Answer Posted / mojinkoshy
It depends up on the material of the Busbar.
ie. if you use cu bus bar (SWITCH BOARD current RATING / 1.2)= CU. busbar area. if you use Al. bus bar (Switch board current rating/ 0.8) = Al. busbar area.
the bus bar area is normally expressed as 50X6 or 2Nos. 100X12 not like 100sq.mm.
