Abstract
Disclosed is an end-of-life status alarm indication circuit and method for indicating the failure of the primary contacts of a ground fault circuit interruption (GFCI) device to open when a ground fault circuit is detected by the GFCI device. The GFCI device will protect against the situation where the primary contacts of a GFCI device become welded together and will not open when a ground fault circuit is detected by the device. The alarm indication may be either an audible or visual indication.
