Lighting circuit wired strangely

    Hi there, I've recently purchased a property and have started to move two light switches. I took a look at the wiring in the attic last night and discovered that the lighting circuit is all wired from one junction box, each light then has a feed going to the switch, from the switch to the rose and then a neutral from the rose to the junction box.

    I get the feeling I'm not allowed to wire this in the loop in method so what would the best plan of action be right now? I'm planning a rewire in the very near future anyway.

    Sounds like an Octopus system.
    How big is the junction box?

    Large circular one, probably roughly the size of a saucer. Couldn't get any markings from it but the house is littered with them so I'll take a look at others later.

    That method was used in older houses before the advent of loop-in wiring.
    It’s perfectly feasible to add or connect to this, if you know how it works.

    As Bazza, Any decent electrician would have marked the cables to A, Assist during the installation, and, B help during alterations or fault finding, I always do if I have the misfortune to come up against this wiring method.

    But if it was the 'Octopus system' it was not put in by an electrician, just a trained fitter. The whole Idea of this system was to do away with those 'Expensive' electricians.

    What gives you that idea Bob.I have seen them put in and put them in in a lot of sites in the seventies,all installed by Electricians,with or without an Apprentice.

    No semi skilled people were used.

    Once I'd unearthed all the cables from the horrible old insulation, it was self explanatory. Don't think it was octopus as from what I understand, they were prefabbed units where as this was a simple JB.

    Gone for a rewire anyway!
