Abstract
The present invention is directed to an electrical wiring device that includes an illumination assembly coupled to at least one detection circuit and disposed in the housing portion. The illumination assembly includes at least one light emitting element, an illumination circuit, and at least one lens disposed in at least one lens cover opening in optical communication with at least one light emitting element. The illumination circuit is configured to selectively drive the at least one light emitting element between a deenergized state and a light emitting state in response to an ambient light condition, a miswire condition, an end-of-life condition, a reset state or a trip state. The at least one lens has a surface area such that light emitted by the at least one light emitting element is directed into a spatial volume proximate the electrical wiring device.
