A solid-state electricity meter uses a sensor to measure a current supplied to a load. In one aspect, the electricity meter housing includes a meter base, a register cover, and a meter cover. The meter base includes a plurality of meter cover lock lock notches disposed about a periphery of the meter base. The register cover includes a plurality of secure ramps disposed on a base portion thereof, each secure ramp having a ramped portion along one side and a land portion. The meter cover includes a plurality of locking tabs corresponding to the meter cover lock notches and further includes a plurali ty of meter cover locks corresponding to the secure ramps. Upon insertion of th e meter cover locking tabs into the meter base lock notches and rotation of th e meter cover in a predetermined clockwise or counterclockwise direction, the meter cover locks engage the corresponding secure ramps, thereby biasing the meter cover locking tabs against the backside of the meter base to provide a secure connection.
