Strange RCD Fault

[Guest569]

80amp main switch RCD, occasionally trips when a couple of circuits are switched on (doesn't matter which circuits) with nothing plugged in.

IR tests all good. Replaced RCD for new. Happens in all weather ( don't think its external )

Only sockets on this consumer unit.

Ive had my guys out at it twice with no joy. New build wiring from 16th edition.

Im going to investigate myself this week, Im sure Ive had loose connections causing tripping before, it about all I can think of, a loose tail somewhere around the main switch.


Anything else to look out for ?

Im pretty certain its not a dodgy nail at floorboard etc its fairly new property and in good condition with chipboard throughout.

Thread??

It started as a thread, grew into string, then cord and then developed into rope. Just now it's like a ship's hawser and still growing!

I saw a classic clip on you tube maybe you know where it is Geordie , where Oz decks Big Baz , classic that one ,,,lol

Seems like a big insulation for one RCD even if it just covered half the circuits! Have you thought about RCBO's? Sorry if I'm repeating any one the thread is 13 pages long so I haven't read it all.

Oh yes!!!

That was just a typical Geordie "misunderstanding".

Excellent, 1k is on the table pal....

I can't believe how people are confident in finding this without even seeing the installation! Either very naive or incredibly fast while incredibly superhuman.

Ill stand by this, I could really be doing without this hassle Ive inherited as I have a ton of work kicking off. If any spark wants to solve this ( in one day ) and can provide an invoice. Ill pay 1k...

Takers ?

I can think of quite a few electricians here on this forum (including myself) that could and would be able to find the cause of your tripping RCD problem, and it wouldn't take them a whole day to do so either. No they are not ''superhuman'', and it's not rocket science either, it's just a matter of knowing what they are doing and why. There is nothing out there, that can take the place of experience. That experience combined with methodical intelligent fault finding, will ALWAYS lead to the fault being found, ...or at least to a localised location where access is severely limited!!

For someone that claims to conduct as many rewires and the like as yourself, how the hell have you got by without a leakage clamp in your test kit...

May i suggest this model from our forum sponsor, that has specifications equal too or better than other leakage clamp meters available at much higher costs. You'll also get a 5% discount from our sponsor too!!

So it wasnt the leaf flapping about that was causing the rcd to trip out then???
Thats normally first thing i check is the flapping leaf.
When customer says to me i have a fault the first thing i ask is have you plugged in a flapping leaf lately or got one blowing about in your consumer unit???

JRC this is not a dig but instead of doing the above maybe you should be at the customers with your test gear, you say that you cant devote too much time to this fault due to your busy schedule, but sometimes you have to switch your phone off and deal with the customer and their problem until it is resolved. A business can take years to build but can be destroyed in no time at all / remember you are sometimes only remembered for your last mistake. I get the impression from nearly all your post's that you are trying to do too much to fast, slow down and take care of the customers that you have 1st before you chase after new ones.

I appreciate your advice, People say Im going to fast but in all honesty Im not here to "make a living" from a relatively successful electrical contracting company. Im aiming much much higher. Im not going to get there by taking one customer at a time.

Anyway Ive instructed Mods to close my account. To many threads on here wrongly portrait the OP as incompetent, not just mines. Ill no doubt start another account but certainly not with my company name on it ! lesson learned !

Very wise.

The public display here of your ineptitude, incompetence and pure bullshine cannot be a very good advertisement for your business.

i sincerely hope you're going to stick around long enough tolet us know what the fault is. assuming you find it before xmas.

It will be found long before Easter Tel. He's getting Wor Trev to find and fix it for the modest sum of £1k and as much Broon as he can drink.

No need to worry Tel, Trev is packing is tester in to the van as we speak and will be back on forum by teatime to tell us what it was

Bloody Geordie fast fingers
