CABLE FOR SIMULTANEOUSLY DETERMINING CURRENT AND SHORT CIRCUIT, AND DISPLAY MEMBER FOR CABLE TRAY

摘要

The present invention relates to a cable tray, in which a plurality of electric wires connected to a power source unit for supplying electricity is securely provided therein, comprising: a first electric wire unit for receiving current from the power source unit; a second electric wire unit for receiving current from the power source unit; a coil unit which receives current from the power source unit and is wound around the outer circumference of the first electric wire unit to generate a magnetic field; a current checking unit which is connected to the first electric wire unit and includes iron powder therein; a short circuit checking unit which is connected to the second electric wire unit and reacts to a flow of electricity; and a display member formed at one side of the cable tray. Accordingly, since a user can confirm whether current is flowing accurately through the electric wires accommodated in the cable tray, current flowing in electric devices connected to the electric wires can be assessed. In addition, accidental injuries can be avoided when doing repair work on the cable tray.
