Comprising 420, it is composed of a display member 400 formed on one side of the cable tray.

Therefore, when the current supplied from the power supply unit 30 passes through the current checking unit 410 on the wire, a magnetic field is generated by the coil unit 300, and iron powder reacts thereto, and the covering of the wires is peeled off, causing a short circuit. As a result of the flow of electricity to the earth leakage check unit 420 will react with iron powder.

Hereinafter, each configuration will be described in detail.

The first wire unit 100 according to the present invention receives a current from the power supply unit 30 by a wire connected to the power supply unit 30, and is connected to the current checking unit 410 of the display member 400.

The second wire unit 200 according to the present invention receives a current from the power supply unit 30 by a wire connected to the power supply unit 30, and is connected to the earth leakage check unit 420 of the display member 400.

The coil unit 300 according to the present invention receives a current from the power supply unit 30 and is wound to generate a magnetic field on the outer circumference of the first wire unit 100.

Since the magnetic field is generated in the same direction as that of the current of the first wire part 100 according to the law of Fleming, the magnetic field is generated by the current checking unit 410 through which the first wire part 100 passes.

Accordingly, when a current flows in the coil part 300, a magnetic field is formed, and the iron powder formed in the current checking part 410 reacts, so that the current flows in the first wire part 100. have.

* The display member 400 according to the present invention is connected to the first wire unit 100 and the current check unit 410 having iron powder therein and the second wire unit 200 is connected to the electrical It is formed on one side of the cable tray made of a leakage check unit 420 in response to the flow.

The display member 400 is formed outside the cable tray, which is easily seen from the outside.

The display member 400 is divided into a current checking unit 410 for determining the flow of current, and a leakage checking unit 420 for determining a short circuit, such as a short circuit, in the cable tray.

Usually, when observed from the outside of the cable tray, it is possible to determine whether the current flows correctly through the current checking unit 410, and if a short circuit situation such as a short circuit occurs, it may be confirmed through the short circuit checking unit 420, The current checking unit 410 may be arranged to be more prominent.

In the present invention, the current confirmation unit 410 forms iron powder therein, a magnetic field is generated when the current flows to determine the presence or absence of current as the iron powder reacts, the earth leakage check unit 420 is You can check whether there is a short circuit by installing an LED light or a bell that operates when electricity flows.

Here, the ground fault check unit 420 is peeled off the coating of the wires located on the cable tray, the short circuit should be short-circuited, it is normal that the ground fault check unit 420 is not operated.

Preferably, the display member 400 includes a coupling part 430 having a bracket to be coupled to the cable tray, a current checking part 410 formed at one side of the coupling part 430, and the coupling part. (430) It may be made of a leakage check unit 420 formed on the other side or the other side of the current confirmation unit 410.

The coupling part 430 is a bracket for installing in the cable tray, and is detachably configured to be installed anywhere in the longitudinal direction of the cable tray.

The current checking unit 410 is formed on one side of the coupling unit 430, so as to be installed in a direction that can be easily observed from the outside as described above.
