Spur help

[joe68]

Hi all I need to put a new double socket in utility room for a fridge freezer.
The nearest socket I have to the utility room is in the dinning room just opposite the same side wall.
I was planning to spur of that single plug socket, which has 2 wires in this socket.
Will I be a able spur another 2.5mm cable out into a new double socket into the utility room or will need to spur from the single socket into a switched fcu then new wall socket. At the moment I've got fridge/freezer on a 13amp extension lead don't know if extension lead is good enough for the appliance

I also wanted to put a light in garage
Only have a wall socket which has one cable going out from this into a fcu which operates the garage door.
Will I be able to run another 2.5mm cable from the same socket into another switched 3 amp fcu and come out with a 1mm cable into a ceiling rose light

Welcome to the forum...

To give accurate answers we need to know the current protective devices for the circuit, and if its a radial or ring composition..
As you cannot assume what the existing circuit arrangements are just by the number of cables in a socket..

e.g.
A socket with one cable may be the last point in a radial circuit...
Or it may also be a socket spurred off a ring final.

A socket with two cables may be part of a ring final...
Or it may also be a mid-way accessory part way along a radial circuit.

A socket with three cables in may be a branching point on a radial circuit, (one supply in, with two feeds out)...
Or it may also be a branching point for a spur off a ring final, (two ring supplies in, with one feed out).

Basically a bit of continuity testing on the dead circuit is needed to verify its composition and thus what is the best method to extend / amend the circuit.

you are right about the more info needed
as for the number of cables at any one point, the only time it really matters is when its two single sockets on the same spur off a ring final circuit, then you cant add to it unless you make one a FCU,
I would always recommend to fit a twin socket to save any confusion in the future
