All incoming & outgoing switches are to be housed in respective compartments hinged and gasket doors at the front. All doors should have panel locking arrangement in such a fashion that it can not be on unless the feeder remains in off position. The rear panel should gasketed wire net guard for ventilation arrangement will be made of easy accessibility to each compartment by providing rear panel doors with locking system . The panel is to be properly gasketed to prevent the dust & vermin. All combination of Horizontal and vertical bus bar chambers is to properly arrange and all electrical equipments are to be fixed by nuts and bolts on suitable Hylam board / porcelain insulators of adequate size and dimension. The outgoing feeder connection from respective switches are to be made at rear side of panel by means of busbar, Aluminium multi core cables/Aluminium Bar, to be terminated on bolted type terminals for cable connection or on bush insulators for bus bar connection. Each compartment will be providing with DMC/FRP board at back side.
