This is electrical probulum

Welcome to this forum and good morning.

Yes a line to ground fault is a severe electrical problem.

But beyond that, without more information regarding the failure I cannot help you.

Please let us know, what is connected to this circuit. What the amperage of the circuit is. Did this circuit ever work properly or is it a new installation?

Appears to be a test question. Perhaps Tirth can elaborate.

Apparently we are failing that test so far. Any more info to share with us tirth?

This fault made in electric distribution line.

Tirth, if this is the best you can do, we cannot help.

If you expect a reasonable answer, you have the responsibility of telling us exactly what your situation is, what problem your having, and what is it you need to know.

We are not mind readers.
