I have built an extension which incorperates a seperate'granny' flat. I have wired the lighting and mains circuit and now wish to connect it all up at the consumer unit.
My intention is to connect this consumer unit to the original house consumer unit using armoured cable (twin cored) It will be travelling 40 m or so in loft space to my Granny flat CU. What size cable will I have to use. I have been loosely advisewd to use 25mm is this correct?
The armoured cable on arriving to the Granny flat CU will go via a mains on/off switch (any special size or style?) Then via a sub meter, then into a consumer unit. Is this correct? I intend to use a standard Cu from screwfix or similar.
I will NOT be connecting the armoured cable to the original house as I guess this raises other complications
Thanks!
