US Patent 7391597 Switchgear with arc-resistant features

An arrangement capable of being assembled with either an existing installed electrical equipment enclosure having an access door or during the fabrication and assembly of such an electrical equipment enclosure that increases the arc-resistant capabilities and characteristics of the electrical equipment enclosure. The arc-resistant capabilities of the electrical equipment enclosure are increased via the provision of shielding facilities disposed in the vicinity of the access opening of the enclosure to substantially limit the heat generated by internal arcing within the enclosure from reaching the access door to the enclosure.
