Approved Voltage Indicator

[New2Game]

NIC Geezer has told me i need an approved voltage indicator, but i can get one which is elf proving rather than have to buy a proving unit. Can any1 point me in the right direction were to get one?
Why isn't it acceptable to to test on known source to prove instrument working, isolate, then test installation dead?

you have no way of knowing that the supply is 240v. 110, or even 415v..

Where can i get a self proving voltage indicator then?

You can get one with a self check such as the a Stienel Combicheck, though this is more like a lamp test and cable continuity check. For what it is worth as long as you are using an approved voltage indicator (to GS38) proving before and after checking the isolation you will be OK. What did the NIC guy recommend?

My NIC DI assesor was alright with me using the incomming side of the isolator to use as a prooving source. So long as you are using a voltage meter rather that an indicator (neon screwdriver) you should be OK.

Just prove it works, then test for dead, then prove it still works.

Don't know if it's different for full approved though

NIC Bloke reconds that proving on known live source is not good enough, a proving unit or self proving indicator is needed! Bit over the top if you ask me

I have always been taught never to use a meter to test isolations as they can be misread, set incorrectly etc. I have been taught since I started my apprenticship many many moons ago to always use an approved voltage indicator (GS38). This is by no stretch of the imagination a neon screwdriver!!

But does any1 know of a self proving voltage indicator? NIC geezer said 'style' make one where you put probes together and they go thro self check. Has any1 heard of it, cos i cant find it on net?

Stienel or Steinel??

I can't see why you can't prove it on another circuit, or if worst comes to the worst, on your IR tester!

He is talking out of his bottom. You should always prove isolation, but any source will do and the incoming side of the main isolator is by far the most convenient source most of the time.

I've got this http://isswww.co.uk/productdetail.aspx?id=3595 and my NIC assesor didn't say a thing...didn't pay that much though!!

Are those the test probes that trip RCDs when testing voltage between live and earth?

 

[nozspark]

Yeh, you have to do a test between phase and neutral then do the phase & earth within 5 secs....
