3amp FCU Tripping

[SO1]

customer asked for a 2g socket and single light to be put into her outhouse which was connected to her kitchen, as there was no power there i had to take a spur off the existing kitchen radial circuit into the outhouse, i took it from the spur to a 13amp FCU onto a 2g socket then onto a 3amp FCU then onto a single 60w lampholder. everything worked and tested fine when i left but within 24 hours the customer rang me and said the 3amp FCU had blown. any ideas?

Probably best to ring a local electrician.

 

[davesparks]

Plenty of ideas, some of them will probably get me told off by the moderators.

Have you been there and carried out any testing to establish what has happened or why?

I'd start with confirming that the fuse has indeed blown and not the lamp

 

[Leesparkykent]

As above....there is obviously something not right so would be best getting a local electrician to take a look :icon6:

You would be surprised how often I fit light bulbs and they are knackered. I always fit Osram Eco halogen lamps, I picked up three, two didn't work. Another time I fitted two, just as I was leaving they switched it on and one packed up.

Lamps not bulbs you plant bulbs, really uk

Hi SO1 - your post history shows you were taking your level 3 about 3yrs ago, can we assume now as you are taking on paid work you are not DIY or even Trainee but an Electrician?

When you did the work did it all test out correctly as is required for the cert' provided to the customer?

If so then I would assume the lamp blew taking out the 3amp fuse, has your customer tried putting another lamp in?

 

[GMES]

Darkwood beat me to it for a change :ciappa: I am also curious about your competence level and what stage you are at quals wise, once we know those things we can answer accordingly, I just hope you are not still in training and doing paid work while unsupervised.

Sorry Pete, it will not happen again.

Oh Pete you're like a bear with a sore.............:smilielol5:

 

[uksparks]

If the fuse has blown hypothetically, clearly it's been overloaded, maybe the lamp blew and caused the fuse to go.

 

[Octopus]

What were the test results for the circuit you have modified?

 

[Pete999]

Stop it lads, I would be surprised if there were any tests, only the bang one.

 

[Flanders]

Just a thought how does the customer no the 3 amp fuse has blown have they tested it ? This all seam very odd that a electrician is asking this question

 

[Pete999]

elementary, my dear Flanders, elementary.

 

[Flanders]

I only said this because i was called out years ago to a bown fuse only to find the customer was using old blown bulbs (sorry i mean lamps)

 

[Dave OCD]

So simple [I bet]. Dodgy lamp blows taking out 3 amp fuse, customer assumes just bulb replaces and it doesn't work...

 

[shanky887614]

put a 5amp in its less likely to blow. 5amp are black i think

If it was a Radial, why have you spurred off it? Surely you just add another socket to the radial, then fuse down with an FCU for the light

 

[Risteard]

5amp are black i think

All except 3A and 13A are black. That is because 3A and 13A are the only recommended ratings in BS 1362. It also means the characteristics of other ratings may vary between manufacturers.

He's not wrong;

 

[Andy78]

I get the feeling that any fuse used on this job may end up black anyway.
