What should individual meter socket enclosures be for the voltage and ampacity of the service?

Individual meter socket enclosures must be listed and rated for the voltage and ampacity of the service to ensure they meet the required safety and performance standards. "Listed" means that the meter socket has been tested by a recognized testing laboratory and meets specific criteria for safety and performance. This is crucial to prevent electrical hazards and ensure reliable operation.

Being "rated" means that the enclosure can safely handle the specified voltage and current levels without risk of overheating, failure, or creating unsafe conditions. The combination of being properly listed and rated ensures that the meter socket can safely accommodate the electrical load it will be subjected to, which is vital for both the utility service provider and the end-user.

Other options, while they may represent good practices in electrical installations, do not specifically address the requirements set forth for meter socket enclosures regarding their capability to handle voltage and ampacity. For instance, insulation and grounding are certainly important for safety, but they do not pertain directly to the listing and rating of the enclosures. Similarly, painting or labeling is not a requirement that relates to function but may pertain to identification and aesthetics, rather than compliance with the NEC standards. Certification and approval can also apply, but "listed and rated" directly aligns more closely with the
