I'm hoping to create a new socket in my internal garage by creating a spur from the existing socket which has existed since day 1 of my 2014 property. I've been following my trusty 2006 DK DIY book and it suggests that i must first check if the socket is on a ring main circuit or is the intermediate outlet on a two outlet spur.
The existing socket is part of the downstairs circuit breaker which I can isolate along with the other downstairs sockets. The socket has 2 cables in it and as i don't have any technical equipment, the book suggests that I test the circuit type by disconnecting the 2 live cores, separate them and then checking the other downstairs sockets. The book says that if the socket is on the main circuit all other downstairs sockets should be dead. When I do this though, all other downstairs sockets continue to work. Is the book right, should I be concerned and can I still run a spur from this socket?
