I'm facing an electrical issue in my house since last Christmas. When the lights or appliance with motor in any room are turned off/on the TV would go out and come back on in a short span (as if the power went out and came back in a second). I recently had some mishaps where my two older PCs PSU...
I know every computer/equipment type will have a slighty different earth leakage stated by the manufacturer, however I was wondering what people use as a "rule of thumb" value when designing ring final circuits in offices intended to be used for computers.
I was thinking 1.5mA per computer inc...
Hi Guys, Have a problem with a Omron Switch mode power supply & Omron Control Relay Which is only switching a 3phase mixer paddle to stir liquid while in the heating process. The control gear is fed from a single phase supply plugged into a RCD protected socket. The Rcd trips within 9ms @ X1.

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
Hi My name is Allen Brauteseth from Cape Town South Africa. I am a Qualified electrician and am sitting with a problem being I have a commercial fridge for cold drinks that trips out the earth leakage after running for 10 minutes please could someone help me as the supplier says there isn't...
Hello Everyone,
I am from India. Things were good [seemed to be good] with temporary electric connection [single phase, 230v] to our new house. Now when we are organizing electrical wiring, dividing phases, installing ELCB, the problem started occuring.
Now the electricity connection is of 3...
got a new toy ha ha clamped my new earth leakage clamp around my earth cable local to consumer and was getting 5mili amp leakage question what mainly causes the earth leakage other than computers fridges etc
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.
Hi All,
I had a nuisance rcd tripping fault at a job , I bought a Megger DCM305E earth leakage clamp, which identified the suspect circuit which I swapped out with an RCBO and problem solved!
Ive come home and checked my L-N incomings just to see and I’m showing a 513MA leakage? My board...
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 got one they recommend.
Looking to spend upto £120.
Would like micro Amp resolution if possible single digit milli Amp a must.
Ta muchly.
Edit: only looking at testing appliances and 240V circuits.
(did a search but no conclusive answers found)
I have a customer who has been providing all the accessories for their renovation a real mix of manufacturers and styles, we arrived to second fix and swap existing faceplates to find that every single socket both single and double had usb ports. My question is will these USB ports all...
Alright lads, new here as looking for some advice on a fault I've never come across and can't pinpoint..
Basically Got LED LIGHTS on compatible dimmers etc...problem I have is now and again they flicker....and I can hear a sound in fuse board as if there's an arc? But there are no loose...
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...
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...
I have an odd situation in that I get random earth leakage trips which happen occasionally when I turn off an outside light. I have a standard split board, half earth leakage protected, half not. Trips happen maybe once every 50 times that outside light is switched off, never when it is...
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...
