An electricity meter coupled to a load, the load coupled to electrical power lines includes a sensor module having a sensor housing, voltage and current sensors secured within the sensor housing and a service disconnect switch secured within the housing. The voltage and current sensors are operable to receive voltage and current signals representative of voltage and current provided to the load and generate measurements signals therefrom. The service disconnect switch is operable to controllably disconnect and connect the load to the electrical power lines. The meter further includes a removable measurement module including a measurement circuit operable to receive the measurement signals and generate energy consumption data therefrom. The measurement module includes a device for communicating information relating to the energy consumption data. The measurement module is configured to be coupled to the sensor module to connect the measurement circuit to the voltage and current sensors. The sensor housing can include a disconnect switch having an actuator accessible external to the sensor housing, the actuator being inaccessible when the measurement module is coupled to the sensor module. The disconnect switch is operably connected to cause, when actuated, the service disconnect switch to change from the connected state to the disconnected state.
