Title Block features: Title block features include borders, footerblocks, a revision block, and a title block. You see these features inthe drawing space and on your printout.

Toolbar: A dockable bar displayed just below the menu barcontaining command buttons that offer quick access to several of thefunctions found in the menu bar.

Creating a Drawing—Overview This section provides a template for creating a one-line drawing in Pow-R-Designer. Ifyou are a first-time user of this program, you may find the typical approach outlinedbelow useful. The order of the following steps and the details of their contents serve asguidelines only; you will eventually develop your own approach. Many projects requiretheir own order of events as well.

1. Create name for file 9. Join products to busway 2. Select printout size 10. Move, copy, or delete 3. Dock toolbars 11. Find (search for) a product 4. Place utility entrance 12. Change font 5. Place other products 13. Perform calculations 6. Join products with cable/busway 14. Prepare schedule 7. Create busway 15. Export spec guide 8. Perform product selection 16. Export drawing to CAD

These steps are briefly explained below:

1. Create a file name: Click onFile on the menu bar, then on SaveAs. At the Save As dialog box, clickon the drive and folder where youwant the drawing file to reside, thentype a name in the field File Name.Click on the Save button. Thisprocedure not only names your work, but also establishes a file and pathfor it. Save frequently as you work to mitigate data loss due toelectrical outages, software conflicts, or computer failures. Note: Youcan also display the Save As dialog box by clicking on the Save button if

your current drawing has not yet been saved. Hot keys = Alt F, A. SeeSave and Save As sections in Chapter 2. 2. Select a size for your printout: This printout size control is to theleft of and just above the drawing space. Size A, the default size,provides the smallest of five printout sizes available. Size E is thelargest—here you can place the greatest number of products. Click onthe drawing-size down arrow and scroll to find the size you want.These sizes correspond to traditional draftsman’s standards: A = 8½ 511", B = 11 5 17", C = 17 5 22", D = 22 5 34, and E = 34 5 44".This size can be changed any time during your work. Note: Changesare not apparent onscreen as you switch from one size to another.However, you can see a change in the size of the scroll-bar sliders asyou use this function. 3. Move and dock the toolbar and/or the parts bin: If you prefer toplace a button group (toolbar or parts bin) in another area of the defaultwindow, press and drag on the border of this group. You not only canrelocate the assembly to another part of your screen, but you can alsoreshape it in various ways as you continue to drag on its border. Thesearrangements are preserved when you save your drawing and are foundin the same position when you access that drawing again in the future. 4. Configure and place the utility entrance:∗∗ Depending on the job,the utility entrance is generally where you begin a drawing. Click on theUtility Entrance button, move the pointer to the drawing space, thenclick again. Complete the fields in the displayed Service Entrance dialogbox, then click on OK. The service symbol appears in your drawing.See also the Utility Entrance section in Chapter 4. 5. Configure and place other products:\\ The parts bin is designedso that the user can place products in the drawing from the left side ofthe (default) parts bin first. Products on the right side of the parts binare likely placed later, typically speaking. Place a product by clicking ona parts bin button, clicking on the desired location in the drawing, then

∗ To alter specifications for any product, double-click on that product in your drawing. Doing sodisplays its dialog box, where you can make the revisions.

9. Join products to plug-in busway: Move an existing productbeneath and in contact with plug-in busway. (You can also connectbusway to products with cable.) Move the product by clicking on anddragging it. (Feeder busway is drawn like cable; see step 6.) 10. Move, cut, copy, paste, or delete products: Several editingfunctions are available in Pow-R-Designer. You must first select theproduct (see step 8 above). Then perform the desired edit using menubar commands or toolbar buttons. See the Edit section in Chapter 2.,and Cut, Copy, and Paste sections in Chapter 3. Edit commands are available:• On the toolbar• By right-clicking in the drawing space, or• By clicking on Edit on the menu bar (see Chapter 2, Menu Bar

Commands).

