Lighting wiring

[aok86]

Switched on ceiling light recently and went pop, and fuse tripped.After resetting fuse, light did not function,changed blown bulb and still didn't work.Light is connected to a double switch and other light connected to switch works.Decided to get a simple ceiling rose as I assume the old light is faulty.Having trouble connecting it up.Tried : 2x black to blue and single black to brown.
Any help/advice appreciated.Tnks

Tried : 2x black to blue and single black to brown.

That's probably right - those pieces of choc-block look as if they are replicating the connectivity of a standard ceiling rose with loop-in wiring. Where was the old light connected?

But electrical installation work by assumptions and guesswork and trial-and-error is inadvisable - you should get a multimeter and test what's going on at those connectors. (All of which should be enclosed, BTW, not stuffed loose into the ceiling.)

Have you looked at the wiring in the switch?

Yes, Get yourself down to Maplin. There will be some bargains to be had.....!

Well, the picture of the light shows that the terminal screw was on (but through) the insulation.

So, if you have done that again, it may not have gone right through the insulation.

Is it a dimmer switch?

 

[aok86]

yep ,dimmer switch

The switch is destroyed - buy a new one.

What makes you think its the dimmer switch?

1) It is a dimmer switch.

2) You had a bulb fail with a large enough current surge to trip the circuit breaker.

3) Dimmers are notorious for getting fried under those circumstances.

4) Visually there is nothing wrong with the wiring at the broken light position which would account for it not working.


You can test the dimmer switch by swapping the wires from each side to the other.

Tnks for your suggestion,re swapping the wires.Tried that,and the light that did work no longer worked ,and vice versa.
Off to get a new switch.
Thank you very much for your input.much appreciated.

Good job this:

wasn't a big investment.

Its always best to rush out and buy as much stuff that MIGHT be the item at fault, without actually testing what the fault could be.

Yes empty the shelves! Then test.
