How do use one of these please.....

[sythai]

Evening chaps...

Sorry have searched this but getting late and cant find what I'm looking for (just finished my paperwork - going cross eyed here :rolleyes4::rolleyes4

Seem to be doing a fair bit of fault finding lately - nuisance tripping being a common a one.

So think one of these may be useful for me : earth leakage clamp meter

But just wondering before I buy how do actually use it.... I presume you clamp round the earth core and see what mA it reads - but how would you do this with an appliance ?

Many Thanks,

Sy

This may be of some use to you, (and others) ...if your not sure how to use an earth leakage tester....

Just another questions re : using it ?

Sorry if this sounds a bit blonde ....Can you only pick up earth leakage when you have the circuit energised ? If so how would check circuits that you are unable to energise due to RCD not holding - move them on to an unprotected way if available maybe, but if not ? Thank you.

Well put my order in for one of these... only a cheapy, but should be good enough for what I need

Dilog DL6507 10uA to 60A AC Leakage Clamp meter. Buy online or call

That is a decent bit of test kit, and from what i can see of other more expensive brands, often more than holds it's own and can better some of them too.

Thank you for that.... starting to get my head round it all a bit now, better I think once I actually get to use it.
