Certain aspects relate to a bus bar unit for providing three phases of electric current to the windings of the stator of an electric machine while structured to have a compact footprint for fitting within the enclosure of the electric machine. Each winding can have a phase lead end and a neutral end extending above one face of the stator. The bus bar unit can include three phase lead bus bars and a neutral bus bar each having a planar branch with legs extending from the planar branch, each leg having a slot at an end thereof for electrically coupling with either the phase lead or the neutral end of one or more of the windings. The planar branches can be stacked such that they overlap from a top-down perspective but are spaced apart from a side perspective.
