No extra holes exist in boxes & trays/trunks. Glanding is done by double compression metal glands for armored and screened cables. Gland earthing lug is bolted to panel body by copper tinned bolts. Outgoings trays/trunks are connected to earth bar by Y/G conductor of cross section equal to biggest cable of tray/trunk earthing conductor size All fixing holes are used in mounting Where fixed to structure element, to be done using anchor bolt system. Panels to be fixed to single surface only, to avoid surfaces cracks due to different shrinkage/expansion directions and factors. (either wall or floor fixed) Labeling and identification done following drawings for panel and breakers. Drawings installed inside panels
