Problems solved by technology

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 negligence during installation and use to form a reverse connection, the panel jack will always be charged, and the leakage protection function will be lost. Like this, often can cause bad consequence, therefore need a kind of function more perfect, more secure ground fault circuit breaker; And the reverse connection protection device of the present invention makes the function of the whole ground fault circuit breaker more perfect, and improves the ground fault circuit breaker. device safety performance

Embodiment Construction

[0026] figure 1 It is the three-dimensional appearance diagram of the GFCI using the reverse wiring protection device of the present invention; wherein 40 is the mounting piece, 31 is the load power jack, 32 is the circular grounding jack, 60 is the reset button, 50 is the test button, 30 is the upper cover, 113 is a grounding screw (green), 110 is a power connection screw, 10 is a base, 111 is a load connection screw, and 114 is an indicator light (light-emitting diode LED).

[0027] This appearance diagram is an appearance diagram of a GFCI with a current of 20A. The reverse wiring protection device of the present invention can also be used on other types of GFCIs, and these types of GFCIs have two structures with indicator lights and without indicator lights. The principles are the same, and here we will mainly explain the GFCI using the reverse wiring protection device of the present invention and a current of 20A with an indicator light, and no other explanation will be g...

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...
