An apparatus includes an enclosure, a power switch, an absence of voltage detector controller, and an absence of voltage detector. The power switch is mounted inside the enclosure and configured to switch electrical power from a line-side power line to a load-side power line. The load-side power line is configured to transfer the electrical power outside of the enclosure to an industrial control panel. The absence of voltage detector controller is configured to determine a presence and an absence of each of a plurality of phases of the electric power on the load-side power line inside the enclosure. The absence of voltage detector is visible from external to the enclosure, has a switch, and is configured to illuminate one or more lamps indicating the absence of the electrical power on a corresponding one or more of the plurality of phases in response to a pressing of the switch.

An interlocking external actuator for accessing an electrical panel board having a circuit breaker inside a housing that is covered by an enclosure door, wherein the actuator includes a handle, a first shaft, a second shaft and an interlocking mechanism, wherein the second shaft engages the first shaft in a closed state of the door and thereby facilitates switching the circuit breaker to ON and OFF states by angularly displacing the handle, wherein the interlocking mechanism is biased to engage in pushing the door into a closed state, wherein the circuit breaker is switched from an ON state to an OFF state by displacing the handle from a first angular position to a second angular position, and wherein the interlocking mechanism is disengaged through displacement of the handle further to a third angular position and thereby allow opening of the door.
