My small bungalow has a ring main wired with 2.5mm cable. But it is not 100% wired as a ring circuit; not all of the sockets have two cables connected. Some are conected to a single 2.5mm cable going to a junction box on the ring (i.e., they are spurs). Does this mean the circuit should have a fuse of no more than 20 amps?
If so, is there any point in it being a ring circuit at all? Could the person who wired it up have saved several yards of 2.5mm cable and just made the whole circuit as several spurs coming from a 2.5mm feed with a 20amp fuse?
In the kitchen, there are two double sockets above the worktop. These are fed by just one 2.5mm spur. Is this OK considering that a nicrowave, a kettle and a toaster might be fed simultaneously from these sockets?
Thank you,
Jake
