1 Switchboards Product Overview A switchboard distributes large electrical current used by electrical equipment and building requirements. Applications can range from a small office building to a major industrial complex. Switchboards are generally accessible from the rear as well as from the front and are not intended to be installed in cabinets but rather free standing on a poured cement slab. Commercial metering switchboards provide electrical system distribution and metering for commercial applications. Using standard Pow-R-Line C construction, these switchboards incorporate metering sections with tenant feeder circuits. Pow-R-Line C Distribution Switchboards combine a space-saving design with modular construction and increased systems rating to provide economical and dependable electrical system distribution and protection. Pow-R-Line I Switchboards are engineered in a new compartmentalized design for applications where greater safety is required. A variety of configurations are possible including utility metering, customer metering, and main devices. Integrated Facility Switchboards use the Pow-R- Line C group mounted switchboard design to integrate separate electrical distribution and control equipment into a single factory assembled and connected package. Eaton s innovative IFS incorporates advanced Eaton electrical distribution equipment, including Pow-R-Command, Smart Breakers, and building automation into one spacesaving structure; therefore reducing installation time and man-power needed. Wall Mounted IFS provides electrical control, monitoring, and power quality while providing valuable square footage savings. For more information and panelboard descriptions and specifications, refer to the Distribution Catalog. Or,

IFS Distribution Structures Integrated Facility Switchboards (IFS) use the Pow-R-Line C switchboard design to integrate traditionally separate electrical distribution and control equipment into a single space-saving factory assembled and connected package. The service entrance equipment can be integrated with multiple lighting and appliance branch panelboards into a compact front accessible group mounted switchboard. Where multiple panelboards are used in the same electrical room as a conventional distribution switchboard or power panelboards, the integrated design will significantly reduce equipment space requirements as well as reduce installation time and costs. Other associated equipment can also be integrated into the assembly, including dry-type transformers, time clock space, lighting control, electronic controls, surge protection, customer metering and energy monitoring devices. Depending upon the application, other user defined equipment such as a subsystem control package may also be incorporated. Adding an IFS Structure 1. Select an IFS compartment from the IFS Distribution Structure bar in the parts bin. 2. Click on the compartment structure in the layout to display the optional equipment in the parts bin. 3. Double-click the option from the parts bin and complete the characteristics for that item in the window that is displayed.
