Cabling of equipment at a work site may require lengthy or bulky lines or cables to be run from a power source. A system of cabling control to reduce the length and weight of cables or lines is disclosed. The system uses cable assemblies coupled to work site equipment to facilitate quick and easy coupling and decoupling of cables or lines. The disclosed cabling system may provide for more efficient set up or configuration of a location and operation of work site equipment.

Techniques pertaining to powering multiple platforms with a minimum impact on air passage in a predefined environment are disclosed. Instead of connecting each of the platforms in a chassis to a power supply therein, embodiments of the present invention uses what is referred to as cascading powering to power all platforms within minimum cable delivery. According to one embodiment of the present invention, a motherboard is disposed between two power supply units that are used to power the motherboard. The motherboard has power connectors located towards or near the power supply units so that only short cables are needed to power the platform.

Circuit breakers with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input also include a trip assist spring in communication with the rack gear so that, in operation, the trip assist spring applies a force to the operator slider and forces the handle to a consistent trip position.

The present invention proposes a production support method and system for power control panel production automation, which enable an intention of a designer to be sufficiently reflected on a production site and an error occurred during production to be minimized and, in particular, includes the steps of: realizing, in a virtual environment, a power control panel designed in a 3D type and verifying an error by simulating wiring path information of designed components and electronic units; extracting production data for each process, including component information for each process, component and electronic unit arrangement information, assembly process information, and wiring information, by collecting information distributed to support production automation of the power control panel designed in the 3D type, which has been verified; and automating production by applying the production data to each interworking production facility to support the production automation of the power control panel.

A cooling system for an air insulated switchgear compartment includes: a housing; a fan; and a flap. The fan is mounted to the housing. The flap is mounted to the housing. The flap is positioned adjacent to the fan such that a rotational axis of the fan does not extend through the flap.

A system includes an electrical panel having a high voltage compartment and a low voltage compartment and a first door shiftable between an open position allowing access to the high voltage compartment and a closed position preventing access to the high voltage compartment and a lock shiftable from a locked position to an unlocked position by an actuator in response to a receipt of an unlock signal. A main disconnect switch outside the electrical panel selectively connects a source of electric current to the electrical panel, and a sensor detects a position of the main disconnect switch and sends an unlock signal to the first actuator in response to a detection that the main disconnect switch is in an OFF position.

A neutral bus bar 150 is provided for an electrical distribution apparatus, such as an electrical panel 100. The neutral bus bar includes an elongated body 152 that includes a plurality of wire connectors 154 and plug-on neutral landing sections 156 distributed along a length of the body. Each wire connector includes a side hole 172 and a top landing hole 184 on the body. The top landing hole can receive a hold down screw 176 to secure an electrical wire received in the side hole 172 from a wire-type circuit breaker. Each plug-on neutral landing section is able to receive a plug-on neutral clip from a plug-on neutral type circuit breaker. Adjacent plug-on neutral landing sections have at least one wire connector arranged therebetween on the body. The plug-on neutral landing sections are also distributed with a pitch spacing that corresponds to a pole spacing of circuit breakers connectable on the electrical distribution apparatus.

Provided is an audio device, including: an audio signal communication unit comprising a reception unit configured to receive an audio signal via wireless communication and a transmission unit configured to transmit an audio signal via wireless communication; a plurality of signal input units including the reception unit; an input selection unit configured to select one signal input unit from among the plurality of signal input units; a control unit configured to control switching of the input selection unit; and a signal processing unit, in which the control unit is configured to: switch, when the input selection unit has selected a signal input unit other than the reception unit, the input selection unit to the selected signal input unit and input an audio signal, which is input from the selected signal input unit, into the signal processing unit; and switch, when the reception unit has received an audio signal via wireless communication, the input selection unit from the selected signal input unit to the reception unit and input the received audio signal into the signal processing unit.

The present invention relates to a coupling mechanism capable of pre-coupling an electronic device to an outer casing so that the outer casing and the electronic device are not separated from each other before the electronic device is completely mounted on the outer casing. According to the present disclosure, manufacturing the coupling mechanism for coupling the electronic device with a rigid material may allow the mechanism production cost to be reduced, and allow installation convenience of the device and durability of the mechanism to be improved. Further, improving the structure of the coupling mechanism may allow the electronic device to be installed by only one operator and may shorten the assembly time.
