fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me nuts

[aabbcc112233]

hi there

my downstairs lighting ring fuse blows randomly sometimes instantly sometimes in 10 to 20 mins. ive tried a multimeter continuation test to see if there is any contact between earth and live and neutral and live on that circuit . which there doesn't seem to be.

there is continuity between earth and neutral . this is also at the consumer box . only this fuse blows. ive tried opening up sockets and checked them for any obvious signs as well as light roses as well.

its driving me crazy.

cant seem to find the fault

any help on how to find the problem will be much appreciated. by the way the fuse first blew in the middle of the night.

Do you mean switches??

Sorry to state the obvious, but call in a local electrician

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

time to get a sparks in with the relevant test equipment to trace the fault. a multimeter will not find the fault unless it's a dead short, and even then, doubtful. imago's in your neck of the woods.

sorry mate you are right i mean switches not sockets

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

Water ingress, heat damage, rodent damage, knackered cables, knackered accessories.

One of the above probably.

A spark with the correct test gear will locate the fault bud.. Just bite the bullet get some that can find the fault..

I'm not far if you need a spark to take a look

have you got any outside lights on the circuit or done any DIY recently

 

[aabbcc112233]

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

no outside lights and no diy done recently mate

Then it could be a number of things.. Sedgy 34 is local.. Get in contact with him.. With the right test gear it will narrow down what the fault is..

 

[sedgy34]

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

So a fault has just developed??? Can you post a pic of what's tripping in the distribution board

 

[dan86]

I see you're a student electrician. but yet you got sockets and switches mixed up. lol!
sedgy34 is obviously near to you.best get him in and mebbe watch him as he pinpoints the fault. you may learn something..!

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

second white fuse wire from the right keeps blowing. have to replace it with 5 amp fuse wire each time

 

[bigbaddave]

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

If its taking out a rewirable then its overload or dead short.. Unless you can pin point it to a persific light or switch then without a tester then its trial and error..

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

If it taking out a 3036 it a wonder you cant see or hear where the fault is

Wow.old school!
you obviously have a short circuit, probably caused by heat damage in a
Light fitting. could even be a dodgy bulb...

Can of worms have been opened lol

Im sure a man of your caliber can have it traced+rectified all within a few hours Sedgy. maybe even give him a cheeky discount for being a member on here...

 

[Guest111]

Re: fuse blowing randomley somtimes instantly sometimes in 10 to 20 mins driving me n

you will get continuity between neutral and earth,unless you isolate the board,this is due to neutral and earth being connected at transformer,please note this will not apply if TT system.

don't you just love that circuit identification.

Very true but this chap wants someone to tell him were the problem is without paying

Surely you don't charge for several hours of your time if you're only "having a look"

a big dirty rat has probably had a nibble at one of ur cables , seen it happen loads of times , keep us updated after u get a spark to have a look at it and u may aswell get him to change ur DB while hes there lol

he doesn't want to pay so will probably not get one in and keep changing fuse wire!
and yes, DB looks like its seen better days!

Thats one expensive call out then. You suggest new consumer units on all jobs with rewirables?

Lol I've been one of those busy fools

no mate i dont do a lot of domestic work and this post is one of the reasons y , a painter will go to someones house and paint sum rooms , take 3 or 4 hours and charge the 200 quid no questions asked , a spark will go , trace a fault or wire up some lights , may take a few hour coz u always run into problems , then say lets just call it 100 quid and the customer will say but u only put up a few lights and fixed a fault , aye but i had to lift ur floorboards and wire a circuit for them the dip into ur live dangerous fuseboard so u wouldnt miss eastenders , they are all the same , wish ad beed a painter

I get real suspicious if these threads now, don't know if its someone playing silly buggers or for real, look at the username ?, a student would have something more "electrical"
Look at the bad terminology!
"Lighting ring", "continuation", "live" (line) and using a multimeter ??, sorry don't buy this onw

Hope that 30amp fuse on the end isn't feeding the kitchen ring or his washer and stuff will all be going backwards !!

Anyway washing machines and tumblers rotate both ways so it will only be his food mixer and lawnmower that will be going backwards

I'd be worried that it would freeze the water in my kettle.

Or defrost your fridge ...........................

Music would all be backwards too..............not that I'd notice with today's garbage lol

The lawnmower would put grass down - could be useful that. Daz
