ABSTRACT:
The present invention is directed to an electrical wiring protection device for use in an electric circuit. The device includes a plurality of line terminals configured to be coupled to the electric circuit, and a plurality of load terminals configured to be coupled to an electric load. A housing assembly includes a front cover, a separator, and a body member arranged to form an interior isolation volume within the housing assembly. The plurality of line terminals and the plurality of load terminals are accessible from an exterior portion of the housing assembly. A protection circuit is disposed in the housing assembly and coupled to the plurality of line terminals or the plurality of load terminals. The protection circuit is configured to respond to a predetermined condition in the electric circuit or the electrical wiring protection device. A voltage transient suppression circuit is coupled to the plurality of line terminals, the voltage transient suppression circuit including a spark gap structure substantially disposed within the interior isolation volume.
