Lighting problem

[Cirasha]

Hi, I returned home last night to find the lounge ceiling spotlight fitting had blown a bulb. This, of course, flipped the fuse out. I reset the fuse in the fuse box and expected all lights downstairs to come back on except for the faulty bulb but downstairs remained in total darkness! Any ideas anyone? I'm fully expecting to have to call an electrician but don't want to do that on a weekend!

most likely there was a poor connection in the lighting circuit, either in the consumer unit or more likely one of the ceiling roses. The power surge from the blown bulb probably causes this poor connection to burn through. There is a faint chance that there is a junction box hidden away out of sight under the upstairs floor (this is not permitted) which will make it more difficult to find and fix.

Lighting circuits are run in a long chain (not a ring) so everything beyond the point of failure will then lose power.

If you want to look at the ceiling roses from a stepladder, be sure to turn off at the consumer unit. Ceiling roses are still live even when the light switch is off.

Don't remove more than one wire at a time from its terminal. All the wires have to go back in exactly the same place, and even if they are the same colour, on a lighting circuit, they are not all the same.

An electrician will be much quicker to find and fix.

We had this happen and it turned out something had gone in the dimmer switch and one transformer needed replacing. The good news is when the electrician came round it took him about an hour to diagnose and fix , so not a majot job. Not technical but from your description it sounds similar to our situation

Thanks for the info, appreciate it!

Thanks, worth checking out!
