DISPLAY DEVICE JUDGING AN ELECTRIC CURRENT AND AN ELECTRIC CURRENT LEAKAGE FOR CABLE AND CABLE TRAY

摘要

PURPOSE: A cable simultaneously determining current and leakage, and a display member for a cable tray are provided to easily perceive current flow by including a current confirmation unit. CONSTITUTION: A first cable unit receives current from a power supply unit. A second cable unit receives current from the power supply unit. A coil unit(300) generates a magnetic field in the circumference of the first cable unit. A current confirmation unit(410) is connected to the first cable unit. A leakage confirmation unit(420) is connected to the second cable unit.
