Abstract

Un dispositivo de interrupción de circuito que tiene un circuito de auto-monitoreo para probar periódicamente varias funciones y estructuras del dispositivo. El circuito de auto-monitoreo inicia una rutina de auto-monitoreo que, entre otras cosas, genera una condición de falla de auto-prueba y determina si los mecanismos de detección dentro del dispositivo detectan de manera apropiada la falla de auto-prueba. Un circuito de falla de prueba está configurado para generar uno o más pulsos de prueba que causan la condición de falla de auto-prueba y los pulsos de prueba son generados para ocurrir fuera de una región activa del circuito de detección de falla.
