II Introduction: ------------- ELECTRC8 is designed to perform most common electrical contracting and engineering calculations : * Device, junction and pull box calcs. * Conduit size selection for many combinations of different wire sizes & types. * Determine the cost to operate various loads at different kwh charges. * Lighting calculations based on zonal cavity method. * Motor conductor, overcurrent and overload calculations. * Calculate required wire and conduit size based on allowable voltage drop. * Quick reference tables for: Grounding electrode conductor size Equipment grounding conductor size Underground cover requirements KW to ampere tables Transformer Kva to ampere tables Metal device box size and capacity Standard fuse & breaker ratings Standard pull & junction box table * Calculate voltage drop for various loads, voltages, wire size and run lengths. * All functions operate with 'what-if' capability. You can quickly and easily change only the data you wish to, without having to start a new calculation and re-enter all the required data. Results are calculated and displayed as you make each change. ** All functions conform to the 1990 National Electrical Code. The National Electrical Code is a copyrighted document of the National Fire Protection Association, Batterymarch Park, Quincy, MA. 02269. Page 1 MAIN MENU: --------- To run ELECTRC8, insert the program disk into the disk drive and type ELECTRC8 then press ENTER or RETURN. The program starts up with an opening screen with a prompt for you to input a random number as displayed. Enter the number exactly as it is displayed. The main menu will follow. The main menu is a pull down type, structured as a horizontal bar at the top of the screen with main titles displayed. Each of these main titles represents a sub menu with one or more related program functions. To select specific program functions : 1. Press the hilighted letter of the menu item (main or sub). OR, 2. Press the DOWN ARROW key to open the first sub menu, then use LEFT or RIGHT ARROW keys to move between sub menus. OR, 3. Position the hilighted block over a menu selection (main or sub), then press ENTER. DATA INPUT: ---------- All functions now have 'What-If' data entry routines. This method of data input and calculation allows you to instantly see the results of changing one data item at a time. You will not need to restart the function from the beginning and re-enter all data just to see the effect of changing one parameter. The data input routines are similar in all functions. Use the UP and DOWN ARROW keys, or ENTER, to move between input fields, entering data as you go. Some fields limit your input to certain values, and if you input data that is unacceptable, you will hear a beep and will not be able to move from that field until the correct data has been entered (or you leave the field empty). Some functions require that you select one data item from a list. This is done by pressing a function key which pops up a menu where you will select one item from a list of choices. Use the UP or DOWN ARROW keys to position the hilighted bar over your choice and press ENTER. After you have entered all required data, the calculation will be performed and displayed. You can then change individual data items and instantly see the results. CAUTION: When entering the last data item, or changing one data item which was previously entered: Be sure to record that change by moving from that field to another field, or by pressing ENTER while still on that field. Page 2 DEVICE BOX FILL CALCULATIONS: ---------------------------- Determines cubic inch volume required for boxes, as per NEC section 370-6. Conductor size range is from #18 thru #6. Free space (cubic in.) required for each conductor is as follows: ---------------------------------------- # 18 .. 1.5 # 10 .. 2.5 # 16 .. 1.75 # 8 .. 3 # 14 .. 2 # 6 .. 5 # 12 .. 2.25 Deductions are as follows: ------------------------- 1 or more Fixture studs, cable clamps, hickeys 1 deduction Each Strap containing 1 or more devices ....... 2 deductions 1 or more grounding conductors entering box ... 1 deduction 1 or more Isolated Ground conductors .......... 