Final Field Fit Program Pow-R-Way III Low Voltage Busway The Exact Fit the First Time Eaton is dedicated to producing a quality product and delivering it on time. The Final Field Fit Program was established to effectively manage the dimensional uncertainties that are often inherent in busway layouts. This program has been successful for many years and it provides the assurance of an exact fit the first time. It allows for busway runs to be released for manufacture when certain dimensions are not yet determined. It also eliminates the costly delays that can occur when sections have to be remade in order to accommodate last-minute job site changes in routing. Benefits include: Exact fit the first time Eliminates incorrect pieces Facilitates on-time project completion

1. Customer Faxes Dimensions for F01 Final Field Fit piece shipped within 5 to 10 working days. 2. Details on Process Greenwood provides this information for customer reference: Drawing number Order number Phone number Fax number Customer must fill in this information before faxing to Greenwood: Final field fit piece dimension. Shipping information: Name Company name Phone number Fax number Date Other field fit items Requested shipping date What is a Final Fit Piece? A field fit section of busway is typically an elbow or a short section of feeder that is intentionally left out of a run for later shipment. It is most often a mutually agreed upon section between the customer and the plant. In Figure 1, the field fit piece is identified as item F01, a downward elbow flange. Upon release of the order, this item is kept on hold for field measurement. The contractor will install the busway (items A01 through A12) and is then able to obtain an exact dimension for the final field fit piece. In this case, the measurement for item F01 should be made from the top of SWGR 1 up to the outside edge of the busway (dimension A ) and from the outside edge of the busway back to the edge of the housing of item A12 (dimension B ). When Should the Program Be Used? If you are uncertain of the exact dimensions on long runs or if you have pathway obstructions that will require job site routing of the busway, this program can help you. Here s How the Final Field Fit Program Works 1. Review busway requirements with your Greenwood product engineer. Together, you can determine which piece should be field fit. Release all the busway except the field fit piece. (There is a limit to the number of field fit pieces that can be supplied, so please consult your Greenwood product engineer.) 2. The contractor installs the busway and measures the field fit piece dimensions. 3. The contractor can fax the dimensions directly to the Greenwood product engineer on the Final Field Fit Program Fax Sheet Figure 2. The contractor simply fills in the requested information and transmits the form. The Final Field Fit Fax Release Form is customized to each order and shipped to the job site with the busway. The field fit items will match the F items shown on the construction drawings provided by Eaton. It will also reference the Cutler- Hammer drawing number and General Order number. 4. The field fit piece will ship within 5 to 10 working days after receipt. Offset and combination offset fittings may take longer to ship. Also, if more than 5 field fit pieces release at the same time, the shipment lead-time may take longer than 5 to 10 working days. Contact the factory for lead-times. 1 2 A = B = Edge of Housing A12 (13 Min) B C L BUS T F01 A11 2 0 Final Field Fit Program Fax Release! Fax Direct to Greenwood factory. Ref.

Pow-R-Way III Busway Feeder and plug-in indoor busway with copper conductors are available in 10-feet (3.0 m) and 6-feet (1.8 m) lengths. They can be used interchangeably without the use of special adapters or special splice plates, provided they are the same current and system rating. Pow-R-Way III is constructed with a lightweight and rugged, two-piece all-aluminum extruded housing, which is rated as a 50% ground path. Copper bus bars for plug-in applications have full-sized conductor tabs welded to their side edges to form the plug-in contact surfaces. Tabs are the same exact thickness as the conductors and are fully rated up to 800 amperes. Corner Joint Elbows When it comes to bends and turns in a bus run, the Pow-R- Way III corner joint is the most compact elbow in the industry. Given the complexity of today s industrial and commercial distribution systems, and the need to coordinate layouts with HVAC, plumbing and lighting requirements, space quickly becomes a critical factor. The Pow-R-Way III corner joint elbow can be installed in areas where traditional 90-degree elbows could never have been accomplished before. Due to its compact design, the corner joint also allows for layouts that provide optimum utilization of space. Critical section length that would normally be required for a traditional elbow leg length can now be dedicated to maximizing usable plug-in section length. The corner joint is as reliable as traditional elbows. It is seismically certified and exceeds the requirements of both the UBC and CBC (Zone 4). The corner joint is UL listed for indoor applications. Fittings and Accessories End cable tap boxes are available for all ratings in the Express Bus program. Plug-in cable tap boxes are also available and are listed in Catalog CA08101001E, Section 17. One horizontal hanger will be included for every 10 feet (3.0 m) of busway.

