Light and socket

[Arsenal2020fc]

just a quick question can I power my outside light from the inside lights direct or do I need to take the feed from the inside to a switched fcu then to the outside. Same question for a outside socket also thanks

You can take a radial off the downstairs ring, into a SFCU (this protects thr cable and gives a local point of isolation if water gets in the fittings), same for an outdoor socket; radial off the ring into a SFCU then on to your socket/light fixture (choose as you want)

Personally I would keep the porch light to a lighting circuit however ensure the circuit has 30ma rcd protection. The socket can be connected direct to the ring final circuit but it needs verifying the socket you connect from is incorporated into the ring final and not a spur itself, again check for 30ma rcd protection.

Sorry to be pedantic, but as your profile says “trainee”…
A single cable from a ring final is a spur.
A radial circuit is a complete circuit from a consumer unit etc, that comprises of a single cable.

Fair cop, meant to put spur, head went for radial.

Once it’s through an SFCU, it becomes by definition, a radial circuit…..
