A bulb in a wall light blew the other day – there was a bit of a bang, but the fuse on the consumer unit didn’t trip. So just stick new bulb in then – nope, nothing!
The lights are in a conservatory and there are are two wall lights on one switch and 2 outside lights operated by another switch. Neither of these now work and there seems to be no power coming into the back of the lightswitch.
But all the circuits seem to be working – lights and power!
When the sparky did the wiring for this I suspect he spurred the wall and outside lights of another light circuit as there were only 4 extra lights (he put a new power circuit in).
Could there be an in-line fuse in the floor somewhere to protect this spur?
Or could something else hidden have blown?
I’m baffled now!
