NEC Commercial Electrical Practice Test

This CODE specifically covers installations used by which utility?

1. Water

2. Gas

3. Waste management

4. Electric

The correct answer is: Electric

The National Electrical Code (NEC) specifically governs installations related to electrical systems and provides comprehensive guidelines and standards for electrical wiring in various applications. The NEC's primary focus is on ensuring safety in the installation and maintenance of electrical wiring and equipment under the jurisdiction of the electric utility providers. The Code addresses topics such as proper grounding, overcurrent protection, and safe distances between electrical installations and other systems, which are all critical for preventing electrical hazards. The NEC is regularly updated to reflect advancements in technology and changes in safety practices, ensuring that the installations used by electric utilities meet the current national safety standards. While there are codes that relate to water, gas, and waste management systems, those fall under different regulations and standards, which are not part of the NEC. Therefore, when discussing installations specifically used by a utility, the focus is solely on electric utilities, making this answer accurate.
