Default Re: Neon Tester Screwdrivers

Use a suitable tester ? And then again ,are the leads in date/safe to use. A non screwdriver ( kept in top condition, chuck it id you doubt it's safety) is something I'd sooner trust. As with all go/no go tests, it's safety essential that the equipment is trusted. Why not test the suspect circuit in the on condition. Screwdriver indicates - switch off and test again. Scrwdriver does not indicate- find a known working circuit and test it. I far these days that the Elf ( as in Elf & safety) has addled folks brains and stopped folks thinking about how to be safe ,unless ther's a long list of safety regulations.
And yes- I was qualified and certified in my last employment to work on 650v circuits, although in my GPO/PO carer, I often workd with 1000v AC power feed on CEL and inside ( certified dead) up to 4.5KV submarine power feed terminals.
