A look at three phase prospective fault current measurement and Ze.
Note: check earlier comments, nylon top hat washers/spacers in place on switch fuse. Its not bushed through with continuity on the metal work. Should have made clear (did in 1st take but camera was on a tripod and I got in the way, my bad!)
Will show in next video to prove this isnt BS. Very good spot by a couple of people so far! Thanks for paying attention and watching, I really appreciate it!
Note: Never disconnect any Earths without first isolating the Installation.
Using the TIS mft pro and GS38 leads.
L L measurement and calculated.
