Re: Dumb question but I'm serious

It's been over a year now that Mike Holt newsletter sent out an article that came from the Electrical Inspectors Convention,in Las Vagas, that upon testing these 'little yellow' testers ,it was found that badly miswired recpts. would register normal!! I don't remember the exact arangement now,but at the time I tried it and sure enough they wern't lying.

By George:

When the tester tells you hot-ground reverse, it's an open neutral. :)

Well George, if you have one like the one I have that doesn't work it would have to have a bad light, like Steve said, to do that. That would be the red one.

:D

I don't know if there's actually a tester that's built that way because there's a few different ways it can be done. But that circuit wouldn't do what George is saying either.
 
Re: Dumb question but I'm serious

Look at the top schematic. If there is a load connected to the line elsewhere, then the power flowing through that load is seeking a neutral. If the neutral is open, then the only path to neutral for that spent energy is through the red light on the tester, to ground. :D

Good picture, Sam. :D

Edit: Like this:
:D

Re: Dumb question but I'm serious

George. there are less complicated ways of fooling these things than crawling under a building, snipping the neutral, and connecting it to the hot through a resister. :D

How many ways can anyone think of to get this thing to believe that you have a perfect, up to date, current code, receptacle with only two wires to it?

I recommend the beepy thing that makes a bunch of noise at more than 50 volts. Now that's a professional's tool. :D
 
Re: Dumb question but I'm serious

I can't even begin to count the number of old rental units that I've been in where the former owner or maintenance man ran a jumper from the neutral to the ground screw when installing grounded recs. When rental units receive annual inspections in my area, the inspector uses a yellow tester to prove out the recs. That little jumper fools 'em every time.

That's exactly what stands out the most to me. Not to say that they don't work good 97% of the time, when there's nothing to find. :D

Edit: Well that's not fair either. They do fine within their limitations like anything else.
