Hi all,

new to this forum. 

Question: Taking a spur off a socket through the back of the socket into another room. 

Socket 12 inches off the ground. Is it better to run armoured cable to new socket as it will be running across a floor. (Lot of ripping and plastering otherwise)

Or, put a pipe in?

What radius can you bend armoured cable 90 degrees?

Across the floor or in a groove cut for it? Best is to put 20mm conduit through then you can pull individual 2.5mm cables in. The radius depends on how big for a 13A spur probably 40mm in SWA @ 2.5mm. Are you extending the ring or running a spur - you will need to approach them differently from a wiring regs point of view. With a spur I would fit a switched fuse local to the socket the cable is coming from on the ring, although not a requirement - you do have to match the current capacity of the protection device on the ring with the cable and 2.5mm SWA is rated at 36A or there abouts, its just another layer of protection as you don't have the two way loop of the ring to handle sudden high currents when someone later wires a whole load of other sockets of the one you are fitting!

Or even worse. Hacks into a ring. Sticks on a few new sockets, and then joins it back into the ring........Nothing wrong with that.....Except that 4 times in the last 5 years i have found that done, and joined into another ring.  !!!!!!!!!
