Bought a new mill machine and it uses a variable frequency drive. I think it’s tripping my earth leakage circuit breaker. Not sure as I was in the garage and wife reset, good job I wasn’t being electrocuted. I have occasionally problem with these tripping out form time to time with other equipment in the house. I have a lot of test equipment and this tends to have a lot of filtering capacitor etc.
The milling machine runs fine and it only trips at power on as again I suspect some large filter capacitor this is the case with other inverter drives I have used. I’m running the machine via an isolation transformer at the moment but it’s not really rated for the load current of the machine.
Anyway can any electrician out there tell me is there anyway to change it the ELCB to something lest sensitive?
I’m going to speak to the machine builder on Monday put suspect they won’t be helpful. I wonder if I should do a past test to check there’s not a real earth fualt but don’t want to damage the variable frequency drive.
Any advice welcomed
Thanks .