11. Find (search for) a product: As a drawing job becomes largerand more complex, finding a given product in your drawing may takelonger by eye. Click on the Find button to display the Object Name list.Click on the designation for the object you want to find, then click onOK. The sought product becomes outlined. See Find sections inChapter 2 and Chapter 3.

12. Change product-label fonts: Drawing jobs may become complexto the point where labels overlap with products and each other. Or youmay prefer to enlarge them for visibility. To change a font, click onEdit, then on Font. Select the size and/or style you want, then click onOK. Click on a product to effect the change. All labels display therevision. Hot key = Alt E, F.

button on the toolbar), then on Prepare Schedule. Click on the fields ofthe products you want to appear in the schedule. Click on OK todisplay the schedule. To exit schedules, click on the close button on themenu bar. Hot key = Alt D, S. +While the schedule is displayed, clickon Schedules on the menu bar, then on Set Schedule Title to provide aname for the current schedule. This name appears on the printout only.Hot key = Alt D, T. See section on Schedules in Chapter 2. Note:You can save a Pow-R-Designer schedule as a .txt file in Notepad forediting purposes. However, a spreadsheet program manages yourinformation much more conveniently for performing those edits.

15. Create spec guide for drawing: In the process of placing aproduct, you work in a dialog box for that product. At this dialog box,click on the button Spec Data, then complete the information in thecolumn Value. This prepares Pow-R-Designer to create a specificationguide for the current drawing. When you have completed this processfor all desired products, click on File on the menu bar, on Export, thenon Spec Guide. Click on the folder where you want the specificationguide to reside, then type a name for it. Click on OK. Hot key = Alt F,E, S. See Export section in Chapter 2. Note: Specifications can begenerated for each individual piece of equipment in the one-line bycompleting spec data accordingly, or a single specification section canbe generated by completing one spec guide for each category ofequipment. 16. Export drawing to a CAD application: Click on File on the menubar, then on Export. Provide a name and a path for the current drawingin the displayed dialog box. Access this .dxf file later from your CADprogram. Hot key = Alt F, E, A. See Export section in Chapter 2.

General drawing strategyTesting and actual field use of Pow-R-Designer have shown that a “fan-out” product-placement processworks best: Attach larger products to the outside of their parent components, and group smaller productsnear the middle of those parent components. This makes products seem to fan out as you view the drawingoverall. This strategy is suggested to mitigate the grouping of bigger products. If larger products grouptogether, such groupings tend to choke pathways for smaller products and their associated cable which canresult in awkward placements and overlaps.Note: The larger the drawing, the more significance this strategy acquires.

To view and print yourspecification guide .rtf file,access it from a wordprocessing program,where you can also edit it.

Summary: Pow-R-Designer creates a .dxfextension for exporting toan editing program, a .txtextension for schedules,and an .rtf extension forspec guides.

Short Circuit Program Click on this command to calculateavailable short circuit fault current (red numbers in drawing). Bydefault, this value appears in red next to each product’s node.

Quick breaker substitution: Pow-R-Designer displays, ifneeded, a Change Itemsdialog box used forproviding alternativevalid breakers during theshort circuit analysis. Ifyou change specificationsat certain products(enclosed breaker, MCC,distribution panel, switchboard, and panelboard), breakersexisting elsewhere in the drawing may no longer be appropriate.The Change Items dialog box is designed to offer the leastexpensive (and safe) available breaker. This dialog box displays• where the existing breakers reside (“Designation”)• the name of the existing breakers (“Current”)• the available alternative breakers (“Change To”). Under Change To, each drop-down menu lists substitutebreakers according to cost, the top breaker being the cheapest.Note: To turn off the Change Items feature, click on Options onthe menu bar, then on Calculations. Click on the Breaker tab,then on the “Warn before changing breakers” field, removing thecheck from the box. When this feature is turned off, the ChangeItems dialog box does not appear when you perform a shortcircuit evaluation. Read the section on Calculations underOptions below.