1 deduction Enter the quantity of each size conductor within the box: --------------------------------------------------------- A conductor running thru the box with no splices or connections within the box should be counted as 1 conductor. A conductor originating outside the box and terminating within the box should be counted as 1 conductor. Conductors, no part of which leaves the box (example ... a jumper or pigtail from a splice within the box to a switch, outlet or fixture mounted on the box), should not be counted. ** One or more grounding conductors, or, a second set of grounding conductors (isolated ground ), should not be included in this conductor count. They will be asked for later. Answer the prompts for devices, clamps, fittings, ground conductors, add'l ground conductors: --------------------------------------------------------- Count each mounting yoke or strap containing one or more devices as 1. Example... one duplex outlet - count as 1. two duplex outlets - count as 2. The remaining prompts are self explanatory. Answer Y for yes. There is no need to answer N for any prompts which would be answered as 'no'. A blank field is interpreted as 'no'. A quick reference table of standard metal boxes and their cubic inch capacity is available for viewing at any time, by pressing F2. The current screen will be saved, and the table will be shown. When you wish to return to the previous screen, press any key. Page 3 JUNCTION, PULL BOX CALCULATIONS: Straight Pull: ------------- Calculates the minimum length, in inches, of pull and junction boxes where raceways enter and leave the box at opposite ends. If the wiring method is cable assemblies instead of raceways, first determine the trade size conduit which would be appropriate for the size and quantity of conductors in the cable assembly, then use that conduit size. If more than one raceway or cable enters and/or leaves either end of the box, always use the largest size. The method used to determine minimum box length for straight pull: Eight times the trade diameter of the largest raceway. The operation of this function is straightforward. Position the hilighted bar over the largest raceway size for this calculation, then press ENTER. The results will be displayed. Angle or U Pull: --------------- Calculates the minimum distance, in inches, between each raceway entry inside a junction or pull box and the opposite wall of the box, where raceways enter and leave the box at angles. If the wiring method is cable assemblies, see the explanation above, under 'Straight Pull'. The method used to determine minimum distance for angle or U Pull: Six times the trade diameter of the largest raceway, PLUS, the sum of the diameters of all other raceway entries in any one row on the same wall of the box. Use the row with the largest total diameter of raceways. A quick reference table of standard boxes and their cubic inch capacity is available for viewing at any time, by pressing F2. The current screen will be saved, and the table will be shown. When you wish to return to the previous screen, press any key. Page 4 CONDUIT SELECTOR: ----------------- The Conduit Selector allows you to quickly and accurately determine the conduit size required for 1 or more conductors. Calculations are based on the Dimensions and Percent Area of Conduit and Tubing from table 4, and from Conductor Dimensions as per Table 5 of the NEC. Maximum allowable percent conduit fill is 53% for 1 conductor, 31% for 2 conductors and 40% for more than 2 conductors, as per table 4. Use the UP, DOWN, TAB or SHIFT+TAB keys to move the cursor to the desired wire size/type position, then enter the quantity of that size/type conductor to include in the conduit. If you want to include other size/types of conductors into the same conduit, then repeat the above procedure. You can enter any combination of conductors in the same conduit. NOTE: Several fields will show an asterisk ( * ). This represents the unavailability of those sizes/types of conductors. Do not alter those fields. Pressing F2 at any time will show the results of the calculation. The program will list all the sizes and types of conductors you chose for the calculation, their individual areas, the total area extensions, the grand total area for all conductors, the minimum trade size conduit required, the total area for the calculated conduit, and the percent conduit fill for the calculation. If more data is available than will fit on the screen, you will be able to use the UP and DOWN ARROW keys to scroll through the data. Pressing any key will return you to the conduit selector input screen with all previous data intact. GENERAL CALCULATIONS Cost to Operate: --------------- Calculates the cost to operate a certain load a number of hours daily for some number of days at a certain KWH utility charge. POWER OF LOAD is the number of WATTS the load draws. DAILY USE is the number of HOURS the load is operated per day. NUMBER OF DAYS is the number of days the load is operated. PRICE / KWH is the utility charge per killowatt hour. (Example.. 