[dave992]

Hi, just wanted to start this forum, for any unusual, or faults that you don't come across ever day.

There seems to a fault on here that happens alot.

Its the "I went to look at a RCD/MCB/RCBO keeps tripping fault, what could be causing it?" Without actually dong any testing and then thinkng we can solve it for them fault.

10 o'clock every Sunday in a pub the RCD used to trip no other time just 10 o'clock ,go to the RCD reset no problems till the following sunday after 8 weeks of it just tripping the once i was called out to it and found it was a damaged cable where a rat had nibbled the insulation and drips from the beer tap dropped onto it, why just 10 o'clock on a sunday ill never know.

I had one of them every day at eight pm the house would trip got there tester all ok in the end it was a time clock but it went passed the fault so it was always clear

Had an alarm that went off at 4pm every day,the lad that fitted it had run one of the cables alongside the cable from roomstat and heating fired up at 4 pm.This caused an induced into the alarm cable and set it off.

Had a room dedicated to a UPS. it had an A/C installed as well as an emergency stop by the door (50v) every time every time the compressor kicked in out would go the UPS took us some time to find the problem, compressor kicked in induced a voltage into the stop circuit switched off the UPS twisted screened pair soon sorted that little issue out

smoke detector bleeping on a new build ive taken the head out and the battery and the base was bleeping said the customer ..................... smoke detector in a cupboard that was bleeping with flat battery

 

[gutterball]

I had a similar one, called out to a smoke alarm beeping. definitely not the smokes, not the co. what was it? The dish washer beeped every 30 seconds or so when the cycle had finished.

 

[telectrix]

had a few call-outs to intruder alarms that i had installed. customers complained it was bleeping. each case was a smoke located close to the alarm panel.

Called to a recently rewired property a couple of weeks back, no certs and installer now no longer answering calls.
Gas fire with a back light in it but the back light now doesn't work, until you turn the thermostat up.
The couple paid £3k for the rewire, I'll be taking a dig into it soon. I think it's safe to assume there'll be one or two remeds.

Extractor fan 'stays on constantly'. Got there at 7.30pm after long day and received 'frosty reception' as it was obviously something that we had royally f'd up. Should have seen the look on their faces when I pulled the (previously demonstrated) chord!!

Surely Trev, if he was having to show them something it would be good old C Maj? [emoji41]

Built in fridge isn't working.

Genuine call out about 3weeks ago - the cheeky 'bread bin' had obviouslly been knocked and turned the fuse-spur for the fridge on the worktop off behind it.

Customer was red-faced, i had a chuckle and everyone lived happily ever after.

 

[ferg]

cooker stopped working.

eventually tracked it down to customer hanging a picture over the isolator and the picture switching the switch.

customer had no idea what the switch was for, had never used it and assumed it was no longer used.

in fairness it was on a diferent wall to the cooker.

 

[dingledong]

Must have been high up then this isolater

and you charged them an hour for wasting your time yeah?

 

[gutterball]

I've had that a few times with spurs in cupboards full of crap.

Yes it was. It was in a ridiculous place for a cooker switch TBH.

The conversation went something like ..

Where is the switch?

There isn't one.

Have you done anything just before it stopped working?

Just hang this picture.

Remove picture, switch on, re-hang picture, laugh, finish coffee and drive home.
