Spur off a spur question

[Mad Maximus]

I know I need to install a 13amp fuse before the first spur before I can add another spur from it but does installing this negate the separate fuse or is this not allowed? Many thanks.

If you want to run multiple sockets on a spur you need the cable appropriately protected as you’re effectively branching a radial off a ring.

What you’ve pictured is intended to protect the devices plugged into it, not the infrastructure itself. FCU would be the normal solution.

You add a fused spur first and then additional sockets after that, If your existing socket circuit is already Rcd protected you wont need one of those.
I cant answer how many sockets are allowed after the spur but I don`t think there is a limit as they can only pull 13 amps in theory.

That only protects against earth leakage from what’s plugged into it.

It has no over current protection at all, so you need a fuse or MCB to protect the spur

Sorry didn’t understand the difference between what I pictured but now I do. So I need the below first which I understand but has anyone found a double faceplate version that does the same job?

The idea is you put one of those next to an existing socket first so you would need to chop in a new single backbox or use a surface mount one if your not bothered.
You wire it from the existing socket then from there on to the new ones.
Dont mean to sound rude but if your struggling then get a spark in.

Not done a spur from a spur before so just wanted to double check. The cables leading to the existing spur are rather short so I may have to go back to the original connection to put some longer cables in so I can use a single plate fcu then connect the two spurs I need. If there was a double plate fcu it would make life easier.

By the by if everyone suggested getting a trade in everytime someone asks a question in a subject they are not 100% familiar with there would be a lot more bodge jobs as most people would just have a go.

You can make one up with a grid system, a fuse holder and three blanks https://www.screwfix.com/c/electrical-lighting/fus...

It's the original spur which needs to be fused, when you add another spur to it.
So the total going into the original spur cannot exceed the cable rating.

So you need to add the fuse somewhere between the ring main and the first socket on the spur.

It may be easier to extend the ring, so the original spur is part of the ring, then you can take a spur from it.

Or just get an extension lead from Asda.
