ARC MANAGEMENT SYSTEM FOR AN ELECTRICAL ENCLOSURE ASSEMBLY

摘要

An arc management system for an electrical enclosure assembly is provided. The electrical enclosure assembly includes a housing assembly and a conductive bus assembly. The arc management system includes a number of conductive bus extension assemblies, a number of first and second arc horn assemblies, and a number of ground conductor assemblies. Each conductive bus extension assembly includes a conductive member coupled to the conductive bus assembly. Each first arc horn assembly includes a conductive arc horn member. Each first arc horn member is in electrical communication with an associated bus extension conductive member. Each second arc horn assembly includes a conductive arc horn member. Each ground conductor assembly includes a ground conductive member. Each second arc horn member in electrical communication with an associated ground conductor assembly ground conductive member. Each first arc horn member is associated with a second arc horn member and disposed an effective distance therefrom.
