Say the calculated capacitive charging current is 6A (under single phase to ground fault) and you choose to limit the ground fault resistive current by 10A.

What would be the current through NGR under actual single phase to ground fault situation? 6A or 10A?
What would be the current through NGR under Normal conditions?

Most likely it would be 10A.it depends on the added resistance of the fault.

The charging current is the possible current when everything is working correctly. You want your NGR to be able to handle this 6A continuously and not be in alarm all of the time.
