Would it be ok to have 4 S/O wired in 2.5mm T&E ring main and supllied by a 16A MCB? It would be 3 S/O in new sunroom and 1 outside S/O. It just seems alot to use a 32A MCB to supply only 4 S/O which would use minimual amount of power, prob TV an lamp.
Toasty - 16amp radials are outdated. It's 20amp for 2.5mm radials.
A sunroom will often end up having a heater......when the sun has gone.
A 32amp 4mm radial would be easier......or just bung a ring in.
Odd that you are happy to install a ring, and then deliberately put a 16amp breaker on it?? Whats the point?? Do you think you will be saving electric or something
