Abstract: An enclosure, such as, for example, a motor control center (MCC) used in an industrial automation environment, designed to provide pressure relief and ingress protection. The enclosure includes an opening, an optional gasket disposed over the opening, and a pressure relief plate disposed over the gasket including tabs that secure the pressure relief plate to the enclosure. The tabs are adapted to fracture upon a change in pressure within the enclosure to allow the pressure relief plate to open, and thereby to allow pressure to escape from the enclosure responsive to the change in pressure within the enclosure.

Abstract: A system for isolating a power conductor includes a power conductor that extends between first and second flanking support structures. First and second collars are connected respectively to the first and second flanking support structures. The first and second collars each at least partially surround the power conductor and including respective first and second open tracks that cooperate with each other to define a sheet-receiving slot. An electrically insulating/insulative sheet is located in the sheet-receiving slot and extends continuously between the first and second collars. The sheet is secured in covering relation with the power conductor.

Abstract: An improved electrical system may be provided by electrically isolating horizontal power distribution bus bars of differing phases, disposed along a preconfigured isolated bus support molding, from one another by covering each bus bar with an electrically insulating molded assembly. The electrically insulating molded assembly has contours configured to cover a particular bus bar (with respect to another bus bar or live fastener), arranged within the constraints of the preconfigured isolated bus support molding in the electrical system (such as along the back of the isolated bus support, between the isolated bus support and a wall of the electrical system).

Abstract: An improved electrical system may be provided by electrically isolating complex bus geometries by using one or more substantially flat and electrically insulating sheets. The sheet may have one or more fold lines which allow the sheet to fold in multiple directions and ways over varying configurations of power conductors. The sheet may fit within the constraints of preconfigured electrical system components without the need for redesigning such components. The sheet may have a dielectric strength per mil effective to isolate power conductors based on maximum charge and proximity of the power conductors.
