Abstract
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.
