Abstract

A reverse connection protection device for providing reverse connection protection for a ground fault circuit breaker, comprising a base, a connection device for carrying electricity and conducting a load, an electromagnetic tripping mechanism and a control circuit. The connection device for electrically conducting the load includes: a first connection device electrically connected to the power supply, a second connection device connected to the load terminal, and a third connection device connected to at least one user-accessible load terminal. The electromagnetic tripping mechanism is operated through the control circuit to drive a frame body to move back and forth. When the release mechanism pulls in, the hook on the frame can be pushed as the first wiring device to connect to the energizing circuit between the second and the third wiring device; The buckle mechanism is in the tripping state, and the ground fault circuit breaker cannot be reset, so that the entire control circuit and the panel jack are not charged, and the ground fault circuit breaker can work normally only when it is installed correctly.

Description

technical field

[0001] The invention relates to a reverse wiring protection device, in particular to a reverse wiring protection device providing reverse wiring protection for a ground fault circuit interrupter (GFCI). Background technique

[0002] Because the ground fault circuit breaker can effectively prevent personal electric shock and ground faults from causing equipment and fire accidents, it is widely used.

[0003] With the development of science and technology, ground fault circuit interrupters are developing towards high performance and multi-function. The previous ground fault circuit interrupters generally do not have the reverse wiring protection function. The GFCI socket can not only connect the load through the jack on the upper cover panel, Because the jack is directly connected to the load terminal. The load can also be connected through the load terminal screws. Therefore, if the input power (Line) is mistakenly connected to the load terminal (Load) due to...
