  • Patent number: 8369068
    Abstract: A transfer switch enclosure is provided for housing a transfer switch that selectively connects a load to either a utility electrical grid or a stand-by electrical generator. The utility connection includes a first switch selectively connecting utility power to a load. The transfer switch selectively connects the load to either the utility power or a secondary power source. The housing includes a divider panel, providing two separate chambers in the housing. The utility connection is mounted in one of the chambers and the transfer switch is mounted in the other of the chambers. The divider panel includes an opening to permit a pair of electrical conductors to pass therethrough for connecting the utility switch to the transfer switch. The housing further includes two door panels, each door panel covering one of the two chambers. Each door panel is independently operable and securable, controlling access to each of the two chambers.
