We are installing electrics in a recyling warehouse,its a big building with over 1200 amps supplying,separate dbs.Because of distances to the far end of the buiding,the high bay lights are cabled in 10mm,then of a 25amp mcb.These lights are switched thru contactors,now the emergency lighting around the building are on separate circuits to theses,these are cabled in 2.5mm,ideally when a the local circuit breaks,normally the emer lights will operate,but because of the circumstances of this installation this may not be possible,any ideas,i know merlin gerlin supplies mcbs with aux contacts on them,this may be the only way over it.
