Abstract:
1. A drawout unit, having a multi-pole disconnect device coupled to a drawout module, for disconnecting and isolating grounded and ungrounded polarities from a direct current (DC) source, the drawout unit comprising: a cradle; the multi-pole disconnect device including an enclosure, a disconnect switch having a plurality of poles each accepting a first polarity of a DC current, the poles being connectable in series, a device input terminal accepting one or more conductors carrying the first polarity of the DC current, and a device output terminal for providing the first polarity of the DC current to a load coupled to the drawout unit; and the drawout module having a housing, a module input terminal accepting a second polarity of the DC current, the second polarity being opposite to the first polarity, a module output terminal for providing the second polarity of the DC current to the load, and a conductor connecting the module input terminal to the module output terminal, where the multi-pole disconnect device and the drawout module are positioned in an abutting relationship in the cradle.
