    as i have posted recently that two of my upstairs lights have stopped working,the feed back i have had suggest a possible neutral problem,as i said also i have been decorating aswell,the two lghts not working were not where i was decorating,the bedroom i was working in the light works,i have not checked the wiring in the two bedrooms where the lghts work,can anybody explain how a loose neutral,if that is the problem on say a bedroom light would effect the two lights not working,and if this is the case why would the bedroom lights still work if that was where the loose neutral was??????

    Lighting circuits are generally radial circuits, meaning they originate at the consumer unit, then go to point a, point b and so terminating at point x

    If you have a loose neutral on the outgoing cable from point c, point d, e & so on will not work as there isn't a full circuit, but points a, b & c will work fine as there is still a full circuit.

    I would check the bedroom light, see if there is a loose connection to that as the loose/broken neutral could be on the outgoing feed, with the feed in being fine

    In the UK the ceiling rose doubles as a junction box and the supply is daisy chained from one ceiling rose to the next.

    Common failure reason is DIY guy thinking all black wires are neutral when in fact often one is line. So common to find DIY guy has got them mixed up.
