Visual indication of fault status, storage and clearance in an arc fault circuit interrupter (AFCI) |
摘要 |
An arc fault detector includes a means for repeatedly measuring an elapsed time. The arc fault detector also includes at least one means to perform arc detection at each repeated elapsed time. Means for initiating a tripping mechanism is activated after the elapsed time. When a fault occurs, means for generating at least one fault code is activated. The fault code is stored in at least one non-volatile memory. The fault code is selected from a group consisting of an arc fault interrupt code, a ground fault interrupt code, and a push-to-test interrupt code. The arc fault detector includes at least one means to display the fault code such as at least one LED. At least a first LED indicates an arc fault interrupt code and at least a second LED indicates a ground fault interrupt code. At least a third LED indicates a push-to-test interrupt code. |
