I am installing some low voltage lighting in my bathroom. However installing the new lights on the existing lighting circuit would potentially exceed the 1200w limit.
I have recently removed an electric shower and the circuit for this is now redundant. If I were to replace the 20 Amp fuse for this circuit with a 5 amp fuse in the consumer unit can I then use this as a new lighting circuit? Or is the 2.5mm cable unsuitable and will I have to have an electrician fit a new lighting circuit for me with new 1mm cabling?
