Re: Neon Tester Screwdrivers
It's always good to hear the advice of professionals so I had a look at electricalsafetyfirst who seem to require either a two-terminal tester made for the purpose or if that's inconvenient a contactless tester.
I'm personally uncomfortable testing between two points with a probe in each hand, but unless there is a suitable terminal for a croc clip that's what you have to do. Worse, how does that work if say your earth circuit has become live?
As Ian says, contactless testers tend to light up if you touch any metal. It makes better sense to have a contactless tester without a blade and I might be tempted next time I'm in Toolstation. I already have an NCV facility on my Uni-Trend UT210E AC/DC Mini Clamp Meter which works ok, the specs says it will detect mains voltage at 15mm from a conductor
To me, a neon tester is the most trustworthy test if you can get someone else to open the breaker and you see the neon go out
