ABSTRACT:
The present invention is directed to a modular shutter assembly for use within various types of electrical wiring devices having differing amperage ratings. The modular shutter assembly includes a first shutter member having a first blade engagement structure. The first shutter member is configured to be disposed within an interior portion of the cover assembly and disposed between a set of receptacle openings and a set of receptacle contacts. A second shutter member includes a second blade engagement structure and is slidably disposed within the first shutter member. An interface is configured to connect a third shutter member to the modular shutter assembly and drive the third shutter into an open position only when the first shutter member and the second shutter member are simultaneously engaged by a set of plug blades.
