Two radials from one 20A mcb

[Matesrates]

I have been asked to add a double socket in or right next to the board cupboard.
There is no spare ways and the house sockets are wired as two radials.
There is however a circuit for an electric fire wired in 2.5 T+E from a 20a mcb, i was under the impression there is only to be one cable/circuit per mcb apart from ring circuits.
Can i wire this new socket from this mcb? The socket will only be used for a hoover and maybe a table lamp.

Thanks

You have been misguided on this.

Why are you under this impression? What does your regulations book say on the subject?

Why not connect the new socket to a socket circuit rather than a heater circuit, or is that too logical?

To add to the previous posts, what is the rating of the electric heater out of interest?

just spur off socket radial in cu.

There is obviously a limit to the number of conductors you can get in the top of an MCB, it would be bad practise to cram too many in, I although technically acceptable I personally wouldn't want to get any more than three radials on one MCB as it would be a much better idea to change the board or some other solution as you would be adding too many circuits to the cu than it's designed for as remember usually you have matching numbers of terminals for earth and neutral and you don't want too many crammed in there.

not only this, it could easily add to confusion for the next spark who looks at it not know lung exactly which conductor relates to which circuit.

You can't get more than one radial into an mcb! No matter how many seperate conductors you put in there it will still only be one circuit.

Still one circuit, and with 20amp radial its UN limited,god I hate that.

I thought that would be the case. Someone told me that as an apprentice and it just stuck in my head for whatever reason. Thanks for the helpful replies

Have I missed something whilst I was out?

Surely we deserve to know the topic of 2 members relating posts that have been deleted?

Your statement is contradicting Dave and as is the usual seemingly awkward, can you expand?

simple answer to your first question is.

you can have 1 spur per point on a ring, i would only have 1/2 spurs from the board if it was a 20a radial but my preference should be to reroute a leg to the new socket and put a new leg into board

I don't see anything wrong with my first post in this thread, call it a spur or whatever you want, but if you have two radials with say a dousen sockets on each, they ate two circuits in my mind.

I can't see anything wrong with your first post, maybe Dave being awkward (first for everything)

Cant see why shanksy has quoted me?

Sorry shanky
