Mate of mine is using the following on his NICEIC DI assessment.
Instead of running a sub from the house cu at the front of the mid-terraced (I advised up the front of house into loft & drop down the back of house) he (because of cost its a mates rates job) has extended the house only ring final circuit down the garden 10mtrs to garage terminating into a cu via insulated adaptable box.
New cu set up as TT with 30mA rcd mainswitch & new lighting circuit 6amp + 3x sockets 16amp.
I said I wouldnt be happy to use it as an assessment peice myself.
