Abstract

Aspects of the invention are directed to power distribution systems and methods for distributing power from a primary power source and a backup power source to a load. In one particular aspect, a power distribution system includes a first input to receive input power from the primary power source, a second input to receive input power from the backup power source, an output that provides output power from at least one of the primary power source and the backup power source, a first switch operatively coupled to the first input and the output and operative to selectively couple the first input to the output, a second switch operatively coupled to the second input and the output and operative to selectively couple the second input to the output, and a controller operatively coupled to the first switch and to the second switch and configured to control the first switch and the second switch to provide an electrical interlock.

Claims

1. A method of installing a power distribution system in a facility, the method comprising:

mounting an electronic enclosure to a wall in the facility;

installing power distribution cables in the enclosure, at least one of the power distribution cables being coupled to a primary source of power, and at least one of the power distribution cables being coupled to a secondary source of power; and

installing a panel having electronic components in the electronic enclosure by rolling the panel across the floor of the facility and into the enclosure using at least one wheel mounted on a bottom portion of the panel and at least one handle mounted to a top portion of the panel;

wherein installing a panel includes aligning the panel with mounting hardware attached to a back wall of the enclosure and mounting the panel, including the at least one wheel, to the back wall of the enclosure.

2. The method of claim 1, further comprising electrically coupling the power distribution cables to the panel.

3. The method of claim 1, further comprising selecting one of the primary source of power and the secondary source of power as an output power source for the power distribution system.

4. The method of claim 1, further comprising coupling at least one data cable to the panel.

5. A method of installing a power distribution system in a facility, the method comprising:

mounting an electronic enclosure to a wall in the facility;

installing power distribution cables in the enclosure, at least one of the power distribution cables being coupled to a primary source of power, and at least one of the power distribution cables being coupled to a secondary source of power;

installing a panel having electronic components in the electronic enclosure by rolling the panel across the floor of the facility and into the enclosure using at least one wheel mounted on a bottom portion of the panel and at least one handle mounted to a top portion of the panel, and attaching the panel to a back wall of the enclosure using hardware attached to the back wall of the enclosure; and

after installing the panel in the enclosure, removing the at least one wheel and the at least one handle from the panel.
