An improved power distribution unit substation, having a plurality of differing voltage rated main breaker cells, encased within a single housing is disclosed. The improved power distribution substation saves considerable floor space as compared to prior art substations. One embodiment houses a plurality of main breaker cells in a single housing. In this embodiment, a low voltage main breaker cell is vertically positioned above a plurality of medium voltage main breaker cells. Alternatively, a medium voltage main breaker cell is vertically positioned above a plurality of low or medium voltage cells. Improved single-ended and double-ended power distribution substations are disclosed that offer cost and floor space savings as compared to prior art substations.
