I have been asked to price for a db change in a flat above a veterinary centre that the nurses on call stay in. The supply to the whole building is a TN-S 2 phase. It has a 16mm main earth conductor, 25mm tails and 10mm's to services.
The flat above is supplied with a piece of 16mm T&E on a 60A switch fuse on a seperate credit meter to a wylex re-wirable board. Is the 6mm cpc in the 16mm T&E allowed if it is ok with the adiabatic equation? or does it have to be upgraded to 16mm for me to be allowed to fit the new db? As usual to route a new cpc is a pig of a job!
Any help much appreciated
