Ring Circuit - ready reckoner

[SUNRAY]

There does not seem to be any RCD protection on that ancient Fusebox.
As you should know by now, any new sockets must be protected by a 30mA RCD. So you can’t add a socket, Unless there is an RCD that we cannot see.

Is my small RCD unit getting power from this breaker on the "ancient" CU?
If yes, is that common? I thought that secondary CU usually get powered by splitting at the meter tails: one set for the old and another set for the new consumer unit.

It would appear so.

Define common.

Not necessarily. Whatever works.

What is it for? A shower or garage?

It’s your installation, you should know!

you should get out more. It’s not all done like the way you see it on YouTube.

It's at my property but not my installation. I thought I'd ask since, as you know very well and remind me on every occasion, I am not an expert!

Are you always so patronizing @Taylortwocities or is is just in response to my posts?!

The second small RCD unit was put in during an extension. It powers the new Ring circuit

By your installation I mean an installation that you are responsible for not necessarily one that you installed.

Jupe, sorry to be hard on you but after all the years you’ve been on here - and 3500+ posts - I’d have thought that you’d be able to have the grasp of how to do most of this.

I’ll try not to get involved.

Not a prob.
I appreciate that it may be frustrating from your point of view but this isn't something I do every day or for a living. I am a DIY'er! This inevitably means that I forget and am unsure on things.
I do feel that there is so much I have safely done with electrics off the back of support I have had from this forum.

So - how do you think that might relate to the circuit to which you want to fit the sockets?

It was a tangential question. I wanted to understand how the secondary CU is connected to the main CU.
However, this does mean that I can spur off the Ring that is RCD protected. It will be a faff to get the cables to where I want them...
It also means - as someone suggested - that a new circuit could be added to the RCD unit. I appreciate that this would be notifiable.
