Option Description

Design Library Sheet

Select the design template you want to use. The design templates are stored as design sheets in the standard library (Stdlib.mdb). The library has a default design sheet named “Generic.” You can create your own design templates in the library. For details on creating or editing design sheets, see Design Library.

Generate Report Only Without Changing Data

This enables you to view comments regarding existing design (size/ratings) of equipment, without changing design (data). When this is not selected, the equipment sizes/ratings can be changed upon running Auto Design.

Create Bill of Materials Report

Creates a Bill of Materials report for the items that are auto-designed.

Downstream load based on

Select the type of load current calculation to use to size equipment. The following choices are available:

  • Connected Amps: Amp value for the total kVA of all downstream loads.
  • Demand Amps: Amp value for the total (kVA * Demand Factor) of all downstream loads.
  • Code Factor Amps: Amp value calculated using appropriate code factors and demand factors, following a Code (such as NEC).
  • Design Amps: Amp value calculated using appropriate code factors and diversity factor and Design multiplier.
  • User-Specified Amps: You can specify the amp value for designing selected equipment while you perform Auto Design. The figure below is an example of the dialog you will get to enter the amp value when sizing a cable “C-2.”

Sizing MCCs/Panels on One-line

MCC and Panel schedules include different components such as main (breaker/fuse), bus, feeder breakers/fuses, feeder cables, etc. You can select what items to size by selecting the appropriate choice:

  • Size Everything
  • Size Bus, Main and Feeders
  • Size Bus and Main Only
  • Size Bus Only
  • Size Main Only

Default Motor Starter

Selects which type of starter to use in the MCC feeder description when sizing MCC.

SC Threshold (%)

When the estimated short circuit current through an equipment is greater than the specified threshold value of the equipment short circuit rating, a warning is provided in the report. A threshold of 20% corresponds to 0.8 * Equipment Rating.

Show extended comments for series coordination

This option provides more detailed comments when performing series coordination between protective devices.
