Okla been an electrician for 20 years currently work in high voltage switchyards
And that is a clamp on amp meter and is only good for max of 600 volts
A lineman would never use a tool like this other than at home lol
I realize that the power grid is high voltage and low amp.
Like I said that is what the retired Navy electrician called it and he was the head electrician on a ship. He also worked as an electrician at one of the major plants in the area. Maybe it is what the old timers called it or maybe it was his name for it. He passed away about 14 years ago. He taught the City of Stillwater and their engineers that it was possible to run three phase off single phase power before phase convertors were around the area. I assume that was part of the information he aquired in the Navy.
He had one very much like this (two heads) in his vintage tool collection. You can see it was called a Tong Test Meter by the manufacturer at that time.
I found a cool picture of the 5 headed one and it does a 1000 amps on one of the heads.
