Ring spurred at origin?

[westward10]

The spur is 4.0 clipped direct so in theory if he uses the same size of cable and installation method as the existing he could add direct to it. Personally I would like to see it on its own circuit.

Ideally I'd like to add more sockets to the circuit in the garage

What are you intending to plug into these sockets.
Is the 32A breaker protected by an RCD?

Yes, protected by RCD. Sockets will be used for drill charging, Henry vacuum cleaner etc.

I would consider it wholly unsatisfactory to have mixed sizes of cable connected in the DB like that. You're practically screaming to get poor connections.

A spur equates to One double or single socket
A One fused or unfused spur unit
A One fusedspur feeding a Fixed appliance.
The only way you can add more than one socket is on a 4mm2 32 or 30 Amp radial circuit if adding more than one the the cable used must be the same as the circuit is wired in 4mm2, this is the same for a 20Radial circuit wired in 2.5mm2
As the circuit in question is a Ring FC adding more than one unfused socket is not allowed

if the CU is in the garage anyway, why not split the tails with \Henley blocks and fit a "garage board". RCD + 2/3 MCBs. then a fault in the garage will not saffect the house CU andyou would have a spare way/s. a 4mm 32A radial for sockets, 6A MCB for lights.....

Thanks.

Based on what's been said, is the following an acceptable way forward?

>Replace the existing twin socket with a fused spur unit, fused at 13 amps.
>Add additional sockets from the fused spur unit fed by 2.5.

This is somewhat unconventional and is clearly ad hoc, yes it should be on its own circuit as I have also suggested but the limitations of what can be added to this spur is clouded by the cable size, 4.0. Appendix 15 which is informative does not demonstrate the use of 4.0 cables/conductors.

Yes .... And it's going to need to be tested
