Abstract
A circuit interrupting device having a reverse wiring protection function is disclosed. The circuit interrupting device includes a housing having a cover and a base, a mounting plate, and an electrical component mounting member, a pair of input hot and neutral conductors and a pair of output hot and neutral conductors, a differential transformer for detecting a leakage current, a disconnecting mechanism for connecting and disconnecting the output conductors to and from input conductors, and a mechanism for preventing reverse wiring, which includes a coil connected to the input hot and neutral conductors and a moveable piece that moves when the coil is energized. The input and output conductors are electrically connected only when the coil is energized by correctly connecting the power wires to the input conductors of the device. This device thus provides both leakage current protection and reverse wiring protection that protects against incorrect wiring during installation.
