            Meters Sockets News and Technical Information

            ​Here is a summary of the range of ANSI C12 Standards that NEMA Members work to develop and maintain.

            Meter Socket Adapters

            In light of industry trends such as the integration of distributed solar photovoltaic generation and the installation of backup generators in disaster-prone areas, meter socket adapters are being more commonly used within the service entrance of residential, commercial, and industrial buildings. The purpose of this paper is to educate owners and installers of meter socket adapters on general use applications for these products, as well as design and testing requirements.

            Evaluating Meter Socket Lifespan

            Under ideal conditions, meter socket manufacturers anticipate that meter sockets will have a lifespan of approximately 20-25 years. Because less-than-ideal conditions often surround meter socket installation and operation, NEMA’s Meter Mounting and Test Equipment Section Members recommend that utilities manually inspect sockets as regularly as is economically and operationally practicable.

            There is a range of commonly occurring factors which are likely to reduce socket lifespan. During inspections, utility workers should look for evidence of these factors in the form of discolored (i.e., blue) or darkened connections resulting from over-heating and/or micro-arcing; loose, mismatched or out-of-place electrical connections; or rust on any of the metal components due to corrosion.
