A spur is a branch from a ring (or radial) just like on a train track really.

If it is plugged in we do not usually call it a spur.

Some people (wrongly) call a fused connection unit (FCU) or a switched fused connection unit (SFCU) as spur or switched spur because traditionally they were often used on a ring to fuse a spur down. Spurs maybe fused or unfused.

I mentioned caveats - I wanted to give you a simple answer so I did that - But you need to consider the type of cable you are running, its route and mechanical protection (including protection from water ingress). What is the total likely load that you are running. Thereby what are the problems, there may be some.

So your basic idea can be done but you need to take somethings into account
