Hi,
Some ideas where to look please!
Here goes. I am changing 3 light fittings in a bungalow. Above one light, in the loft there was a junction box, the cpc wires were cut back and not used. (both from feed wire and to switch).
Before connecting up the feed to the light, I terminated it in a separate junction box to test the supply. Using my Metrel 3215, I measured the supply at that point.... The readings were:
(From memory)
L-E 104V
L-N 232V
N-E 128V
I was expecting the N-E voltage to be close to 0V.
I suspect that there is a lose connection for the cpc or the neutral in the circuit somewhere.
The circut is difficult to trace in the loft, if i cannot find a poor connection, I am considering running a new feed to the 5A MCB for that light.
Any ideas welcome! Not too harsh please.
