Final answer:
Electric utility installations and equipment under the exclusive control of the utility do not have to conform to the National Electrical Code. However, they do have to conform to the utility's own internal standards and regulations.
Step-by-step explanation:
Electric utility installations and equipment under the exclusive control of the utility do not have to conform to the National Electrical Code. However, they do have to conform to the utility's own internal standards and regulations.
While the National Electrical Code (NEC) sets the safety standards for electrical installations in general, utilities may have their own specific guidelines and requirements that are tailored to their operations and infrastructure. These internal standards ensure that the utility's installations and equipment are in compliance with industry practices and meet the necessary safety, reliability, and performance standards.
For example, a utility may have specific guidelines for the design, construction, and operation of their power distribution systems, including requirements for equipment protection, grounding, and protection against faults. These internal standards are developed based on years of experience, research, and industry best practices to ensure the safe and efficient operation of the utility's infrastructure.
