Lighting in my shed trips the sockets.

[cheesybeanz]

I have recently had electricity installed in my shed with a small garage consumer unit (32a & 6a). The sockets are fine and the electrician informed me if I wanted lighting, I was to install it to the 6a breaker which I have done. I have connected everything up but when I turn the breaker on, the whole sockets trip in the house. See pics below

This is the consumer unit. The white cable in the top right is the lighting cable. This is normal 3 core flex with all ends going to correct parts of the unit.



This is my light. Everything is fine here.


This is where I have connected the Neutral and Earth from the light to the main cable.


This is the switch.



I think i have done everything correct which leaves me with the feeling the 3 core flex isn't big enough. Any help is massively appreciated. Obviously, my connector blocks will be insulated when i've finished.

looking at all those bare strands of copper, amongst other things, all i can say is get your electrician back to fix it.

Ditto.

The project isn't finished yet. The bits of copper will be tidied up when i'm done. What are the other things?

You say your sockets trip in the house.
Is it the RCD in the house that trips or the MCB?
Is this shed supplied from the RCD protected side of the Consumer Unit?

How are you planning on insulating your connection blocks?

 

[telectrix]

sounds like it, and sounds as though he's got 2 RCDs in series. perhaps a different spark to the one who installed it is advisable.

You have attempted to wire your lights and although the cables seem to go to the right places, you need to go to every termination and reconnect them properly. Even a bad sparky wouldn't have left badly terminated cables like these.

Now let's not jump to conclusions Tel! :smilielol5:

OP, can you post some pics of the house CU?

 

[telectrix]

but it looks as if he's used black for N on the incomer, which , itself looks like 2.5mm.

christ. these threads get worse! get an electrician in to sort your lights. should be a nice simple job and won't cost the earth.
question though why would the electrician you got to fit the garage cu tell you to fit the lighting yourself? surely he would do that?!

how many socket outlets do you have in this shed?

 

[telectrix]

old proverb that springs to mind... "penny wise, pound foolish".

 

[cheesybeanz]

The electrician installed the power in the shed it from an existing socket in the kitchen then put the consumer unit at the end of the armoured cable. From the 32a breaker he has put in two double sockets that work fine. It's just the lighting that seems to be the big problem from the 6a breaker.

From what you lot are saying, seems I used a cowboy.

The connection bloacks will be insulated but a chocbox.

Is that connector block just pushed out of sight, not in an enclosure at all??

Edit: Just re-read the OP. Are you planning on just taping that connector block up?

And all the terminations you've done are shocking.

again:
how many socket outlets are of that 32B...

as its a single 2.5/1.5 fed from it...it aint a ring isn`t that...
