Thank you for reading introduction.   Full Excel Spreadsheet Description: This Excel spreadsheet is in use by a professional electrical engineer for the design and construction of hundreds of millions of dollars' worth of projects including high-rise offices, hospitals, university campuses, suspension bridges, railroads and many other types of electrical projects. The design criteria are based on NFPA-70. Originally developed in 1998 it is revised several times into this current 168-pole version developed in Windows XP using Microsoft Excel macro enabled software. It is a rather large and complex but reliable spreadsheet and will take from 25 to 30 seconds to open depending on your computer speed. This spreadsheet is remarkably intuitive to the professional user in that it is based on the concept that many electrical distribution systems are three-phase AC power from the generation station to small branches. Substation, switchgear, distribution panels and panelboards usually use three-phase bus and wire systems. This spreadsheet takes full advantage of many of the programming features of Microsoft Excel® to make it a practicable valuable tool. The spreadsheet is fully annotated with comments that appear with a hovering cursor that give a detailed description of how each feature operates. By having this spreadsheet available for use by the electrical team thousands of hours of design and CAD time has been saved especially in the design and construction administration phases of a project. It is also an excellent stand­alone tool for making small individual designs and calculations quickly, completely and accurately. There are many electrical professionals who have used this spreadsheet for their work including designers, engineers, electricians and CAD operators who are delighted it is available and have become reliant on it. The name of the original Excel file is panelboard.xlsx. Save the file with a different name as many times as necessary. Repeat the process for each MDP, distribution panel, panelboard and switchgear on the project. The sheet where all data is entered is called the form and is appears similar to an actual panel with updating calculations as each load design parameter is added. Enter into the panel form the design criteria and the spreadsheet fills in all of the values for each circuit. A well-organized and detailed Panel Schedule automatically creates on the schedule sheet. Print the schedule or copy and paste the schedule directly into an AutoCAD drawing. Paste the schedule “with or without” updateable links. If the links are updatable any changes made on the opened excel file will automatically update the pasted schedule on the AutoCAD drawing the next time it is opened saving many hours of CAD inputting. The schedules will print on the AutoCad drawing as if they were drawn manually. The worksheets and workbook are protected and the formulas and tables hidden and not editable to prevent accidently changing vital information. Only cells on the spreadsheet form that have a white background are available for data entry. This includes the dropdown boxes. 1. Directly enter user data into the white cells on the spreadsheet form or select data from a drop-down menu. Enter first values for all criteria in the white cells then the results will populate blue cells. Incorrect values or too many numbers will cause the cell with calculations to show ###### instead of the correct data. If this happens simply enter the correct value. 2. The Blue cells display vales calculated by the program. Blue cells do not accept user input. 3. Inactive Yellow Cells fill in the form and display messages. Yellow cells do not accept user values. Message examples that can appear in yellow cells are: Panel connection has no neutral such as a 208-Volt 3?/3-Wire and a 120-Volt load exists. “NO NEUTRAL” Nonstandard motor specified such as a 100-HP single-phase 120-Volt motor. “Unavailable motor horsepower” User determined data to select or enter onto the spreadsheet Form Panel Details Enter Accessories such as: TVSS, Isolated Ground, etc Enter percent to Oversize or Undersize the panel main circuit breaker 100% = as designed) Standard ampere ratings.

Normally all panel schedules are saved on one or more drawings in the Electrical Set of drawings. It is convenient to save a blank original panelboard.xlsx file as the name of each panel you want to create. Enter values for the panel, feeder, each branch and loads connected to the panel. The Panel Schedule will populate and updated instantly with changes made on the Panel form. This schedule can be selected, copied, pasted and printed. Paste panel schedules into an AUTOCAD drawing with updateable links for future changes to the excel spreadsheet to carry over into the AutoCAD drawing. Copy and paste a Panelboard that is less than 168 Poles to the last poles used. AutoCad drawing will plot the properly pasted panel schedules to look like a Cad operator drew them in. Sometimes without elaborate paths specified each panel’s excel file must be domicile in the directory it is copied from and pasted into the drawings for the links in the drawing to find and update the AutoCAD drawing. This name and location must not change after pasting into the drawing in order for the updateable links to find it upon opening the next time. If the panel files location changes after pasting into an AutoCAD drawing you can update the path for the links to the new location of the panel schedule file from within AutoCAD. Save each Excel file with an intuitive name to recognize which panel and job it goes with. Thereafter as loads are added to or subtracted from a project and the changes are made in the appropriate Excel file form the AUTOCAD drawing will automatically be updated with the new information the next time the drawing is opened and can be plotted with all of the updates saving hours of CAD inputting and possible transfer errors.
