Redundant power delivery

A redundant power delivery system, the method comprising:

• a power cable comprising a first plug including contacts for hot, neutral, and ground and a plurality of power lines, each power line electrically connected independently to the hot, neutral, and ground contacts of the first plug at a first end and each power line having a second plug at a second end providing contacts for hot, neutral, and ground;
• a redundant power adapter comprising a plurality of input connectors, each input connector comprising a hot, neutral, and ground contact and adapted to engage each second plug of each power line,
• the redundant power adapter further comprising a plurality of output connectors, each output connector providing a hot, neutral, and ground contacts and adapted to engage a plurality of input connectors of one or more redundant power supply receptacles, each input connector of the redundant power supply receptacle having contacts for hot, neutral, and ground;
• the redundant power supply receptacle further comprising a switch to select one or more of the input connectors of the redundant power supply receptacle for receiving power.

A method of redundant power delivery, the method comprising:

• receiving power from a single power source over a power cable, the power cable comprising a first plug including contacts for hot, neutral, and ground and a plurality of power lines, each power line electrically connected independently to the hot, neutral, and ground contacts of the first plug at a first end and each power line having a second plug at a second end providing contacts for hot, neutral, and ground;
• each second plug of each power line is coupled to an input connector of a selectable redundant power adapter, each input connector of the selectable redundant power adapter comprising a hot, neutral, and ground contact and adapted to engage each second plug of each power line;
• the redundant power adapter further comprising a plurality of output connectors, each output connector providing a hot, neutral, and ground contacts and adapted to engage a plurality of input connectors of one or more redundant power supply receptacles, each input connector of the redundant power supply receptacle having contacts for hot, neutral, and ground;
• the redundant power supply receptacle further comprising a switch to select one or more of the input connectors of the redundant power supply receptacle for receiving power;
• and
• selecting for use, by the switch, the power from one of the plurality of independent power lines.

An apparatus for redundant power delivery, the method comprising:

• means for receiving power from a single power source over power cable, the power cable comprising a first plug including contacts for hot, neutral, and ground and a plurality of power lines, each power line electrically connected independently to the hot, neutral, and ground contacts of the first plug at a first end and each power line having a second plug at a second end providing contacts for hot, neutral, and ground;
• each second plug of each power line is coupled to an input connector of a selectable redundant power adapter, each input connector of the selectable redundant power adapter comprising a hot, neutral, and ground contact and adapted to engage each second plug of each power line;
• the redundant power adapter further comprising a plurality of output connectors, each output connector providing a hot, neutral, and ground contacts and adapted to engage a plurality of input connectors of one or more redundant power supply receptacles, each input connector of the redundant power supply receptacle having contacts for hot, neutral, and ground;
• the redundant power supply receptacle further comprising a switch to select one or more of the input connectors of the redundant power supply receptacle for receiving power;
• and
• means for selecting for use, by the switch, the power from one of the plurality of independent power lines.
