Abstract:

The following specification describes a meter receptacle assembly utilizing an outer collar to overlap the meter flange base and latched to the cabinet in which the meter is mounted by interlocked tabs and a sealing wire. A trim or cover plate for the cabinet in turn overlaps a flange wall on the collar and is locked to the cabinet to prevent removal of the collar and unauthorized bypass of the meter.
