'lights' circuit not working

[graykev]

When turning on the kitchen light this evening all of my other lights went out. All other circuits are fine. Just every roof light not working. Thus has happened twice in 3 years and every time I just replace the fuse wire and problem solved. However when doing that this time the fuse is still in tact. Also when I put the fuse back in I usually get a small spark but this time it's completely dead.

Can anyone suggest what the problem may be that I could fix?[/img]

Hi, have you done any building work or changed a light fitting recently ?

Nope. No change at all. The house has been vacant for around a week in the cold weather is that could effect anything?

Hi, no i would have expected if it was water ingress or dampness in the wiring it would have blown the fuse. If you are confident with electrical work, i would remove the cover from the CU and check the connection to the fuse holder supplying the lighting circuit is tight and the cable is not loose.

SWITCH OFF AT MAIN SWITCH first !

OK. I plan on checking the outlets closest to the CU at both the light switches and light units to check for loose or burnt out connections. I will also try your suggestion aswell.

I'll report back once I have did this at the weekend.

Thank you!

Kevin.

Hi, are you sure that the fuse is working do you have another 5A circuit you can swap the fuse with to check ? 5A wire sometimes snaps when you tighten the screw on the holder.

I'm not 100% on that but know that the fuse wire is intact and making contact with both screws at each end.

How much lighting on that circuit?

Thus has happened twice in 3 years

Just when you turn lights on? Not when a bulb blows? That's not right.

Also when I put the fuse back in I usually get a small spark but this time it's completely dead.

Never, ever, EVER do that again.

Insert a fuse when the circuit is live, that is.

Possibly someone here can post a photo showing what can happen when you insert a fuse against a fault, so you can see the fun you might have.

Will this do?

2 lights downstairs and 4 lights upstairs.

Only when turning switch on. On one occasion the light bulb smashed when turning on the upstairs Hall light but has been OK ever since. On this occasion the kitchen light caused the trip.

Also when I put the fuse back in I usually get a small spark but this time it's completely dead.

Point taken. I will turn off the main switch from now in prior to removing and reinserting the fuse.

So any thoughts on route cause?

Sorry, I responded in the above reply. May have not quoted properly as sending from mobile device.

2 downstairs and 4 upstairs.

Hall light down stairs, kitchen lights (they halogen or other? How many bulbs in kitchen again?) two/3 bedrooms upstairs with one light each and bathroom.

Hall light both upstairs and downstairs are normal filament bulbs. Kitchen is a 3 bulb halogen, bathroom is 2 halogen celing bulbs. Both upstairs bedroom are normal filament bulbs.

So with all the above info, does anyone have any ideas on what the cause might be or what I could try?
