Abstract
A ground fault interrupter is rendered less sensitive to electrical noise by a densensitizing subcircuit. During the time the current to the load is interrupted a control chip is neither fully off nor fully on but is only slightly powered, that is it is desensitized. An LED indication is provided during the existance of a fault.
