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.....
