Hi ALL
Just thought id put this one up for all those faults we find.
heres one to kick it off !
Domestic RCD tripped and wouldnt reset cause was a blown low energy light bulb.:D
There you go now for yours !
 
Simple job today auto drain solenoid on a compensation vessel had stopped working after a recent fire on site. It was obvious the cables had been damaged and replaced and whoever had done it must have forgotten to replace the fuse.

Ok walk to the substation I'm pretty sure has the DB that the supply comes from. Check all the boards no sign of where its fed from.

After half an hour of tracing the cable back to the same sub I found where it was fed from. Out of a 63A Red Spot DB marked up on the front 'welding socket supplies'

Whoever put it in, to give them there due, had used a correctly sized fuse and marked inside the door.
 
Oh and I found this in the sub, our very own guard rat. Must have touched something it shouldn't and someone stuck him to the top of a piece of switch gear.

Re: Tell us about your faults !

View attachment 10917Following a rece
ection i found this breaker supplying a single phase board.

i wish i had thought of that for the old boards with obselete breakers. can i strap a match between 3 single phase ones and use as a 3 phase? obviously i would make sure they are all rated the same, couldnt have a 32, 16 and 6 as that would just be unprofessional!
 
I’ve had a 11KV board explode due to vermin getting in to the bus-bar chamber. Anything that gets rid of them is OK by be.



Got in sever trouble on a Norwegian north sea crossing. The crew didn’t like us squeezing calcium carbide into a ball of bread and throwing in to the air.

Not our fault the seagulls would swoop down and snatch it before it hit the water!

Do a bit of chemistry and you’ll work out the result.

Gets rid of vermin! QUICK!
 
Re: Tell us about your faults !

Good morning,
I have got silly trouble,I am foreign electrician and try apply for ECS card ( I have passed my test)but I cant really fin anyone who could write me a recommendation as it need in section 10 in application form.I have tried to reach the companies which I worked in past but some of the doesn't exist anymore.

Re: Tell us about your faults !

This one has baffled me (doesn't take alot): I've been called to a house that has a problem with the upstairs light circuit's cpc being live, enough to detect a fault on my voltage tester but not enough to light a neon. The stair well lights, which are on the downstairs circuit are also cpc live. The rest of the downstairs light are good. There are also 4 sockets with the cpc live(non of these are adequate to shock nor trip the RCD). I have checked the wiring on all light switches and roses, Extractor fans and shaving points, I have checked all visible wiring in the loft and apart from some dubious use of some chock blox where the owner has changed light fittings(which I have checked and ensured they are now safe) I can not find the fault. I'm obviously missing something but don't know what. Any ideas? Also, the MET is showing no voltage.

When you say you are getting a live voltage on the cpc's of circuits, What voltage are you getting and what are you checking it against as a form of reference and what instrument are you using.
I ask this as it will help us identify the possible fault you have.
 
Re: Tell us about your faults !

I'm getting between 60 and 70 volts at each earth terminal. I'm using my mft to determin this. I'm also checking with my led voltage detector. I've carried out continuity with readings ranging from 0.45 ohms to 0.6 ohms.

Your still not saying what you are testing between, obviously cpc and...........?
you need a known true earth supply to give you any true voltage on what you are testing, more so when faultfinding.
Tels idea is the best.
