Similarly, can you spur off an outside socket? if the existin g socket is on the ring, then you can spur off 1 socket without a FCU. if it's on a radial 16A cct. you can just add your otside socket. only if the existing socket is itself spurred off a ring do you need to fit a FCU.
In this way, can you put a socket on a lighting circuit?
Putting a 13A socket on a lighting circuit is not expicilty prohibited. However there are a couple of things to bear in mind. Lighting circuits are normally on a 6A breaker, plugging in a large appliance my trip the breaker. Sockets intended for general use with a current rating must be RCD protected.
Can I run a spur off a socket?
The easiest way of connecting into a ring circuit is to run a spur cable from the terminals of an existing socket – but you can't connect it to any socket. The IEE Wiring Regulations are very specific about this. You mustn't run a spur from a socket that's already on a spur, or that already supplies a spur.
