Stupid question time...

How does an earth leakage clamp meter differ from a clamp meter (if at all).

Both tend to test IVR so are we just talking sensitivity, resolution and range? When does one become the other (if at all).

a "normal" clamp meter measures amps, a good one will have a range from 20A to 100A, but with a resolution of 0.1A at best. obviously no good for measuring leakage current in the order of mA.
earth leakage camp meters have a much higher resolution but lower range, typically <20A max.. cheap ones 1mA, expensive ones down to microamps.

More or less what I thought then, clears they up nicely ?

yep. think you got it right in OP. my main concern about leakage atm is i got 44 bottles of beer conditioning. don't want any leaks. and i still got that MFT lead if you want it.

I just need to be able to get out to you atm Tel, may not be til I restart college in September (or whenever that will be ?

44 bottles of beer in garage, 44 bottles of beer, you take one out, chug it and shout "wotcha lookin at", 43 bottles of beer in the garage...

when all this corona rubbish has died down, there' a really nic pub roughly half way between us. Cat and Lion. on the A49. you know it?

Can't say I do, Blue Cap, Riverside and White Barn are the only ones I can remember by you ? mainly due to spending at least 1 evening at any given one of them whenever I was on warden duty at Forest Camp ?

Cat and Lion is on the A49. at Stretton traffic lights,

Nice to see that you can get camp meters nowadays, Tel...
