ABSTRACT:
An arrangement is provided for use in an electrical utility meter that includes a metering unit, a service disconnect circuit, and a housing assembly. The service disconnect circuit has a connected state that operably couples utility power lines to a load, and a disconnected state and as armed state that operably decouples the utility power lines from the load. The housing assembly is disposed over the metering unit and the service disconnect circuit, and has at least one electronic indicator visible to an outside of the housing assembly. The electronic indicator is operable to provide a visual signal representative of the service disconnect circuit in the armed state. The housing further includes an externally accessible actuator operably connected to the service disconnect circuit to change the service disconnect switch from the armed state to the connected state.
