2-2 Wiring Choose the sensitivity current of the earth leakage breaker (ELB), depending on the total distance (L) between the Inverter and the power supply, and the Inverter and the motor. Guide of leakage current: If a CV wire is used and routed through a metal pipe, the leakage current is 30 mA/km. Due to the higher specific inductive capacity of the H-IV wire, the leakage current increases about eight times. Use a wire with a sensitivity current one-level higher. The leakage current mentioned here is the effective value of the fundamental wave, and high-frequency currents are excluded.
