    Ring or radial in bungalow

    I’m rewiring a bungalow and the owner has asked for a radial for all sockets except the kitchen. But there will be a separate washer and dryer in the circuit. Will a 20A radial be enough?

    Have the rules for ring mains changed over the years?

    I am sure when I qualified for the 16 edition we spoke about how to treat a ring main. I know the majority of the time we just learned how to read the book and how to find needed headings but I am sure we also spoke about ring mains. If a socket has two cables coming into the back box then it is...

    Wiring Ring that has already been bypassed

    Hi folks, cautious DIYer, so just looking to confirm something. I got a wired Ring for our neighbors who have been without a doorbell at all. Seems the previous owners had had some sort of smart doorbell system and took it with them. When I got to the part with the chime box it looks like...

    Ring Final Circuit - spurs only

    I read that it is against the regs that a ring final circuit cannot be just a ring with with spurs off it. In short, a ring must have sockets on it which double up as junctions. I find that hard to believe.

    Wiring my own Ring floodlight

    Is it possible to use a cable to wire a Ring floodlight? In the location i haven't got any wiring, but i can feed it through a window and plug it into a socket on the other side. In America they've got adapters, but in the UK they don't exist it seems. Thanks.

    Balancing Rings, do you?

    Was watching a YouTube video, a US guy singing the praises of the UK plugs and sockets. One of the few drawbacks was about our use of rings and how they have to be carefully balanced. Now, I may have missed this one but, how does one do that? Yes you can design a circuit with even legs and...
