Abstract

An apparatus and method for preventing the miswiring of a protection device. The protection device includes line terminals and load terminals. The protection device further includes a latching mechanism, adapted to move between a closed state which establishes electrical contact between said line and load terminals, and an open state which prevents electrical contact between said line and load terminals; and an initial reset prevention mechanism, adapted to prevent said latching mechanism from being set in said closed state until power is applied to said line terminals.
