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 part of a ring main. If it has three then it is part of a ring main with a spur and if it only has one then it is a spur.
I spur cannot be added to an existing spur because it would then incorrectly be taken as a socket on the ring main with two cables coming in to it.
A few of the threads ...........It says this is too long and won't let me write any more?
