Hi All I am replastering a ceiling and i have taken down a landing light now i have a question there are three black wires going to natural one red going to live and one earth, i turned off the downstairs lights at the mains unit and this turned the light off. When taking the wires out of the connector block i got a belt, was this wired right and have i done something wrong? Thanks for your time.
Landing lights often (wrongly) use borrowed neutrals so that your downstairs and upstairs lights are connected. To be safe turn off the whole mains unit while you reconnect the light. There should be a label saying 'Main Switch' next to the isolation switch.
If the system is suspected of having a borrowed neutral..maybe call in a sparks to ***** the situation?.. http://www.niceic.org.uk/downloads/N5-1.pdf
Thanks for your replys. What would have to done to make it safe in the future ? Does it mean a lot of work and money
Maybe even a neon secrewdriver would of helped in showing that a wire was 'live'... Or the practice of using insulated tools and not touching bare wires ...