10 cents/kwh, enter .10) NOTE: A value of ten cents/Kwk initially appears in the 'Price/Kwh' field, as an example only. You should change this value to reflect your own price/Kwh charge. After entering the above information, the program calculates and displays the cost to operate the load for the number of hours daily for the number of days at the chosen utility charge. Page 5 LIGHTING CALCULATION ( Zonal Cavity Method ): -------------------------------------------- Calculates the quantity of lighting fixtures required to light any room or area to any desired footcandle level. The Illuminating Engineering Society (IES) has devised a flexible and accurate method for calculating lighting requirements, called the ZONAL CAVITY METHOD. This method assumes that any room or area to be lighted is made up of three cavities, the CEILING CAVITY, the ROOM CAVITY, and the FLOOR CAVITY. The CEILING CAVITY extends from the ceiling surface down to the lighting fixture mounting level. If the lighting fixtures are recessed or surface mounted then the value of the Ceiling Cavity will be zero. If they are suspended some distance below the ceiling then the value of the Ceiling Cavity is the volume of space between the ceiling surface and the fixture mounting level. The ROOM CAVITY extends from the fixture mounting level down to the work height level. The work height level is the distance above the floor where the required quantity of footcandles is to be maintained (usually desktop or work bench level). The FLOOR CAVITY extends from the work height level down to the floor. If the required footcandles is to be maintained all the way to the floor, then the Floor Cavity value will be zero. Every surface exibits a certain ability to reflect light. Light colored surfaces reflect more light than dark surfaces, so more light will need to be provided in a dark environment. The degree of a surface's reflectivity is referred to as it's Percent Reflection value. Percent Reflection can be accurately measured with a reflectometer, or standard reflectance tables can be referred to, such as the following: TABLE FOR INTERIOR ILLUMINATION DESIGN ---------------------------------------- COLOR % REFLECTION ---------------------------------------- Flat white 75 - 85 Ivory 70 - 75 Buff 60 - 70 Yellow 55 - 65 Light tan 45 - 55 Light green 40 - 50 Gray 30 - 50 Blue 25 - 35 Red 15 - 20 Dark brown 10 - 15 ------------------------------------------ Page 6 The MAINTENANCE FACTOR is a value determined from the anticipated maintenance of the fixtures and reflective surfaces in the room or area. The intensity of illumination produced by a lighting installation will depreciate after some time due to lamp aging, and dust and dirt buildup. The MAINTENANCE FACTOR is designed to adjust for this. Typical values are from .5 to .8. (.5 for a poorly maintained environment, .8 for well maintained). Each lighting equipment manufacturer publishes data for the COEFFICIENT OF UTILIZATION (CU) for each fixture type and size in it's line. The CU of a fixture is a measure of it's efficiency under specific conditions of room cavity values and effective reflectance values. The formulas used in the ZONAL CAVITY METHOD : CEILING CAVITY RATIO = (5 * Hc (L + W)) / (L * W) ROOM CAVITY RATIO = (5 * Hr (L + W)) / (L * W) FLOOR CAVITY RATIO = (5 * Hf (L + W) / (L * W) WHERE: Hc = distance from ceiling to fixture level (in feet). Hr = distance from fixture level to work height (in feet). Hf = distance from work height to floor (in feet). L = length of room in feet. W = width of room in feet. ROOM LENGTH and ROOM WIDTH values must be entered in FEET. Decimal points are accepted (Ex. 125, 50.5, etc...). CEILING HEIGHT and FIXTURE HEIGHT must also be entered in FEET. Decimal points are acceptable. WORK HEIGHT must also be entered in FEET. Decimal points are acceptable. If you want the WORK HEIGHT to be equal to the floor, simply enter zero. FOOTCANDLE LEVEL is a measure of the intensity of light falling upon a specific surface. Page 7 Values for Percent CEILING, WALL, and FLOOR Reflectances must be entered as whole numbers (50, 80, etc...) Exact values can be obtained by use of a reflectometer, or a standard table for interior illumination design can be referred to, such as the table for interior illumination design on the previous page. The value entered for MAINTENANCE FACTOR must be less than or equal to 1. The value of between .5 and .8 will be accurate for nearly all calculations. A value of 1 will exclude the MAINTENANCE FACTOR from the lighting calculation. NOTE: A value of .8 initially appears in the 'Maintenance Factor' field, as an example only. You can change this value to reflect your own conditions. To select fixture type, press F2. The menu will ask you to select either 'built-in fixture type' or 'specify fixture type'. Built-In: --------- Fixture types stored internally include Recessed Incandescent, Fluorescent, and High Intensity Discharge. COEFFICIENT of UTILIZATION (CU) values which have been compiled by IES are stored internally for these fixtures. The internally stored fixtures are representitive