Tell us about your faults!

Re: Tell us about your faults !

Got called to a house where the tennant was getting tingles from her sink. tt installation and the previous occupier had cut the main earth cable from the rod and strung it out to a tree to use as a washing line.

Do I win a pen?

No, sorry, you don't win a pen.
No where near being silly enough for a prize :-D

went to a house where the water coming out of the tap in bathroom was live 230v earth boned run to nearest socket unfortunately they run it to the live wire

when I worked on Faith Zone on the Dome.
time to turn some circuit on (you know guy jobs pressing and all that, it'll be tested later)
the circuit is energised, and the lights don't work
we pull apart the Klik rose and still no supply
double check the cable makings, and all should be good
we decide that it must be a dodgy MCB and so decide to change it.
removing the Dist board cover I see for the first time the fault.
On the Merlin Gerin Isobar4 range there is a slider which Isolates the MCB.
This is a safety feature so that the exposed busbars (when a MCB isn't fitted) is not live, and so we can change an MCB on a live board.

I have worked on loads of these boards since then and like them alot

(btw I didn't put the board away that was someone else)

i went to a house that had had a fire in a bedroom many years before .so a new plaster board ceiling had been put up when i went into the attic the rubber live and neutral which had been burnt then over the years had craced ,so there was a bare live and neutral latind across the ceiling millimetres apart

The girlfriends dad rings me up the other day saying theyve got no upstairs lights in the house working! I asked him if the MCB had tripped maybe due to a lamp blowing? He said no the MCB is switched on! ok so I said id come and have a look for him, so the first thing i checked was if there was power on the circuit side of the MCB, my voltage indicator was showing 0V! Strange the MCB was on, I switched the MCB off then on and retested, now showing the correct voltage! I later found out that my girlfriend had switched her bedroom light on first thing in the morning and a lamp had popped in the fitting and tripped the lights, but she didnt decide to tell me that! Quite an easy fault the breaker had tripped but not operated the switch on the front, must be a faulty mechanism! I changed the MCB for a new one just to avoid any confusion if it was to happen again, never came across this myself!

Just a thought, does/has the hoist been used anywhere else where the outlet doesn't have an RCD?

To what fault is your question directed at mate?

Hi Clicon: Possibly your post #631 about the roof hoist ?

Did you get the fault sorted in the end ?

Thought so, wasn't sure. Not working on it personally but the fault seems to be not on the 400V winch or it's 230V control gear but with a supply flat cable on a catenary. They have managed to get it working and NOT tripping with a 30mA RCD in place fed from known "good" cabling. Trying that same RCD on site with the now suspect feed cabling and it tripped continuosly.

Faults in situations like that can be an absolute pig to find at times, did they remove the 500ma RCD in the end & just leave it with the 30ma ?

It's not all back and running yet. Will update when I hear. Hopefully if they find where its going down and fix that they will be able to leave the 30mA in place.

Situation: Light not working in 4th floor bin chute room
No power to light fitting
Nothing tripped at FB
Power at switch
all over floors bin chute rooms lights working??
What am i missing?

 

[Specialist]

How is it wired, 1 switch for all lights or independently switched ?. When you say it's dead whats missing, Live or Neutral ?

Cheers mate, i'd be interested to find out how it turns out.

 

[jamminuk]

Thanks specialist - Each chute room has it's own switch, it's just dead at the fitting, no power, but there is power at the switch. 2 reds at the switch but at the fitting 3 reds and 1 yellow in one connector block then a black with red tape, neutral and earth going into fitting

 

[Specialist]

So are the 3 Reds & 1 yellow the switch return & L loops out to other fittings ? If you've got live In / Out at the switch but no live at the fitting, have you checked for any joints inside conduit boxes that might have come loose ?

 

[jamminuk]

Well that's what i would assume, but if there are 2 reds at the switch where did the black switch line come from? As you say there might be some joint hidden somewhere but It's all plaster boarded up, must admit i was a bit rushed when i was there, ran out of money and the van was in a pay & display, but to tell the truth even if i wasnt rushed i'd still be there scratching my head now! Checked at the fittings on the floors above and below to see if anything had come loose but nothing!!

Went to a house yesterday and found a CCU that the user was expected to insert little pieces of wire into and then screw it down at each end to act as the fuse.
Crazy Idea!
