has the skills and knowledge to properly construct, operate, and maintain electrical equipment and who has received safety training to recognize and avoid hazards. For wind systems, that means on-site workers—such as appropriately trained electricians or technicians—are permitted to carry out construction, maintenance, and interconnection tasks because they understand the specific hazards, wiring methods, protection requirements, and interconnection procedures involved. The other options don’t align with how the NEC defines who may perform such work; they refer to titles or roles that aren’t the code’s defined qualification for performing these tasks. So the permissible designation is qualified persons.
