Patent ID: 7265956

Claim:
A circuit interrupting device comprises: a housing; a circuit board located within said housing; a tripping device capable of tripping said circuit interrupting device to cause electrical discontinuity between a line side connection, a load side connection, and a user accessible load when a fault occurs; a reset button; and a dual-function test button having a first pole and a second pole underneath said dual-function test button; wherein when said circuit interrupting device is properly wired and/or powered, a first-level depression of said dual-function test button allows said first pole to operatively connect to a conductive pin which generates a leakage current to test whether components of said circuit interrupting device are working properly; wherein when said components of said circuit interrupting device are working properly, said reset button is capable of being reset; wherein when one or more of said components of said circuit interrupting device are not working properly, said reset button cannot be reset; wherein when said circuit interrupting device is not properly wired or powered, said first-level depression of said dual-function test button does not generate said leakage current, but a second-level depression of said dual-function test button allows said second pole to mechanically trip said circuit interrupting device.
