rcd protected socket

[soulman]

Hi, i need to install an additional socket spurred from the ring, There is no rcd protection on the socket circuit (pme). I would like to install an rcd to protect the whole socket circuit but the board is very old. So i was going to install an rcd protected socket to keep to the regs and keep it simple, but what about the socket i'm spurring from does this need to protected as well. Cheers

only your work

Cheers andy appreciated but what about the cable feeding the spur.

To expand a little on Andys accurate and succinct answer , your cable will also need protecting if you intend to sink it in. If surface in trunking (or whatever), an RCD socket will do.

you installed it so it will need to meet 7671:2008 requirements... so if its chased into a wall, then yes. if its in trunking, then no

 

[soulman]

So if the cable was chased into the wall, the socket i was spurring from and the spurred socket would need to be rcd protected sockets, would this protect the cable?

 

[Andy™]

the existing socket does not need RCD'd. the cable may. the new socket will.

an RCD socket will NOT protect a spur from it

No,

The bit of burried cable and the new socket will need RCD protection,

however you could run the cable in trunking, in correctly bushed metal conduit or use BS8436 cable and the cable wouldn't need RCD protection, but your new socket would

A great help as usual.

Thank you!!!

I'm assuming that this job is domestic??

If the intended load for the new socket is less than 13a then fit an RCD spur next to the donner kebab socket and run new cable from this spur. Thatway it is all rcd protected from the spur to the user.......... :coat

what difference does the earthing system make?

asking a question like that makes me wonder if OP even knows if it is PME or not? .........

Could be TT Rodders

who knows,?

is there a spike outside?

then again, if there is a spike it could be PME, without the fabled spike we will never know.!

Well if it was TT then it'd probably need a RCD regardless whereas TN mightn't
