Discuss Dead Circuit in the Electrical Wiring, Theories and Regulations area at ElectriciansForums.net

Lets carry on that excellent piece of advise and start the ball rolling (assuming getting replies off jimfuego)

Quest 1 ( in my best July Andrews tone )

Was there a shilling in the meter ?

the hills are ALIVE with the sound of music or maybe not in jimfuego's case!
 
I am going to apologise to jimfuego for my tasteless humour

jim, Have this thread back

Humour leads me astray I'm sorry to admit

Now tell us, what is the answer to the mcb issue ?

If you've already checked each accessory and switch, disconnect at each point and do a continuity test to find the damaged cable or connection.



I am 17 turning to 18. Was that a song in the sound of music?
 
which could obviously be virtually impossible to find - especially as the customer has recently insulated the loft and and boarded over part of it.

It seems there are a few discrepencies that need to be attended to before further advice can be given. Your results are showing a fault on line and neutral conductors but no answer has been given to suggest that lamps, transformer packs or even dimmer switches have been removed from the circuit.

The other point I will address is the "Virtually impossible to find"??? Why is it? DIVIDE and CONQUER! You will find which accessories the fault is between, if you do not have access then explain to the customer that gaining access to continue your fault finding will still be charged at your hourly rate, when I suggested this to one of my clients they were in the loft like a ferret moving insulation and boards in order to assist (genuine customer though and probably quite rare these days;)):thumbsup
 
Hi chaps/chapesses

I have also done an Insulation Resistance test on the circuit and am getting a reading of 0.00Mohms on L/N, and about 4Mohms on L/E and N/E.

If your getting 0.0M ohm L-N and the MCB is still on!! then its one of three things.. either a lamps in circuit still and your testing through that,(this will give the reading but wont answer why no supply) or the cable really has gone down.(this would give the reading but also trip the mcb) or a failed MCB. (open circuit when in the on position) Im guessing dodgy MCB and lamp in circuit..
Good Luck.

doe a deer a female deer, ray a drop of golden sun!!
sorry its in my head ile go stand over here....

Morning chaps

Apologies for not replying sooner - having posted late on a Saturday night, i didn't think i'd get any replies til this morning!

So - a): i did check the voltage coming out of the MCB (with a voltage tester :wink_smile:) and it was reading 240V - a faulty MCB was my first suspect - but no voltage at accessories.

b) the customer stated that when he boarded out the loft he raised the finished floor level up by using 2x4 struts on top of the joists, and that he worked round any cables he encountered. i can see that he has raised the floor and i trust him on the cables (he's a builder).

c)
:oops: schoolboy error on the insulation resistance: took all the bulbs out on the circuit, but now you mention it forgot to isolate the transformer pack for the shower light...

d) 1shortcircuit: "The other point I will address is the "Virtually impossible to find"??? Why is it? DIVIDE and CONQUER! You will find which accessories the fault is between," " & sidecutters: "If you've already checked each accessory and switch, disconnect at each point and do a continuity test to find the damaged cable or connection." - this is what i had started to do before it got dark yesterday and which i will continue to do to try and pintpoint the faulty bit - so you're right: not 'virtually impossible'.

i was just a bit worried that after 90mins work i had no answers for the customer, so was just asking the question on here to see if anyone had any suggestions - so thanks for all the responses.

Going forward, i'll double-check the MCB and carry on with the continuity testing - whistling "The Sound of Music" as i do so...

cheers
 
If you say that there is a supply leaving the MCB but nothing at the lights, then its really gota be at the first on the circuit, or the cable run from CU up to first point!!
again good luck..
PS dont leave us all hanging when you do find the fault, theres nothing worce than reading all the advice then never hearing what the out come is..

That'll be how you solve the problem, like Maria.

How long can we get away with references to the sound of music before we get shouted at for going off topic?
:)
 
well, julie had her gestapo, we've got moderators ( sorry, mods, only joking):furious3:

Thats where id be checking ! also could redo connections as its like the pencil lead it could have a break even though it looks ok ! discon from cu and test at closest light on circuit i recon to.
