New Wiring/Sockets/Switches Keeps Tripping :( Help Please

[davelx]

The SUPPLY NEUTRAL must go into the N terminal at the top of the RCD, NOT into the Neutral bar. The way it is currently wired, the neutral current is bypassing the RCD, which will trip as it only has current on the live side.

Wired correctly, the current through both live and neutral conductors from the supply goes through the RCD which thus sees the same current in both directions and does not trip.

There is far too much copper on show there.

don't understand the annotations on the picture.

What you've done is wrong and will not work. I suggest you get an electrician to do the work properly.

agreed

While the electrician is there he can fit a grommet in the top of the metal (dont know why) CU and try and sort the lack of IP rating

And the 16amp ring too.

Oh dear god, this is exactly why people who dont know what they are doing should just leave well alone. Apologies to the OP for being blunt but please isolate the supply and call back the electrician who installed the original electrics to sort this mess out before you burn your house down.

I can do it but according to the diagram it looks just as I have done. However with abit of help from you knowledgeable guys I can do this plus you electricians cost the earth

I'm only having problems with the consumer unit nothing else, everything else is wired correctly so if I can wire the consumer unit properly job done. I also said previously that it was messy in there and it would be tidy once it's sorted. That consumer unit didn't come with a grommit so I have purchased a pack from Wickes which I will put in place tomorrow.

I will get an electrician in if need be, I just wanted to try myself first. Surely some of you guys have tried doing things first before calling professionals in...? I'm a bricky and chippy by trade so know a few mates but they never seem to have the damn time

Anyway tomorrow I will tidy up the cables and re-wire it accordingly and if I fail I'll call one of you guys promise

Ask any electrician to build a wall and they'll make a right mess of it... but at least it's not going to set their house on fire or electrocute them.

Because I know how to wire up a ring circuit and light loop thats why, my problem is the consumer unit if you read earlier posts I made. I've wired up plenty of sockets and lights in my 40+ years on this planet but I undestand where your coming from. I will get someone qualified to take a look.

Thanks for your help.

Obviously not, or you wouldn't have done it.

Th sockets and lights/switch are installed as should be but the C/U is what I'm having problems with. Anyway after listening to you guys I am going to phone the sparky who did the electrics in the first place. Didn't realise that wiring the C/U was so difficult.

Anway guys thank you so much for all your help and I can assure you that I will be on the phone first thing in the morning. One good thing is atleast all the cables are in place with regards to sockets and lights so it's just a case of the C/U being installed. I read a few threads and what I read made alot of sense. It's dangerous stuff and only a pro will do

Again thanks for all the replies, appreciated

It's not, it's very straightforward if you understand how the components work and why they are needed

I can clear see the 'problem'.

The cable supply that you cut in to !!!

Browns go to live side of rcd (top LHS marked L)

Blues go to the neutral side of the rcd (top RHS- Not marked)

The circuit ends of the cables for ring, lights etc.

Blues to the RHS bar with the rcd blue neutral.

Browns to the relevant mcb

Earths to the LHS bar.

At the moment you have no supply neutral going through the rcd

Thanks guys for your help, however I called out the electrician and he said I wired all sockets and lights correctly, the consumer unit was wrong and as soon as he did what the last post said it worked, also he changed the 16 amp fuse for a 32 amp fuse. Reason is I worked out the watts of the tools I'll be using and machinery and 16 amps asn't enough so decided to up the ampage.

Job done and again thank you for your advice.