A short circuit calcula-tion can only be per-formed if a utility en-trance is present in yourdrawing.

A short circuit analysisis necessary if youwant Pow-R-Designerto substitute the newbreaker.


23

Consistency Check† Click on this command to check that devicesupstream and downstream from transformers are the correct sizes.

Options Click on Options to display the commands Calculations,Display, Manufacturer, Schedules, and Snap to Grid.

Calculations‡ When you click on this option, a CalculationsOptions dialog box displays• a tab for the default system power factor that is used in voltage

drop calculations, and• a tab for automatic breaker substitution options Here’s how to use these tabs:

Voltage Drop: You can change this power factor by typing thevalue you want in the field System Power Factor (0.8 is thedefault). The voltage drop adjusts accordingly. Note: Be sureto run new calculations (voltage update, short circuit program,and consistency check) if you change this default value.

† In low voltage systems, you receive an error message if the motor voltage drop is >8.33% (>5% forall other devices). In medium voltage systems, you receive an error message if the motor voltage dropis >10% and >2.5% for all other devices. This calculation also checks whether each individual cablehas <3% voltage drop. ‡ Do not confuse this option with the menu item Calculations which contains Voltage Update, ShortCircuit Program, and Consistency Check.

Changing the systempower factor affects thedisplayed voltage dropcalculations and imped-ances.

Motor Load Contribution of Transformers in Short Circuit Calculations Service Transformer: The service transformer is the transformer occurring before the first switchboard, dis-tribution panel, or bus. If the motor load percent at this transformer is 100 or above, all other downstream motorloads in the system are not considered by the short circuit calculation. The only motor load taken into considerationis the assumed motor load of the service transformer. If the motor load percent of the service transformer is below100

*, all motor loads and motor contributions of transformers in the entire system are considered in the short circuit

calculation. Any other transformer: Motor contributions from this point downstream, in addition to the motor load percent atthis transformer, are all taken into consideration by the short circuit calculation. * The default motor load percent for the service transformer is 100. However, you may type a lower percent in this field. If you do, thenthe short circuit calculation for the service transformer takes into account the motor load contributions of all the other motors and trans-formers in the system. Otherwise it does not.


24

Auto-Change: At this tab, you control whether Pow-R-Designer updates yourbreakers due to a changein short circuit rating. Italso provides a way to seeyour intended selectionsbefore they actuallychange (a Change Itemsdialog box appears withall of your old and newbreaker selections. If the new breaker is blank, yourconfiguration is probably out of date. Edit the device manuallyto update your selections.). By default (see settings in dialog box here), your short circuitprogram automatically substitutes safer or less expensivebreakers in components if warranted by changes you made toyour drawing. If you want to see the Change Items dialog boxwhen you perform a short circuit calculation, make sure “Warnbefore auto-changing” is checked. Under Breaker Auto-change, the “Select the most cost effectivebreaker” option causes the Change Breakers dialog box toindicate a preference for a cost effective alternative breaker ifavailable (or no breakers if not available). If you choose “Keepassigned breaker if sized correctly,” the preferred breakerindicated is the one you chose previously for the component.

Chapter 5: Creating a One-LineDrawing—A Tutorial

Chapter 5 steps you through theconfiguration of a sample Pow-R-Designer one-line diagram (shown here). In this chapter you learn about:• Getting started• Parts-bin product placing• Editing• Calculations• Product schedules• Specification guide• Modifying text blocks• Adding Bitmap Images• Printing a drawing

Getting Started

If you have installed Pow-R-Designer, your Windows 95 Desktop orStart menu displays the icon or command you use to begin runningPow-R-Designer. (If you have not installed Pow-R-Designer, seeChapter 1: Pow-R-Designer Basics, page 1.) Double-click on theDesktop Pow-R-Designer icon or click on this command on the Startmenu. The default window appears.

