Always always test to make sure circuit is dead

does the stolen neutrals scinario only show up if the other circuit is switched on????? does a neutral to earth prove this aswell???id say i wade in . i was working in a house on friday and my multimeter was showing voltage on a cable but when i isolated still showing 12v or so and couldnt see where the cable was going too and couldnt check as would of ment busting holes in ceiling of an attic, was a nightmare to explain as i bought a light before but then it couldnt go up... i live and learn
...
ps you know anywhere with good offers on approved voltage indicators as i might make purchase today.. then i wouldnt of had my problem

Lads tell me..You come across a wire a single/pair lighting or power.
How do you prove it dead ? No E to the light circuit ? Maybe the E and Neutral are cut off, so you have a Line Live. and nothing to test it against, I know how I do it, I take a proven E from say a proven circuit say a ring and test to that.Don't get fried guys
