I have a problem with a light tripping a rcd etc.

All the circuit tests out good.
No tripping when a bulb not in and voltage is correct when i put across L and N
When i place a bulb in the fitting it trips.

Any ideas chaps ?
 
yeh done all that. I replaced with a pendant etc. It still trips the rcd.

The strip light in the other room is at fault tho as it wont strike up so do u think it could be due to this even if the switch is off blah blah.
 
Yeh i changed 3 lights for them nasty wire crapy grrrrrrrrrrr take ages to wire lights lol

all other lights work fine tho

Maybe a loose N do you think in a fitting ?
 
appears to me the pendant neutral is connected to a cpc

a n-e IR fault would cause additional symptoms

could be wrong of course

whats the wiring arrangement?

is it a low energy bulb ? ive had one go and trips the rcd but didnt let you reset it with bulb still in ! for the sake of 5 mins its worth testing all low energy bulbs in a table lamp.
 
Ok

Looked at the job today

What i have is a pendant that trips the rcd.
After looking into this i found a N that leads to nothing.
Looks like this N should be connected to a pendant after belling out etc.
My thoughts are this N is not connected to this pendant i found and the pendant then leads to a terminal j/box will this cause the other pendant to trip out.

I think the N must lead to a j/b from the light fitting and the loose N leads to d/board.

So my plan is to link this N to the pendant and things should work !

Any ideas chaps ?
 
yes rcd working fine.

Cant think of anything else.

I belled out the wire between the fitting and N and all was ok.
this light also dos not work ,so makes me think if i link this N up to this fitting it will give me te radial ?

what ya think ?
 
swap the fitting with the one that works and see if the RCD trips then if so take out the suspect fitting leaving the one that works in and terminal block where the suspect fitting was so the circuits complete less the fitting
 
Think methodically,the more you stress out about it,the less likely you are to find the fault and repair,so deep breath,and start by halving the circuit,disconnect all conductors to furthest point say,leave in place from ccu to that point,still trip?no,then that half is ok,then move further down circuit,i dont know how much experience of fault finding you have,but once you have found and fixed it,you will say to yourself that was easy,are these all existing fittings and wiring or has it been altered and now does not work?
