A protection system for an electrical apparatus is disclosed. The protection system includes a baffle assembly and a coating for electrical elements exposed to arc gases. The baffle assembly includes a number of generally planar sidewalls, each sidewall including a first edge surface, a second edge surface, and a third edge surface. The sidewalls are disposed in a spaced, generally parallel configuration defining a number of channels. A first end wall is sealingly coupled to each sidewall first edge. A second end wall is sealingly coupled to each sidewall second edge. A third end wall is sealingly coupled to each sidewall third edge. The terminals of an electrical apparatus are disposed in an aligned set with one set of terminals in each channel. The channels are structured to limit the flow of arc gases across adjacent sets of terminals.

An electrical apparatus housing having a door for accessing the apparatus within the interior of the housing and a switch for activating the apparatus accessible from the exterior of the housing. When in the on position, the switch is operable to block the door from being opened; thus functioning as an interlock to prevent access to the interior of the housing when the apparatus is activated. The invention includes a key for bypassing the interlock so that under certain circumstances the housing door can be opened while the equipment is operating, so it can be tested in its energized state.
