I don't need no stinkin' meter. .
One of the plant electricians I worked with 40 years ago would tap a live wire between his pinky and thumb, then depending how high his hand jumped tell you if it was 120, 208, or 277/480 volts. DO NOT DO THIS!!!
My grandpa had extremely dry skin. He would work on his electric fence barehanded.
He said he just felt a little tingle. Anyone else was knocked on their butt if they just touched it.
He worked on 120v live, too. The outlet in the barn (8 feet from the hay storage area) had no fuse. The only way to kill the power was cut the wire or pull the meter.
