Electrical help

[markwilliams82]

I'm looking to fit an outdoor plug socket and lights (1 x low voltage wall light)

I am looking to run a cable from a plug socket inside of our house through an existing hole in the wall leftover from a previous Sky installation and fit an IP66 double socket which can then be used for electrical work outside such as mowing the lawn and lights

Would this be ok? Would I need an RCD and what cable would be suitable for outdoor?

Presumably you don't mean to run a cable connected to a plug/socket in the house but rather a cable from the terminals of a socket? For an outside installation you should really take a separate supply from your main board, rather than a spur, which is usually fine for a fixed installation i.e. convector heater for example.

Unless its a very old installation, you should have an RCD on the main board, or at the very least a split board with sockets protected by an RCD. If you don't then you can get an outside socket which has an integral RCD.

If you're running the 230V cable outside then to be compliant it needs to be mechanically protected, so either run it in conduit/trunking or use armoured cable.

You can get an IP66 with built in RCD - I fitted one for my mother off the utility room circuit, though ideally I'd have run a new supply from the board.

Hello,

If you're mounting the socket over the existing hole, then 2.5mm t&e will be fine, and fit a socket with an integral RCD as already suggested. You can spur off the existing socket provided it itself is not a spur.

If you have cable running outside of the house (not just through the wall into the back of an RCD socket) then as already said the supply cable will need to be RCD protected and mechanically protected.

Please remember that twin and earth and white flex (generally) are not UV stable and should not be run outdoors unless in suitable protection (conduit for example)
