As utilities move toward two-way communications for meters and remote meter reading, the opportunity for inspection of meter sockets is expected to decline. The interval between site visits by utility personnel could be more than 100 times longer than current monthly schedules.
NEMA recommends that all existing meter sockets be thoroughly inspected when new electrical meters are installed. Inspection criteria should include (but not be limited to) indications of excessive heating, corrosion, loose connections or components, deformed socket jaws, broken components, failed insulation, damage due to ground settling or vandalism, or any exposed live parts. If any damage is discovered, the meter socket should be replaced by a qualified electrician immediately.
