Abstract
An aircraft electrical appliance is provided with a ground-fault-interruption device () for protecting it in the event of problematic current loss due to, for example, a compromise in electrical insulation. The device () has a GFI circuit () comprising a current differential determiner (), a trigger () that is activated upon the current differential corresponding to ground-fault situation, and an interrupter () that interrupts power supply to the appliance upon the trigger () being activated. The GFI circuit () is electrically independent of electrical controller components of the appliance, thereby avoiding expensive software configuration and confirmation.
