[QUOTE="Jimbo6871, post: 540698, member: 34647"] That is a fair point and not dissimilar to what my original spec was..... howeverrrrrr...... Landlord has all the sub lines first fixed in 6mm T&E, ground floor in metal trunking, 1st floor clipped through roofspace. (I spec'd all subs in SWA - LL didn't like the price, went to Bodge-it & Leg-it who have since been told to clear off - another horror story for another day). So, as far as I can make out since the drops to the subs are T&E, they need RCD protection at the main DB (at least for the first floor), although I'll happily stand corrected if it can be done with MCB's as discrimination is non existent with two 30ma trips in series, so yes a recipe for a lot of nuisance tripping call outs and general tenant unhappiness - the LL has already been warned.
