Re: Neon Tester Screwdrivers
Here we use a "Wigger" sort of a solenoid type tester.
I will use a voltmeter, or a plug in unit that shows all wiring is correct by 3 glowing neon bulbs. If one fails to light then there is a wiring problem at the outlet.
Mu old ham buddy was an electrician working for the state. He used to have to find circuits that ran all over and finding the right breaker, in an office full of people prevented him from turning off the mains breaker.
He would just take a light switch and connect a power plug to it, Flipping the switch to "On" would short the hot to the neutral. He'd plug it in and flip the switch. BANG! the breaker would blow. Likely not the safest thing to do, especially if the breaker had fused, but it worked for him. Something I would not want to emulate.