Busway Value Calculator Pow-R-Way III Low Voltage Busway The Advantages of Busway There are many definite advantages to busway over cable and conduit distribution systems: Less Man-hours for Installation Busway is engineered and built to fit your specific layout needs. It is shipped to the job site ready for installation. Busway can be installed quickly and efficiently with only 40% of the labor required to install a conduit and wire system. Compact Size Due to its sandwich style design, busway has a very compact cross-sectional area and therefore occupies far less space than multiple conduits. Reusable, Expandable, Flexible As distribution needs change, you can easily relocate existing busway runs or add new sections to extend bus runs into other areas of your facility. A Safe and Versatile Design Pow-R-Way III meets the requirements of UL, NEMA, CSA and IEEE. Additionally, Pow-R-Way III is seismically qualified to both the UBC and CBC, exceeding Zone 4 worst case levels. The conductor bars are totally enclosed in a nonventilated aluminum housing which provides the highest short circuit ratings in the industry today. All bus plugs are polarized to prevent improper installation and the plug-in outlets are rated as IP2X for finger safety to IEC 529. Lower Installed Cost The savings in labor can generate a total installed cost reduction of as much as 40% compared to a conduit and cable installation.

Busway Saves Time and Money Myth Busway is more expensive than cable and conduit. Fact With the higher wholesale costs of cable and conduit, busway is very competitive when comparing material costs. However, it is the reduction in the number of man-hours required for installation that provides a significantly lower installed cost with busway than with pipe and wire. Myth Busway requires accurate layout and measurements. That takes too much time and effort and leaves room for errors. Fact Accurate layouts can be done quickly with the help of Eaton s Cutler-Hammer Greenwood plant. Customer approval drawings are mailed 2 weeks after receipt of the order. The Final Field Fit Program provides the means to effectively manage the dimensional uncertainties that are often inherent in busway layouts. The savings realized with a busway installation should compensate for the time and effort required. Myth In the low to mid-range (225 1600 ampere) ratings, there are no savings. Fact Busway can be competitive at any rating. A number of variables determine the installed cost of a distribution system. Contact Eaton for application assistance. Evaluating a Comparison When you evaluate your own job comparison, try an aluminum or copper busway alternate against copper cable. As you can see from the table above, aluminum and copper busway required approximately 1/3 of the installation time. Pow-R-Way III has many features that are beneficial, such as Class B insulation, an integral housing ground, an isolated ground option and a 200% neutral option.

Determine a Cost- Effective Solution The Busway Value Calculator has been developed to help customers determine if Cutler-Hammer Pow-R-Way III Busway or cable and conduit is the most cost-effective solution for any given application. This user-friendly tool does a side-by-side total installed cost comparison between busway and cable and conduit. With the lightweight, compact design of Pow-R-Way III Busway, there are significant labor cost savings resulting in an overall installed cost savings over cable and conduit systems. How It Works The Busway Value Calculator utilizes the NECA labor unit system to help calculate the labor costs associated with installing cable and conduit systems as well as busway systems. There are no hidden tricks and the user has full control of the comparison. While default pricing is included, all data, from the NECA labor unit values to material costs, can be adjusted to match your costs and efficiencies. This also allows you to see cost impacts as different variables change. Based upon your fully burdened labor rate and material costs, the calculator configures a material cost comparison, labor cost comparison and a total cost comparison as well as bills of material for both. Most selections may be made via drop-down menus. Once the ampere rating of the system is selected, the Busway Value Calculator automatically sizes the conduit and cable and determines the number of each per phase. This is done per NEC guidelines and tables. This may also be done manually within the program. The final comparison results may be printed in a report format or exported as a Word document and saved. Listed below is a cost comparison for a 1600 ampere tie run between two switchboards. The bill of material is for 300 feet, 3-phase, 4-wire with ground, eight elbows and two switchboard connections. Rigid conduit is used with 500 kcmil THHN copper cable. The fully burdened labor rate is set at $35.00 per hour.

Additional Comparisons In addition to the installed cost comparison, the Busway Value Calculator does a space savings comparison and voltage drop comparison between busway and cable and conduit systems. Space Savings With the compact design of the Pow-R-Way III Busway, it occupies far less space than that of multiple conduits. In the sample comparison shown, conduit would occupy 92 square inches of space along the run compared to only 32 square inches for Pow-R-Way III Busway. Voltage Drop Efficiencies With Pow-R-Way III Busway only having one or two conductors per phase and the Pow-R-Bridge joint design, its voltage drop is much lower than that associated with cable.
