Abstract
An enclosure, one input cable and multiple output cables extending through the enclosure, a plurality of circuit breakers and ground-fault circuit interrupters in the enclosure and electrically connected to respective ones of the output cables, and a junction in the enclosure to which the input cable is electrically connected and to which the circuit breakers and ground-fault circuit interrupters are electrically connected. The output cables each include a connector for connection to an electric-powered machine, so that multiple of the machines can be powered and protected by a single power cabinet with a single power-supply connection.
Claims20
A power distribution and protection cabinet for use with a power supply and multiple electric-powered machines, the power cabinet comprising:
- a single outdoor-rated enclosure;
- an input cable that extends through a sealed opening in the single enclosure;
- distribution and protection components comprising:
- a junction that is located inside the single enclosure and to which an internal end of the input cable is electrically connected;
- and
- a plurality of circuit breakers (CBs) and a plurality of ground-fault circuit interrupters (GFCIs) that are located inside the single enclosure and that are electrically connected to the junction, with the CBs and the GFCIs arranged in pairs in series;
- and
- a plurality of output cables each of which is electrically connected to a respective serial pair of the CBs and GFCIs serial pairs at a respective internal end of each of the output cables, extends through a respective sealed opening in the single enclosure, and includes a respective external connector at a respective external end of each of the output cables for electrical connection to a respective one of the machines,
- wherein the single enclosure houses all of the distribution and protection components for operating the multiple machines simultaneously, the single input cable connects to the power supply for delivering power to the multiple machines being used simultaneously, the junction receives power from the single input cable and distributes that power for use by the multiple machines simultaneously, the plurality of CBs and the plurality of GCIs in the single enclosure electrically protect the multiple machines being used simultaneously, and the plurality of output cables deliver the distributed power to the multiple machines.
A three-phase 480 VAC power distribution and protection cabinet for use with a three-phase 480 VAC portable generator and multiple three-phase 480 VAC electric-powered machines, the power cabinet comprising:
- a single outdoor rated enclosure;
- a three-phase 480 VAC input cable that extends through a sealed opening in the single enclosure;
- distribution and protection components comprising:
- a junction that is located inside the single enclosure and to which an internal end of the input cable is electrically connected;
- and
- a plurality of three-phase 480 VAC circuit breakers (CBs) and a plurality of three-phase 480 VAC ground-fault circuit interrupters (GFCIs) that are located inside the single enclosure and that are electrically connected to the junction, with the CBs and the GFCIs arranged in pairs in series;
- a plurality of three-phase 480 VAC output cables each of which is electrically connected to a respective serial pair of the CBs and GFCIs serial pairs at a respective internal end of each of the output cables, extends through a respective sealed opening in the single enclosure, and includes a respective external connector at a respective external end of each of the output cables for electrical connection to a respective one of the machines;
- and
- a portable cart to which the enclosure is mounted, wherein the portable cart includes a plurality of wheels selected for outdoor use on uneven terrain at remote construction and industrial sites,
- wherein the single enclosure houses all of the distribution and protection components for operating the multiple machines simultaneously, the single input cable connects to the portable generator for delivering power to the multiple machines being used simultaneously, the junction receives power from the single input cable and distributes that power for use by the multiple machines simultaneously, the plurality of CBs and the plurality of GCIs in the single enclosure electrically protect the multiple machines being used simultaneously, and the plurality of output cables deliver the distributed power to the multiple machines, and
- wherein each of the output cables has a lower maximum current rating than a maximum current rating of the input cable, the plurality of output cables comprises a number of output cables, and the maximum current rating of each of the output cables is no more than the maximum current rating of the input cable divided by the number of the output cables.
