I connect a Hypertherm Max200 to 3 phase 415A, 100A MCB on my factory electric panel . But, the earth leakage circuit Breaker (ELCB) trips from time to time.
I suspect the problem may coming from the ELCB. I plan to change the ELCB to a new one with less sensitivity. Any specification of ELCB requirement for MAX200 from Hypertherm ?
the sensitivity range are from30mA, 100mA , 300mA...
