    Question about clamp meters

    Well, I say that because I don't think there is a problem other than perhaps my meter reading. Then again, it might not be a problem at all. So I had an oil heater that was tripping the RCD. Element was leaking so replaced it. Also did a complete check of all switches, terminal blocks and...

    Clamp meter and earth leakage tester

    How do you use clamp meter? Do you just clamp the line? Or line and neutral? Also been working with a couple of guys that have earth leakage meters and one clamps the line and neutral and the other clamps the earth? Can someone tell me the correct ways? Thanks
