    Consumer Unit Query

    Hi Lee, Should there be a seperate ring main for the kitchen?? The cooker is seperate but then only 1st and ground floor ring mains. Most domestic systems evolve, looks like your friend's has too. Hence less rings than in a modern install. (rewiring my 30's semi recently ended up with...

    Was who ever did the wiring in my house on drugs?

    I'd seperate all of the connections at the main light from each other (but leave everything else as it is) and then test / inspect to see which cable is which. There should be a supply cable (you can test for this by meter, or by attaching a lamp holder to every cable end. When you restore...

    Extending Consumer Unit

    Have you got a split load board or RCD of any type? If so and you'll still be under your consumer unit's RCD's rated current capacity, run extra tails from the RCD to your new board & rearrange the trips to suit. An electrical wholesaler will sell you the copper bus bars for about £1 each if you...

    RCD Nuisance tripping

    can you make a disconnected light lead safe?

    Yes, but you might need to make a bigger hole! Best idea is to trace through where the cable is fed from (ceiling roses in the vacinity are your best bet) and disconnect it there (if you do trace it to a rose, connect all of the cores to earth at the rose, and twist all the cores together in the...

    Double switch

    This is fairly straight forward especially if you have ceiling roses and there is an existing working fitting. If not, let me know and I'll advise a little more... The circuit for a single switch will be N direct to the fitting, E direct to fiting and down the switching cable, live to the...
