Abstract
A lighted escutcheon plate for power distribution equipment includes an escutcheon plate in electrical communication with a power distribution circuit; and a plurality of LED bulbs, generally green or alternatively red, mounted on the escutcheon plate, so as to provide a visual indication of an open circuit status by lighting when the power distribution circuit is opened. The plate also includes a plurality of LED bulbs, generally red or alternatively green, mounted on the escutcheon plate, so as to provide a visual indication of a close circuit status by lighting when the power distribution circuit is closed. For tripped circuit conditions the plate includes a plurality of LED bulbs, generally yellow or amber, mounted on the escutcheon plate, so as to provide a visual indication of a trip circuit status by lighting when the power distribution circuit is tripped. Each of the plurality of LED bulbs are electrically connected and mounted such that should any of the plurality of LED bulbs fail, the remaining LED bulbs are capable of lighting to provide the visual indication of corresponding open, close and trip circuit status and the failed LED bulbs are capable of being replaced with…
