Screwdriver Volt/Mains Tester

also, contactless testers (or shock sticks, or dumb sticks, or all the other names we used to call them) should never be relied on to check if something is live.

If you aren't sure, don't.

I won't use a neon test lamp (which is what you are playing with) to test for live, I'll use contactless first, on a known isolated circuit, then if I can't confirm isolation at the main breaker panel (or consumer unit in your house), a test meter. for 20 quid you can get a LAP unit from screwfix that means you aren't the path to ground. (I've got this one https://www.screwfix.com/p/lap-ac-d...MIhbDK0cf-jwMVzaJQBh3NiTQKEAQYASABEgJDQ_D_BwE)

worst case, shut down the entire unit at the main breaker. I've been stung before by believing things I shouldn't, not normally in a home though, normally on a site where LOTO has been completed and someone has fucked up. Hence, ALWAYS TEST WITH THE RIGHT EQUIPMENT.

there you go, an actual HSE comment. :)

now, how does a neon test lamp work?


(I have two of the new version Clive talks about from way back when, still nope).
I believe you may have redeemed yourself...I guess best leave it to the big boys who know what they are doing or let someone else do it and watch from a safe distance? 😀
