An electrical wiring system providing selectable referencing to earth ground having a housing having a first terminal for attachment to HOT, a second terminal for attachment to LOAD, and a flexible terminal having a first leg mounted to the electrical wiring device and a second leg connected to the first leg via a flexible joint, wherein the relative distance between the first leg and the second leg is adjustable between an extended position and a retracted position by flexing the flexible joint. The flexible joint being biased in the extended position, wherein the first leg defines a first aperture and the second leg defines a second aperture, and a load control circuit disposed within the housing and receiving a line input from the first terminal and a reference input. The reference input being referenced to the electric potential of the flexible terminal.
