Modular power distribution system

A central DC office power system comprising:

• a modular power bay comprising a plurality of rectifiers each being rated at up to 450 amperes of direct current for converting the alternating current to direct current, the direct current being at least about 15,000 amperes or less, a power bay charge bus in electrical communication with said rectifiers for receiving the direct current from the rectifiers, said power bay charge bus having opposing ends;
• and a frame being no more than about seven feet in height for containing said rectifiers and said power bay charge bus;
• wherein said power bay charge bus is disposed within said frame;
• a modular power distribution assembly comprising a plurality of electrical fuses or circuit breakers each being rated at about 200 to about 600 amperes of direct current for routing direct current therethrough;
• a power distribution charge bus having opposed ends wherein one end of said power bay charge bus is in electrical communication with one end of said power distribution charge bus, said power distribution charge bus being in electrical communication with said fuses or said circuit breakers via a shunt interference;
• a frame being no more than about seven feet in height for containing said fuses or said circuit breakers and said power distribution charge bus;
• wherein said power distribution charge bus is disposed within said frame;
• wherein when said modular power distribution assembly and said power bay are adjacent to one and the other, one end of said power bay charge bus being interconnected with one end of said power distribution charge bus to provide electrical connection therethrough;
• a battery reserve in electrical communication with said power bay charge bus for delivering supplemental DC current;
• a battery distribution fuse bay in electrical communication with said power distribution assembly for delivering a plurality of DC currents to DC power-consuming equipment.

A power distribution assembly capable of receiving and delivering about 15,000 amperes or less of direct current comprising:

• a frame having a base member, an opposed top member and plurality of vertical posts disposed therebetween to define a generally rectangular structure, two of said vertical posts defining a front surface of said power distribution assembly;
• devices for monitoring the direct current, said devices being disposed on said front portion;
• a plurality of fuses or circuit breakers contained within said frame;
• said fuses or said circuit breakers being in electrical communication with a charge bus for receiving the direct current and having fuse or circuit breaker outlets that are angled towards the first surface for delivering the direct current;
• a plurality of cables having fuse or circuit breaker-connecting ends;
• a tray for supporting portions of said electrical cables at said fuse or circuit breaker-connecting ends, said tray being angled towards said first surface;
• wherein said angled fuse or circuit breaker outlets and said fuse or circuit breaker-connecting ends are terminated at an opening of said front surface.
