Putting a spur on an old ring

[pushrod]

If you want to put a spur on a socket that is part of a ring that is connected to an old CU with no rcd protection would it be ok to surface mount inside some mini trunking?
If you are putting just one double socket on the spur does it need to be fused? and if it was two double sockets you would need it to be fused? There's only about 5 double sockets on the whole ring and it has a 32A mcb. cheers.

better to comlpy with regs now cause if the house is ever tested the cu will have to be changed anyway

Surely only if the client requires the installation to be 17th compliant after all you have no legal right to force compliance of an older installation.

I have a fused spur connected directly to the consumer unit. That fused spur feeds two double 13A socket outlets and one single 13A socket outlet. Is this legal? What is the limit to the number of socket outlets that may be connected to a fused spur?

Many yhrnks

In itself there`s nothing wrong with spurring off a Ring Final Circuit at the Consumer Unit. If it`s via an FCU then it may supply an indefinate number of socket outlets, as that entire spur is protected by the 13amp fuse. So, if the total loading on that spur is assessed as being unlikely to draw more than 13 amps then AOK. It could even be wired in 1.5mm T&E. Still ok in theory. However, depending on the anticipated use, the installer possibly could be fairly accused of poor design, but not unsafe work.
