Socket Tester Works Load Trips...

Well spotted.

the Blue coming IN from the main house CU should go the the other top terminal of the RCD, and not straight to the neutral bar.

That being the case, this has probably never worked, so dispels my previous theory of the last owner disconnecting it to avoid part P questions at the time of sale.

steps noticed aswell, but posted between me reading it and replying

I , of course , noticed this  IMMEDIATELY :innocent    

Certainly sounds like no neutral through the RCD , just the live  assuming the RCD is the main switch .

If you decide to alter it New Homeowner,  make sure you switch OFF first.

We can talk you through it , but a photo would be best first.

Thanks again everyone - Like I say, I will provide photo(s) when I can...

BUT ... from memory (and it's getting hazy).. The thicker blue cable from the RCD goes from (I think, could be wrong) the Left Hand Side of the RCD into the Neutral bar - This cable is 10mm or more, maybe 16mm?   And the blue from the incoming SWA goes to the neutral bar.  This cable is 4mm, I'd guess, maybe 6mm....   The red from the incoming SWA goes to the top RIGHT hand side of the RCD.  The yellow from the incoming SWA goes to the Earth bar.

The bottom of the RCD has the brass bar in the RHS (Live?) and into the two Circuit Breakers... but the Bottom Left Hand side is empty....

This is from memory now because I'm not at home....

So are you guys saying the thicker cable from the RCD is usually in the bottom left on Wylex RCD's and the top left should have the incoming SWA neutral?  And that the incoming SWA neutral should NOT go into the neutral bar but into the RCD top left slot? - Hmmmmm....

At the main house CCU, the RED is in the top of the 32A Circuit Breaker, the yellow in the Earth bar, the blue in the neutral bar - just like all the other circuit breakers (for lights, ring circuits etc..).  This is definite - but I MAY be forgetting how the RCD is wired up.  I'll check this...

THANKS everyone!

both live & neutral must go through the RCD. since you only have the live through, then the RCD is doing its job in detecting an imbalance and tripping

Yes, that's what we are saying.

Turn off the power at the main house CU first and swap that over and all should be well.

Look at the photo's on the SBS thread and you will see how it should be.

Thanks so much to everyone who took the time to reply to this thread!

do please let us know id that solves the problem.

Far from a perfect example but this is mine in my shed. Its a main switch rather than an RCD but you can see the blue (neutral) and brown (live) wires going into the top of the switch and the blue neutral link out the bottom and to link the neutral bar.

The breakers are then linked to a live bus bar.

Got it.  Thanks Apache!

Apache....forgetting to tell us he had isolated at source before removing cover, silly Vet.

BUT kindly leaving switches in the ON position for carity so that we can .....well, you know the rest

just fuffing about

I'm supposed to put the cover back on? :innocent

I thought this was why I had insulated screwdrivers...........

Obviously WAS isolated.

Apache.....Cow Fiddler!

Nice!

I have some PPe, Arc Flash gear, marigolds, incontinence sheets, leather overgloves, cotten liners etc, should you need them?

they are not for work use , just, a personal pastime

Nooooooooooooooooooooooooooooooo

Leave the covers OFF for ventialtion..

Don't you remember those threads about MCB's overheating & catching fire  ???

Cover off = Cool.

NO overheating etc..

SL - seems wise? Should I put a cone or something in front? Some of that red and white tape?

 

[steptoe]

Im glad that has been sorted,

I shall now print this out and present it to my wife the next time she moans about the cover being off our CU for the past 4 years,

Hello everyone - I'd just like to Thank once again, everyone who has contributed to this post, particularly in the past few days.  The problem as described (and shown by Apache) was EXACTLY the case in the Garage. Moving the incoming SWA neutral to the RCD Neutral in fixed the issue and the Garage now has a fully functional fluro light and radial circuit.

Thanks

Thanks for letting us know.
