Neon Mains Testers
15 Answers
Not a question... just a bit of info for anyone who uses one of those things where you put your finger over the end while trusting that they haven't got wet... or failed. There have been several threads recently where neon testers have been mentioned.
Plus the fact that they don't even tell you half the things you really need to know.
This is a kind of entry level mains tester. There are much more expensive professional ones, but this is a good make. Of course, I have to say, other good makes are available.........

Yes, I agree that in an ideal world the Fluke tester recommended should be in every household toolkit. The problem is that the vast majority of the public will not be prepared to pay this amount for a reliable tester. This would especially apply to those that intend to use it for a one-off application. Regretfully, no amount of cajoling would convince them otherwise. Times are hard.
I'm well aware of the shortcomings of mains tester screwdrivers and I'd agree that putting one's confidence in these things is foolhardly. People have been killed in the past using defective main tester screwdrivers.
To my mind, one of the most useful devices for the non-professional householder is one of these or at least something similar:

They are not overly expensive and are readily tested prior to use by simply running them on a wall where a working mains cable is located. If it doesn't bleep, chuck it.
It's considerably cheaper than a Fluke device and within the budget of most householders.

I ended up as an electrical shift charge engineer in the mines and we worked on all voltages up to 11kv and neons were not only discouraged but were actually illegal underground as non certified electrical equipment.This was what we used

There were several types available capable of sensing from about 25v up,not really of use in a domestic situation,though it was ok for finding cable runs in a wall, but it set us a standard and even though I don't do much electrical work these days I always double check I've isolated then then use a multi meter to make sure.better to be safe the sorry.
