    Why does my current clamp meter show large current in gas pipe?

    Went to a house this morning to locate a fault causing the RCD in a split load board to trip. Going through the usual tests, I decided to put my earth leakage clamp meter on the earthing conductor. Here is where it gets weird: with the main switch in the off position, the meter was reading...

    Earth leakage clamp meter

    Hi It’s a bad setup but I went for a call out in the night in a residential unit. There’s a rcd in its own enclosure feeding a 14 way board that had tripped. I reset it didn’t trip. I passed 2 mornings later and still hadn’t tripped. Whilst there on first visit I stuck my earth leakage clamp...

    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

    Current Clamp Question

    I have a Megger MFT1741 with current clamp, also a Fluke 117. As the MFT can't record min/max, I'm using the current clamp with the Fluke multimeter, following Megger's instructions and understanding the 1000:1 step down ratio. Just taking some basic readings on known values, the results are...

    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...

    Anyone know of a multicore clamp meter?

    Evening all I find myself in need of a multicore current meter, much like the old Megger MMC850 (now sadly discontinued) for use at a data centre where I work. Anyone have any ideas at all, I'm stumped! Megger stopped producing the MMC850 some years back (apparently due to lack of sales...