To change the size of the drawing space, click on the drawing-size-control down arrow to select B, C, D, or E. The default size is A. Youcan change the drawing-space size at any time during the drawing

Figure 1: Refer to this drawing as you read theinstructions in this chapter.


58

process. The apparent size of your one-line does not change, but noticethat the scroll bars change size to indicate the difference.

The toolbar and parts bin buttons are arranged across the top of thePow-R-Designer window. Click on parts bin buttons to place productsin your drawing, and click on toolbar buttons to manage the drawing.These button groups are dockable; you can move them and reshapethem to station them where and how you want them. Click on the sideof one of these groups to relocate it; drag on a side to put it into adifferent form.

Save Your Work

Save frequently to protect your drawing and mitigate any problems youmay potentially encounter with computer malfunctions, softwareconflicts, or electrical outages. One of the more logical times to saveyour file is immediately after placing or reconfiguring a product.FBefore saving your drawing, run a short circuit program.

Save by clicking on the Save button on the toolbar, or by clicking onFile on the menu bar, then on Save. The first time you save a file, yousee the Save As dialog box. Use this box to name and assign your fileto the drive and folder you want.

Note: You should perform a short circuit program before saving orclosing a Pow-R-Designer one-line drawing. This practice ensures thatthe values displayed in the drawing are not obsolete, which would havethe potential for building an incorrect electrical system.

Qualification to This Tutorial

The core work of creating a one-line drawing—product placement—characterizes this section. Note, however, that technical aspects of thisprocess, such as determining which NEMA value to select or which kAto type in a field are not covered here. Your own determinations areconsidered the prime source for this kind of information. Provided hereinstead are ways to place products and navigate in Pow-R-Designer.

General Drawing Strategy

Testing and actual field use of Pow-R-Designer have shown that a "fan-out" product-placement process works best in a drawing. In otherwords, attach larger products to the outside of their parent components,and group smaller products near the middle of those parent components.As a result of this strategy, products look like they fan out as you viewthe drawing overall. This strategy is suggested to mitigate the groupingof bigger products. If larger products group together, such groupingstend to choke pathways for smaller products and their associated cablewhich can result in awkward placements and overlaps.

Creating the Drawing

A. Place the utility entrance The drawing at the beginning of thischapter shows a tap into the utility which provides power to thiselectrical scheme, so place this product in your own drawing.Unlike other products, the utility entrance product naturally has noprovision for a designation or specification data since it is acommodity a contractor does not supply, but instead taps into. (Theutility entrance product does however have the designation“Service” assigned to it by default.)

1. Click on the Utility Entrance button in the parts bin.2. Click on the location in your drawing space where you want to place

the utility entrance. A dialog box appears.3. Using the down arrow, click on the voltage class and voltage you

need. A default value appears in the field X/R Source Ratio. Typea value in the field Source.

4. Click on OK to place the symbol for the utility entrance in yourdrawing, or click on Cancel to nullify your selections and return tothe drawing space.

The larger the drawing,the more significance thisstrategy acquires.

Performing Calculations


73

The calculations you use with Pow-R-Designer drawings are UpdateVoltages, Short Circuit Program, and Consistency Check. Thesecommands appear under Calculations on the menu bar. (See side noteon nominal voltage, typical load current, and voltage drop in theSchedules section of Chapter 2.)

Update Voltages Click on Calculations on the menu bar, then onUpdate Voltages. Your drawing reassesses existing voltages at eachproduct after you make any additions or revisions. A voltage dropcalculation is also performed in this step.

Short Circuit Program Click on the Short Circuit button (or onCalculations on the menu bar, then on Short Circuit Program) tocalculate available short circuit fault current. By default, this value isdisplayed in red kA values next to each product’s node.

Consistency Check Click on Calculations on the menu bar, then onthe command Consistency Check. This function determines whetherdevices upstream and downstream from transformers are the correctsizes. You receive an on-screen report on the status of your system.Make adjustments in the indicated areas if necessary.
