- We have used EPS on multimillions dollar projects that have been built and trusted
- Projects can be set up with two primary voltages such as 277-480V and/or 120-208V that may hundreds of branch circuit panels and thousands of loads. Other world voltages may be used based on user input
- We use .NET Framework 4.5 or greater and object-oriented code-compliant compilers so users get the latest Windows software. We couldn’t build such a complex program without it
- Project logs that keep track of time spent in each panelboard and time if users edited or viewed
- Users can choose to use multiple sources of power input such as existing panelboards or utility transformers
- Manual minimum AIC input for existing panelboard or calculated AIC for utility transformers
- Built-in calculator for solving voltage drop, conduit fill, solving for HP, KW, KVA, and amps
- Full-time event log viewer with date/time and event, per session and file backup
- Users are asked if a backup is required each time a project is opened, in case of a user input error or riser calamity
- All windows are dual monitor, 4K resolution, and size/location memory compliant
- Change print/export options
- Users can adjust many startup factors on new panelboards such as:
Minimum/maximum wire size
Default conduit, wire insulation, wire type for feeders
Default conduit, wire insulation, wire type for circuits
Template panelboard (most commonly used)
Default KVA or KW input load switch
Default connected or demand load switch
Feeder volt drop in percent variable (3%)
Voltage drop percent power factor variable
Run wizard be default or manual on the load input switch - Input project due date
- Point to point Fault protection calculations
- Ability to adjust the brightness of the panelboard editing window
- Calculator for solving X/R of utility or service transformers for available short circuit current with impedance/reactance and Bussman charts that also calculate secondary amps with breaker requirements
- Branch circuit transformer entry form windows show all connections to it, available short circuit current, primary and secondary OCP size
- All branch circuit transformers can be exported to a schedule with many printing options and notes
- Full-time voltage drop calculations for each circuit with 3% panelboard and 5% drops to utility warning that will allow users to clearly see when they occur
- Automatically calculated with manual size adjustment for breaker, feeder, neutral ground, and electrode sizing for feeder or branch circuits
- Users can size circuits based on a “circuiting wizard” or manually input KW, KVA, or Amps loads
- Constant project/panel summary loads shown in demand or connected and amps, visible from multiple locations
- Bill of materials for wire and conduit
- All exports can use PDF, Excel, or HTML and schedule can also export into AutoCAD
- Revit parameters import that will all circuits are shown in Revit or another tab-delimited file
- Drag and drop riser trees that will connect and size wire and breakers. Users only have to determine the breaker size (if greater or smaller than the assumed value) and a circuit number
- Riser tree editing:
- Double click to edit or view panel or transformer (there are two distinct dialogs for their respective entry)
- Color-coded and icon-based so user exactly what is being selected
- Refresh riser button so when there are many riser elements there would not be a slow down when not needed
- Select any element will instantly display properties in an info window
- Searchable riser list
- Collapsible riser tree
- Export to riser info and panelboards to excel in seconds
- Panel names are visible along with bus size (or transformer KVA) making it very easy to distinguish which element is being selected
- Export one or all panelboards to excel with one click (this process is so fast we had to put a user variable timer in the code that would slow down the export speed because the hard drive could not keep up with the process)
29. Electrical panelboard editing: - Double click to edit any circuit
- Select any circuit to display or change its properties like wire size, conduit, wire type, wire insulation, breaker tag, type breaker, neutral rating, breaker rating, and many other aspects
- Panel properties are broken into a tabbed window making it easy to separate the properties they are meant to represent. These schedules are broken down to appear with odd on the left and even on the right making it easy to assign circuits and share conduits with its respective group
- Users can name any created panel as a new name and use them on other projects if that is a commonality between one and another
- Users can name groups of the circuit (sharing a common conduit) to a 3P, 2P, SN and define these groups with 5 different colors that are easy to delineate when viewing the schedule
- There is a switch that will allow users to change how loads for 2 or 3 pole circuit are displayed in the schedule (as well as exporting) that combine its load based on balanced, load per phase, or combined
- Drag and drop copy, edit or move within the panelboard edit window
- Export any panel to AutoCAD, Excel PDF, or HTML
- Easily change all aspect of panelboard properties
- Easily change to one or two section panel that will split the panelboard when exported
- Easily switch between KW or KVA loads summery for panel or loads
- Warning messages that warn on unbalanced loading between phases, bus amps warning, if load amps fall below bus amps, feeder wire size below voltage drop requirements, breakers that adjacent to each other are not allowed on its bus section (framing), and many other common requirements based on a panelboard use
- Schedule notes text entry
- Detailed materials list
- A detailed report that shows an overall data view similar to schedule output
- Methods for marking breakers that will be visible in the schedule when it is exported, such as GFCI, shunt trip, or anything a user can think of
- Each circuit has a visible wire length
- Easily see panel length to utility and AiC ratings if it is connected to utility
- Easily see a panelboard power source
- Copy circuits from exiting panel data files from any project, provided they are the same voltage
- Populate any number of circuits with one similar circuit to a range of spare or space poles, so long as they as sequentially adjacent
- Populate any number of circuits with a spare and if any vary with default minimum breaker size, can easily be changed.
- Constant visibility to wire size, load, voltage drop warning, and many other circuit characteristics
- Ability to easily change the calculated wire, breaker, conduit neutral, and ground
- Colored backgrounds groups of shared poles that share a conduit, so it makes it very easy to distinguish between these groups
- Free space notice in spaces and percentage
- View loads for each phase, total and combined with connected/demand and amps for each
- Users can view loads for each side of the panelboard as an indication of the load balancing per side
- Users can input size dimensions, cost, room number, and manufacturer information
- Right-click on any circuit to increase/decrease wire size, to allow change from voltage drop
- Right-click on any circuit to increase/decrease conduit size when a wire has been changed
- Right-click to change the background color of any circuit shown in the schedule
- Right on any circuit to duplicate it to any number of spaces or spares (must be lower sequential order but will not over-right valid breaker slots)
- Users may change names of the circuit in the scheduler one after another (helps to mass edit circuit names without opening each circuit edit window)
- AutoCAD exports are marked two and three pole breakers and easily recognizable group
- AutoCAD exports are marked shared neutral as an easily recognizable group
- Users can select between Amps, KW, or KVA when entering loads in panelboard circuits as well as power factors
- When sizing any wire in EPS there is are constant calculations showing the amps the selected wire is rated in 310.16, the voltage drop across the wire, and voltage drop percent.
- When sizing a ground the chart in NEC 250-122 is visible.
- When sizing conduit in EPS there is a calculation showing conduit fill factor and filled square inches
- Voltage drops for each circuit can be exported to Excel along with conduit fill factor calculations when exporting (switch in printing options)
- When sizing a breaker in EPS there is a calculation that shows the percentage above rated amps
- Easy access to cheat sheets inside EPS
- Ability to lock circuits from any changes to breaker or wire increases when an edit is made