of their types, as are the internally stored lamp types. You will get accurate results using them, but if you wish to use a type of fixture not available internally, you can choose to specify your own type. Specify: -------- If you choose to specify your own fixture type, you will be prompted for the number of lamps per fixture, the quantity of lumens per lamp, and, the coefficient of utilization (CU) of the fixture. You will need to have the fixture manufacturer's CU specs. LUMEN specs are available from various sources. Lamp manufacturers will have lamp catalogs which will list LUMEN values for their line of lamps. After all data has been entered, the number of fixtures required will be calculated and displayed. Page 8 MOTOR CALCULATIONS: ------------------- Branch Conductor Sizing: ----------------------- Calculates motor branch circuit conductor size. NEC Article 430- Part B, and, 430-6. Conductor ampacity is based on 125 percent of motor full load amperage, as determined from table 430-148. Conductor types supported include THW, THWN, THHN, XHHW Copper, THHN, XHHW Aluminum. Fuse or Breaker Sizing: ---------------------- Calculates rating or setting of motor branch circuit overcurrent protective device (Nontime-delay fuse, Time delay fuse, Instantaneous trip circuit breaker & Inverse time circuit breaker). NEC Article 430-Part D, and, 430-52. Rating or setting is based on Full load amperage (from table 430- 148) of motor, multiplied by appropriate percentage factor from table 430-152 for the selected device type. Article 430-52(a). If this results in a value other than a standard size or rating of overcurrent protection device, the next higher standard rating is selected. Article 430-52(a), Exception 1. Overload Protection Sizing: -------------------------- Calculates motor overload protective device rating. Article 430, Part C. Rating is based on motor full load amperage (from motor nameplate) multiplied by: 125 % if nameplate marked service factor is not less than 1.15, or 125 % if nameplate marked temp. rise is not over 40 degrees C., or 115 % for all others. Access Keys Used To Select Motor, Wire & Overcurrent Parameters: ----------------------------------------------------------------- Press: To Select: Press: To Select: -------------------- -------------------- F4 Volts F6 Code Letter F5 Horsepower F7 Wire Type F8 Overcurrent Type At the 'Percent Motor Power Factor' field, entering 100 will assume 100% power factor and exclude the motor's Power Factor from the calculation. After all data has been entered, the calculation will be performed and the results will be displayed. Page 9 PIPE & WIRE SELECTOR: --------------------- Calculates the conductor size required to carry a certain load for some distance while not exceeding a specific voltage drop percentage, and the trade size conduit required to contain those conductors. Conductor types supported include THW, THWN, THHN, XHHW Copper, THHN, XHHW Aluminum. Conductor ambient temperature derating is supported, according to the ampacity correction factors at the bottom of NEC Table 310-16. Conductor ampacity derating due to the number of current carrying conductors in the raceway is supported as per NEC 310-Note 8(a). Six circuit types are supported: -------------------------------- 1 Phase 2 Wire(Phase & neutral, or 2 Phase conductors) 1 Phase 3 Wire(2 Phase conductors & neutral) 1 Phase 3 Wire(Above circuit from a 4 wire wye system) 3 Phase 3 Wire(3 phase conductors) 3 Phase 4 Wire Wye(3 phase conductors & neutral) 3 Phase 4 Wire Wye circuit with the majority of load consisting of electric discharge lighting, computers, or similar equipment. In the third circuit type above, the neutral will carry substantial current, and will be considered as a current carrying conductor in the pipe size selection. NEC 310-Note 10(b). In the last circuit type above, the neutral will carry harmonic currents, and will be considered as a current carrying conductor in the pipe size selection. NEC 310-Note 10(c). Data Input: ----------- The 'Maximum Percent Of Voltage Drop' field will only accept whole numbers in the range of 0 to 9. This will be the maximum percentage of the supply voltage which can be dropped by the circuit conductors. If you enter 0 in this field, voltage drop will not be considered in the selection of the wire size. The 'Full Load Amperage Of Load' is the rated or maximum amperage. The 'Source Voltage' is the supply voltage for the circuit. The 'Length of Run In Feet' is one way length from supply to load. Press F2 to select the circuit type. Press F3 to select the wire type. Press F4 to select ambient temperature of the circuit conductors. After you have entered the data, the program will calculate and display the required conductor and pipe size.
