    EARTH LEAKAGE CLAMP METER

    I am looking at buying an earth leakage clamp meter AMECaL ST-9810 (£59) or a Megger DCM305E (on offer at £194). The only use will be mainly domestic fault finding. Any opinions will be most welcome.

    Good mid range earth leakage clamp meter

    Could anybody reccommend a good earth leakage clamp meter, specifically one that measures low mA's to find any small earth leakage current that may cause nuisance tripping? Megger is my usual go to but don't want to fork out more than around the £100 mark if I'm able to get something pretty...

    Leakage current meter - recommendations?

    I'm looking at buying something for measuring leakage current - The Megger DCM305e (I think). Not specifically for nuisance tripping but more for DC leakage current - type A vs AC RCD (type AC flooding with DC and not tripping). Not a lot of info on the DC side - except DC units for PV, I...

    Find electrician to trace earth leakage

    OK, so this is a follow-on to my thread about unsatisfactory EICR. There is a big inconsistency in that the EICR reports all the L-E IR as >100 Megs, but the inspector also comments about earth leakage in two ring mans and one lighting circuit. This seems to be stopping me from replacing the...

    Leakage meter usage/selection

    Hi. I have a question about earth leakage meter usage/selection. I see that people say one should test the live wires not the earth for reasons you guys probably understand. However earth leakage meters with large Jaws to loop around both tails are much more expensive. Can I use a combination...

    Earth Leakage Clamp Meter...Why do I need one?

    I've read various threads on faults and it's been suggested that an Earth Leakage Clamp Meter is an essential bit of kit and some suggesting it is the first go to bit of kit in fault finding. What am I missing out on then? I do numerous call outs, and have yet to be beaten on one. What's it...

    TN-CS main bonding cable typical leakage current question.

    OK I'm prepared for the usual onslaught so here goes... I recently bought a clamp meter Uni-T UT210E. The first thing I did was check it out against my trusted AVOs and also a couple of other cheapo DMM's, (measure current through wire through probes and compare to clamp reading). The clamp is...
