Built-In Time Saving Tools

 

AIC Ratings are calculated and applied automatically based on the available fault current found from the short circuit calculations and the voltage rating of the bus.

 

Load calculations at the local bus run automatically as new load information is entered.

  • The load calculation tables provide code references for each load type (where applicable) for the user to review the code requirements associated with applying that load type and for understanding the load calculation for that load type.

  • Residential and Hotel Room calculations are based on the area of the space served. The input screen provides a cell to define these area sizes in square feet that can be used to calculate the loads per the NEC. The areas for the local, sub-feed, and totals are shown to facilitate manual verification of the calculations.

  • The diversity allowed for several load types is based on the quantity of devices fed. Each input screen for each bus includes tables that show the quantity of circuits assigned for that load type so the load calculations can be manually verified. These quantities are listed for the local bus, all sub-feed buses, and the total count from all buses.

  • The diversification for several other load types is based on the largest load, 2nd largest load, etc. The load calculations keep track of the largest loads from the current active bus and all sub-feed buses and displays this information for the user to view. The diversities are calculated based on each of the largest loads tracked.

  • When a user exits a bus, all loads back to the source Utility (and Generator(s) if present) are calculated automatically.

​

A Built-In pop-up Voltage Drop Calculator solves for:

  • Voltage Drop

  • Maximum feeder length

  • Minimum conductor size

  • When this VD calculator is opened from within a bus, the VD calculator auto-populates the voltage, load, and feeder data as the starting point for reviewing the VD calculations.

 

A Built-In pop-up SCCR Calculator

  • Calculates the Short Circuit Current at equipment with SCCR Ratings.

  • When this SCCR calculator is opened from within a bus, the SCCR calculator auto-populates with the voltage and available fault current to facilitate calculating the available fault current at equipment fed from that panel.

​

A "Feeder Summary" worksheet is included that lists every feeder in the electrical distribution system. This worksheet displays the available fault current and the VD at each bus. The user can change the feeder size, Cu/Al, magnetic/non-magnetic, and feeder length values and see the updated calculated values in real time.

​

Insert Text into a selected range of cells

  • Adds text at the beginning or end of each selected cell.

  • Examples

    • Adding “(E) ” at the beginning of the Load Description

    • Adding “ *” at the end of a Load Description

 

Repair Sheet Tool

  • Dragging and Dropping cells in a spreadsheet can corrupt formulas within a worksheet. The Repair Sheet Tool restores all formulas on a worksheet to their default condition.

 

Clone Panel

  • Creates a user-specified number of clones using a selected bus as the template.

  • This is particularly useful in projects with multiple panels of one configuration.

 

Copy Panel Input

  • Copies the loads from one panel into another panel.

  • This is particularly useful for apartment buildings.

​

Import from previous NEC Code Cycles

  • Can import a Panel Schedule file from a previous Code Cycle into a newer Code Cycle Panel Schedule. This will support importing from the previous two Cycles. 2017 to 2023 and 2020 to 2023 .

    • This is particularly useful if the AHJ adopts a new Code Cycle during the design process.​

  • If a Panel Schedule file gets corrupted, the import will allow importing from the same Code Cycle, 2023 to 2023.

 

Error Report

  • Produces a report of potential errors or warnings which include:

    • Input Errors (text when an integer was expected).​

    • The OCPD Pole count does not match the Load Requirements (for example, a household electric dryer is required to use a 2-pole OCPD).

    • A Bus is Overloaded.

    • A Branch Circuit is Overloaded.

    • A Bus that cannot exceed 42 poles (Some panel configurations limit the panel to 42 poles. When a panel is limited to 42 poles and loads are connected to poles 43-84, then this error is flagged).

    • The Source OCPD : Branch OCPD ratio is less than 3:1 (This is a warning to facilitate systems that require Selective Coordination).

    • A Branch circuit breaker exceeds 100 Amps on a Branch Panelboard (the largest branch circuit breaker allowed on a Branch Panelboard is a 100 Amp Frame Breaker).

 

Global Settings

  • Voltage Drop calculations can use either 80% of the Bus Rating or the Design Load in calculating the voltage drop at each bus.

  • AIC Ratings can be calculated at either 100% or 120% of the calculated SCA value.

  • Lighting Load Calculations can use either the values from NEC 220.12 or NEC 220.12 Ex. 1.

  • Feeders can be limited to all Copper Feeders or they can be configured to allow Aluminum Feeders.

    • Toggling this parameter will automatically change all feeders from Aluminum to Copper and back again.​

  • Transformers can be limited to all Copper Windings or they can be configured to allow Aluminum Windings.

    • Toggling this parameter will automatically change all Transformer Windings from Aluminum to Copper and back again.​

  • Buses can be specified as all Copper Buses or they can be configured to allow Aluminum Buses.

    • Toggling this parameter will automatically change all Buses from Aluminum to Copper and back again.​
