look for the resolution. think it's 0.1mA which is fine for tracing earth leakage.

You get what you pay for.
(Drop unknowns on the floor = drift)
( compare with a "Known" situation at home for some stability )
But you could pay for quality - and have it banging about in the van -little used for years !
(With all this DC type RCD/RCBO changes ,I'm still unsure what is around the corner)

I'm a cheap skate .. (but once you look into DC -twiddling with zeros is needed on some)

FLUKE 771 | Fluke 771 Clamp Meter, 100mA dc | RS

uk.rs-online.com

I use one of these. Being able to move the clip separately is handy. Just make sure it pointed in the right direction. I often couple it up with the other one for signal faults, Fluke-709 | Fluke 709 Multi Function Calibrator | RS Components - https://uk.rs-online.com/web/p/multi-function-calibrators/7769529/ . Very handy if you carry out fault finding on your own.

@Haworth
Just in case you didn't realise, David is having a bit of fun with that recommendation. Don't clamp a 771 around an AC line, it... won't appreciate it.

As for AC leakage clamps, I use an AEMC model 565. It has a high range to 100A AC, low range to tens of microamps.

I use one of these; P01120576Z | Chauvin Arnoux MA400D-250 Clamp Meter, Max Current 399.9A ac CAT IV 600 V | RS Components - https://za.rs-online.com/web/p/clamp-meters/7781059/

It's small, CAT IV rated, convenient with a flexible clamp and pretty accurate down in the low miliAmp range as well as up to 400A. Had it a few years and can't find fault with it (pun intended).

My current clamps are :
fluke clamp 1:1000 ratio producing 150A from150mA DMM output
Fluke 360 reading from 1uA to 60A brilliant for tracing fault currents.

Pete,I’m guessing Harmonic hum, or over sensitive RCD tripping
