    Can I add another socket to a ring main using 2 debox in line connectors? Cutting the cable inbetween socket A and socket B on a ring main adding 2 debox in line connector boxes on the cut ends of the cable and running new cable to new socket C? Is there any further insulation to put over the boxes or any measures to take to ensure they are secure? Or is there something better to use?

    Iv'e never use debox. But looking at it, it is made as a simple connector, so you are ok for two cables but, I guess, you want to have more than two?

    In any case, if the Debox is going to be hidden/not accessible it is not suitable becasue it has screw terminals. You'd be better using Wago connectors in a proper Wago box. Or even one of these https://www.screwfix.com/p/debox-4-...d=411904#product_additional_details_container

    Why not run the new socket as a spur from the nearest socket on the ring? The fewer connections you need to make the better.

    As mentioned above, you need to use screwless maintenance-free connections/boxes.

    Either of these:

    Yes that's probablt sensible isn't it. I'd been told it's better to have it on the ring main if possible? Because spurs shouldn't be overloaded or something?

    What are you planning on plugging into the extra sockets?

    Thanks yeah it's under easily removable boards by the socket but I'm getting the impression still needs to be maintenance free boxes really.... But there's nothing wrong in principle with putting these 2 connectors under boards to install another socket if they're maintaince free boxes?

    Spur would be fine. if you start to have lots of high power appliances like heaters etc. from the spur and ring socket that may be a problem.
    16A per leg on the ring as you would be using 2.

    Okay starting to make more sense.

    But I couldn't use 16a rated connector if it was a spur?

    You wouldn't need to use a connector for the spur. Just wire the spur socket cable from the existing socket's terminals. If there is a risk of overloading the spur, fit an FCU inbetween:
