Hello, and as they say, "everything is relative". What you labeled as "HV" in your reply is generally considered to be medium voltage (MV) in electric power distribution terminology. The three (sometimes less than
3) wires seen on the cross arms of utility poles (usually up to 34 kV line-to-line) are MV, not HV. The voltage levels for the MV designation have changed over the years depending on what IEEE and or NEMA standard is being referenced but currently in the US the range is from just under 1 kV to 69 kV. It may be "MV" but it can kill you instantly. Sincerely,
