For a test procedure, that is Flat Out Gnarley! I’ve always felt that meters and test lamps were a waste of time. ;-) ;-) ;-) Finally…proof positive.

One question though — What size resistor should one use to scale this up to “110, 220 and 440” volt circuits? ;-) ;-) ;-)

Joe,
Regarding the "American Electricians Handbook" I don't have a later edition but I do have earlier editions. That text was in all pervious edition right back to the first edition (CIRCA 1913 or so), I'm not at home in my library right now. I wondered if it was in any 1950's editions. Like you I wonder how long it appeared. The previous paragraph (not shown) talks about testing for the presence ov voltage with the fingers and suggests that only "real electricians" can handle it. I'll bet that's responsible for the mind set and the "old timers" teaching the newbies that it's OK to bare hand 120v circuits.
Personally I try to avoid mentioning those references for fear of prepetuating that nonsense. Thanks Joe for the historic blast from the past and have a great day.

How about a 2.5 M Ohm (Mega Ohm) Pot, so only one ballasting device is needed acrossed a wide range? Calibration done via worst enemy test subject (Saddam Insane would be qualified test subject).
To increase the "Russian Roulette Effect", use an Audio taper Pot.

Sorry, just couldn't resist this one!!!

That's how I learned to check 9-volt batteries...

Don't think I would like to try that one, these days, with induced voltages in cables.
I like my tongue, it helps me to talk.

Reading this thread, I keep seeing the image of "Uncle Fester" (Adams Family) with the light bulb in his mouth...

I worked many years ago with an old timer who would first lick, then press his thumb against a lug in a panel. He'd then show me the dent in his thumb left by the pressure against the corner of the lug, and say, "Yeah, that's 480 -- you can feel it!"
Good old Rocco, the human wiggy...

That paragraph is also a reason for us to be concerned about thos who ignore the hazards involved when making contact with live terminals.

I just checked my 1970 edition and that information was not to be found, so we need to find out when the words were removed.

It's my guess that it was when John Watt became the editor??

Scott35--it's probably not audio taper, but...
