We had major work done on the house a couple of years ago. This
included, amongst other things, a loft conversion. When the electrical
wiring was being done we had a new consumer unit installed. The
builder used various sub-contractors including an electrician - in
whom we did not have a lot of confidence. This scepticism has been
borne out by a legacy of problems.
A new electrical problem surfaced yesterday and I wanted to air it
here to get your views before I take issue.
A light bulb in a ceiling fitting in the loft blew. This is in one of
two light fittings on the same circuit. I replaced the bad bulb and
switched on the wall switch. The was slight click and neither fitting
lit up. I went to the consumer unit and turned off the supply on the
circuit for the lights in the loft. I came back up and to be safe, I
put a voltage detector to the fitting and was surprised to hear it
beep. I toggled the light switch and in both positions and the
detector still registered voltage.
I thought then that maybe the circuit was mis-labeled. I then turned
off various circuits and found that the voltage disappeared only when
the circuit for the 13 amp sockets in the loft and the loft lighting
circuit were both turned off at the same time.
I kept the circuit for the sockets off then put two new bulbs in the
light fittings. I switched on the wall switch. Only one came on. The
original bad one was still not working.
I'm not an expert in electrics but something here just isn't right -
to put it mildly.
What should I do next to check things and to try to get to the bottom
of the mystery?
