and would you do any earth fault loop impedance test to test it

You need to edit your profile as you are neither a general all rounder nor a teacher.

Also, most of the questions you are asking have already been answered on here many times, have a read up and do some research yourself. Feel free to come back with questions about things you are maybe not clear on but it would be handy if you could show that you have bothered to try to find the answers yourself.

That would be highly likely Ginger but I refer you to Lurchio's post above.
