Abstract: An electrical energy meter is provided with snap fit interlocking parts that eliminate the need for screws or fasteners. The current sensor, located within the meter, has a plurality of current conductors and a notched blade attached to each current conductor that functions as an interlocking component to the meter base without the need for additional fasteners. A circuit board used by the meter is attached to a plurality of integral posts projecting from the base and the periphery of the circuit board has a pair of spaced notches for connection to the ends of a radial communications antenna without the requirement for additional hardware.
