Earth Leakage Clamp Meter - Great Tool!

Foffer
Maybe I'm behind the times and you've all known about these for years!


I've just started using a Megger DCM305E clamp meter which can measure current from 0.001mA to 100A, meaning that its prime application is measuring earth leakage.  Clamping around both meter tails together or around the cores of a specially made extension lead test rig quickly helps track down the offending item causing RCD/RCBO tripping.  This tool speeds up fault finding a great deal and causes minimum disruption in a working environment.


Just wanted to bring this tool to the attention of anyone who like me hadn't heard of it before!


Also, I don't know if there are similar tools made by other manufacturers.....

    Thanks for that info foffer.

    It`s horses courses.

    Quick check Screwfix seem one of the cheapest fot that model, great price variation from different suppliers.

    I have a couple of cheaper clamps one of which is lowish res and helpfull in earth leak situations to a degree and as said a few winds on a coil helps boost the res too.

    I don`t use often enough to justify price of the one you mention.

    If I spend a fiver on something and it does not save me a fiver it is wasted, if I spend a grand on something and it saves me a grand plus a fiver then it`s an investment.
