Abstract
An AC power line protection device which includes miswiring protection has an indicator lamp which lights when the device is in the tripped condition and turns off when the device is reset. The protection device also includes a protective circuit which protects the AC power line from downstream faults. The indicator lamp and/or the protective circuit are powered via the hot line bus bar by connecting a breaker spring to the hot line bus bar. A contact post is then connected between the breaker spring and an underside of a printed circuit board where power is provided to the indicator lamp and/or the protective circuit.
