1.2.4 Selection of Leak Current Breaker
• A ground fault circuit interrupter needs to be selected carefully considering the purposes of
prevention of fire and protection of human.
• Leak current varies depending on the capacity of connected motor, cable length and the
surrounding environment. Measure the leak current at the point where a ground fault circuit
interrupter is to be installed when leakage protection is conducted.
• Use the harmonic type (for inverter) for the ground fault circuit interrupter.
