    Spur from Ring Final Circuit

    My last thread was taken down due to copyright reasons, I think it was because I scanned a page from the wiring regs and posted it. Can anyone tell me if this circuit design conforms to regs?

    Ring final with 4mm legs

    So I have been working on a four storey house, in which the wiring is pretty sound, the sparks who did the last rewire (approx 2004) seems to have loved 4mm T+E, all the sockets are on 4mm radials, with either 16, 20 or 32 amp breakers. The exception is the very top floor sockets, which he did...

    Final Circuits Non Dwelling

    Having gone back and forth through the onsite guide and BYB, am I right that with socket outlets in commercial premises it is the same as domestic 2.5mm and 100m2 ring main and 75m2 for a 4mm radial circuit? So application for diversity would be 32amp for first circuit and then 50% of every...
