Which type of services are strictly prohibited from using ring type meter bases?

The use of ring type meter bases is specifically associated with certain regulations and standards within the electrical industry. New permanent services are generally prohibited from using ring type meter bases due to safety concerns and the need for better protection against environmental factors and potential tampering. These meter bases can present challenges in accurately measuring electricity consumption and can also lead to difficulties in maintenance and access for utility workers.

In the context of permanent services, standards typically call for meter bases that provide reliability and safety, ensuring that the equipment can handle the load and conditions in which it operates. This is particularly important for permanent installations where longevity and adherence to electrical codes must be prioritized. Therefore, the restriction on using ring type meter bases for new permanent services underscores the industry's commitment to safety, accuracy, and compliance with established electrical standards.
