BTW, the entire page seems to have gone away now.
Anyone care to post some quotes? I only have back to 1978 and I don't recall it being acceptable then.
..........
May I suggest that we close the thread now?

Great post. I bet he will remove it soon.
I try to help some of these individuals but the attack me when I do so.
Thanks. That was gone by 1961 (8th edition) and the section just starts with the magneto. Same for the 1981 version (10th ed).From American Electricians' Handbook, Terrell Croft, 1921:
Not sure what type tester he based his design on. I have several neon contact-type testers that I have used for probably 30+ years. The difference is, I never get a "tingle".
I used to work with a guy that would find the un-grounded conductor by touch (120 volt only, as I recall). I always figured he just had real dry skin as he would occasionally have to lick his fingers to get his "meter" to work. Not my idea of a good idea.
Old school, I guess.When I was going to tech school a long time ago, they would have us help the maintaince guy with his duties, he would check a 480 volt bus plug in the machine shop with his finger to see if any of the fuses were blown! One day he shorted out a 480 volt furnace control with a screwdriver to find the breaker, there were 10 people standing there watching him, after he done it, he was the only one left in the room!
What's the CAT rating on those?But you know that is no different from the screw driver neon tester which allows somewhere in the neighborhood of all of 10 to 15 microamps to flow through the body when used.
