Hi all
I want to get a good and reliable earth leakage clamp meter, been looking at the megger DCM305E which looks good but was wondering what other peoples opinions are? I don’t mind spending the money on a good one rather than getting a cheap one and getting inaccurate readings or no longevity.
Hi all
Suggestions please. I’m working on a 3 phase shop install with a bunch of typical circuits. As each cct is energised the earth leakage rises to around 5 amps! It’s a PME supply via SWA with main earth coming from the armour. I’m pretty sure it’s not the individual ccts or appliances...
Hi all,
There's 2 single fan ovens in the house my mother recently moved into. Posh elecronic AEG units. It's been sat empty for a year, so the oven elements will have had a chance to accumulate some moisture. There's a dual RCD consumer unit, the ovens are on separate RCDs. One of the ovens...
I'm new to this but stuck with an issue, so I'm looking for some help wherever possible. I have just completed a rewire, which I have a potential difference of 60v between MET and disconnected mains earth. It's an RCBO board with type 2 SPD. I have fully tested the installation and have greater...
Hi all,
I can't understand why but I always get a small (minimum 0.06mA) earth leakage reading on extension leads (even without surge protection).
Is this normal?
If it is, please could someone explain how earth leakage occurs on a simple extension lead?
Thanks
I recently borrowed one of these to diagnose an earth leakage problem, and it was very useful: 560 60A Digital Earth Leakage Clamp Meter - https://www.cef.co.uk/catalogue/products/4131796-60a-earth-leakage-clamp-meter
Before I go out and buy one for us, I wondered if anybody can recommend...
Morning,
Customer has a intermittent trip which I am trying to locate. 4 circuits on rcd. Two rings , cooker and hob and one I cannot find actually powers anything as yet. Rings test fine and cooker circuit is okay continuity and I/r. I have put my earth leakage clamp on tails and when I go...
Is there any guides on how much earth leakage is acceptable in an industrial setting ie MCC. The reason i ask is it seems to be most sites have a degree of leakage which I’m not sure is due to many VSDs being used but recently a panel I saw had 0.6amps leakage but the motor starter was all good...
While waiting for a reasonably priced earth leakage clamp meter that will do both AC and DC leakage, I find myself asking the question which is the title of this post.And so tonight (been prompted by "Listers" Post) I thought "why not ask the forum? I have to date never not solved any faults to...
Just thinking out loud. IEL (intentional earth leakage) is already having a significant impact on domestic socket circuit design. It's impact is going to continue to increase as virtually every apiance incorporates electronics. RCBO populated DB, s will become increasing necessary to cope with...
From a brief bit of Internet research my understanding is earth leakage circuit breakers monitor voltage on the CPC rather than an inbalance in current between L &N as an RCD does. Is this correct?

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...
hi all,
If there is such a thing as 'typical' values, what, in your experience would you consider these to be from equipment such as pc's and other IT, washing machines and any other significant sources?
thanks
Hi everyone, I have measured an earth leakage on twin Flo light fittings (2x58W fittings) in open plan office. Office has 18x twin Flo light fittings which are divided into 3 separate circuits, and 3x (10A) RCBOs for each circuit. I have reading of 3mA at each light fitting. 2x circuits are...
Hi all. Im looking for some help regards a massive earth leakage issue in a new i installation
Its a little more complicated than this but its hard to explain. New board 16 way tails splits due to old board still i operation for new few weeks. Large 4 bed house. Pme system. Earth verified...
