Need help pretty quick with eletric box

[tellytv]

Hi,
I replaced some kitchen spotlights, however when I turned the eletric back on none of the lights work at all now? I heard something trip, so I pushed the small grey lever back up however still now working?

Thanks

Have you tried pressing the yellow test button and then fully pushing the grey switch back up?

 

[tellytv]

yep, didn't work

MCB's (the little grey leaver) are designed so if there is a fault you can't force it to reconnect even if you can put the lever up.

Likely you have still got the fault so it will not allow you to re-energise. You will need to turn it off to re-set once you have found the fault.

the new spotlights I put up I have now taken down again and left the wires hanging?

could that be the problem?

If yellow test button does not work that normally means no power coming into the house.

Putting wires each in it's own connector block should mean these wires will not cause it to trip but it will likely also remove the supply to all lights further down the radial.

If the RCD is already in its 'operated' state (it seems that it won't reset), the test button would obviously not do anything, even if there was power in the house.

Kind Regards, John

It is sometimes necessary to firmly push those levers all the way down before they will reset when you push the lever back up - have you tried that?

Kind Regards, John

the grey button tripped,the yellow buttom works, however lights still don't work, I've taken the lights down so just got the wires hanging so I'm guessing thats why the lights aren't working because theres live wires hanging and not in a connector?

this is how I wired it up

the earth cable had 2 wires with 2 ends in it?

Where do those red and black wires which disappear into the ceiling go?

Kind Regards, John

 

[tellytv]

no idea as it's a flat roof above

 

[ericmark]

I would guess those two wires go into a connector block. Have they been pulled out?

Quite so - whatever is on the end of those two unsheathed conductors could well have been given a yank - with goodness knows what consequences. It is clearly not a satisfactory state of affairs.

That's 2 earth conductors, one from each of 2 cables.

And they should both be connected to the earth terminal of the light - why aren't they?

Not entirely clear from the pic: is the red wire connected to the brown ones and black to blue?
