For low-voltage switchgear assemblies, different model specification, working conditions and basic structure, as wel as differ-ent material, dimensions and instal ation of busbar, affects the selection of busbar. On the premise of ensuring safety perfor-mance and utilization life of assemblies, the investment wil be reduced by reasonable selection of busbar cross-sectional area. It introduces the main factors affecting the selection of busbar of low-voltage switchgear assemblies, describes the common method of busbar selection, national standard requirements for busbar, and Schneider and ABB requirements for busbar cross-sectional area of the switchgear assemblies. It analyses the problems on the common method of busbar selection. Final y it presents the recommended methods on busbar selection in electric engineering design.
