Claim:
1. A test apparatus that is usable with a switchgear cabinet, the switchgear cabinet having an interior and having an access port through which a circuit interruption device is receivable into the interior from an exterior of the switchgear cabinet, the switchgear cabinet having a number of electrical conductors and a shutter assembly that are situated within the interior, the shutter assembly being operable to move the shutter assembly between a deployed state and an undeployed state responsive to the shutter assembly being engaged by the circuit interruption device, the shutter assembly in the deployed state being in a condition covering the number of electrical conductors and resisting the number of electrical conductors from being visually observed through the access port from a location situated at the exterior of the switchgear cabinet, the shutter assembly in the undeployed state being in another condition uncovering the number of electrical conductors, the test apparatus comprising: a frame that comprises at least a first wall having a number of openings formed therein, the frame being movable between a first position disengaged from the shutter assembly and a second position received at least partially in the interior and engaged with the shutter assembly to move the shutter assembly between the deployed state and the undeployed state and to thereby move the shutter assembly between the condition covering the number of electrical conductors and the another condition uncovering the number of electrical conductors, the number of openings in the second position at least partially overlying the number of electrical conductors and permitting the electrical conductors to be visually observed through the number of openings and through the access port from the location situated at the exterior of the switchgear cabinet.
