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. A cutout in the cover plate provides access and visibility for the sealing wire. Authorized bypass connections for the meter to permit its removal without disturbing service are facilitated by horn terminals whose ends project beyond the meter periphery to permit facile connections thereto.
