1. A protective electrical wiring device, comprising:
a plurality of line terminals including a first line terminal and a second line terminal;
a plurality of load terminals including a first load terminal and a second load terminal, wherein the plurality of line terminals and the plurality of load terminals are configured to be coupled to an AC electrical distribution system;
a pair of contacts including a first contact and a second contact; and
a latch block being configured to move between a first position and a second position, wherein in the first position the latch block permits the first line terminal and the first load terminal to be in contact with the first contact and the second line terminal and second load terminal to be in contact with the second contact without exerting a force on the first line terminal, first load terminal, the second line terminal or second load terminal toward a respective first contact or second contact, wherein, when moving from the first position to the second position, the latch block advances at least one of the first line terminal and the first load terminal away from the first contact by exerting a force on the first line terminal or the first load terminal, and at least one of the second line terminal and the second load terminal away from the second contact by exerting a force on the second line terminal and the second load terminal, wherein the protective electrical wiring device is in a reset state when the latch block is in the first position and in a tripped state when the latch block is in the second position.
