Identifying live cables

[markthebuilder]

If you read my post Charlie I never sugesred I would,In fact I never mentions isolation . I simply asked if there was a better tool for identifying wether a cable is live. Specifically big ones when your only access is to the model of it and it’s source and end can’t be determined ....

Bright idea , a light bulb with a spike ,on a neutral wander lead ,may do it ... but the approved tool will be more pricey ... Do verify its still working every so often !
(Yep you are likely to go BANG if you don't know -nor have a plan)

Ahh sorry my mistake, when somebody talks about cutting through cables I automatically think ‘safe isolation’..
Apologies for my assumptions..

Ok, from what I’ve heard, try these ‘volt pens’
Megger
Fluke
Kewtech - guy on YouTube uses them so must be really good

Please give us some feedback after your meeting with the dno guy, I’m really interested to hear more about this

I have decided the OP is either on a wind up or as thick as mince and stubborn as mud. Best left to it in both cases.

1) I will need a team of sparks befor I’m finishe 2) no I don’t, I have always proved cables at one end or the other or been able to isolate the whole supply. This building is prity vast so when I am sticking my head in places I don’t rally want to go back to and I see a big black cables 2 inch thick I would like a quick way of determining if it’s deep live then I can mark it on the plans. If a volt pen will do volt pen will do it then that will do.. any cables I don’t get a positive result for can get marked up as require further investigation.
However if there is something a bit more reliable than a volt pen I will get one,

There is its called an electrician

....all that said I’m still getting myself a volt pen to make one final check on any cable before I let anyone start cutting with a sthil

Any electrician will ignore your checks (with the volt pen) and check all cables themselves but go ahead and do your checks, it's only a waste of your time and not theirs.

Probably because it wasn’t all checked first with a volt pen

I'm sure the OP can afford an 80 grand fine, so hes ok to tell the electrician he's checked the cable with his volt pen and its dead..
