Enclosure for holding an electrical device with dual access panels for safely limiting access to the device while allowing maintenance thereof. The housing defines an access opening with a limited accessing construction thereover. Interior and exterior panels are included each movable to be closed and opened. The interior panel is preferably transparent to facilitate viewing therethrough. The exterior panel is preferably metal and is hinged to the housing for movement between closed and opened positions. Individual accessing apertures can be defined in the interior and exterior panels to allow localized access by servicing personnel. Specific positioning of the access opening in the interior and/or exterior panels provides access to limited areas of the electrical device within the housing and prevents access to other areas for safety. The interior panel can have indicia imprinted thereon to facilitate servicing.

Enclosure means for holding an electrical device having a limited accessing construction with dual panels for safety

This disclosure describes examples of an apparatus to enclose components of a switching assembly of an automatic transfer switch. In one embodiment, the apparatus, or arc chamber cover, has a housing made of material with optical properties that permit observation of the interior of the housing. A mounting assembly couples to the housing. The mounting assembly secures the apparatus to the automatic transfer switch. In one example, the mounting assembly comprises feet comprising a material with mechanical properties that can withstand pressure and other forces inside of the interior chamber. The apparatus also includes one or more baffles to control the flow of gasses and control electric arcs within the switching assembly.
