New and Enhanced Feature Details

IEEE 1584-2018 Support

This release includes updates to the program calculations and options to support the new IEEE 1584-2018 standard.

New Standard Calculation Method

In the Short Circuit Options, references to the older IEEE 1584 standard have been renamed to IEEE 1584-2002 and older databases where that standard was selected are now set to use IEEE 1584-2002. When you create a new one-line, the default is now IEEE 1584-2018.

The new method applies the complex calculations described in the IEEE 1584-2018 standard to determine the arc flash incident energy and arc flash boundaries.

Figure 1: Arc Flash Standard Name Changes

When the IEEE 1584-2018 standard is selected, the options for user specified worst case arcing current are removed as this value is calculated based on system parameters with the new standard. The calculated arc flash method defaults to Integrated for new databases. In addition, there are now separate working distances for switchgear in the Enclosed table. This enables you to specify a working distance for switchgear that is different from the other equipment types.

Advanced Arc Flash Options

In the Advanced Arc Flash Options dialog box, there are a number of changes to address updates in the IEEE 1584-2018 standard. The dialog box has been reconfigured to better display the available options.

Arc Flash Hazard Tab Updates

The Arc Flash Hazard tab that appears in automatic transfer switches, buses, tool points of connection, MCCs, and panels have all been updated with new parameters to accommodate the IEEE 1584-2018 calculations. The new fields include Electrode GapElectrode Configuration, and Enclosure Size. You can use the defaults from the device library, or you can select to use your own user-specified values. You can customize the library defaults by voltage and equipment type.

Figure 4: Arc Flash Hazard Tab

The electrode configuration, enclosure sizes, and electrode gap can be included as variables on custom arc flash labels. 

Electrode Configurations

The new standard introduces new electrode configurations for arc flash hazard analysis. These include:

Electrodes in Enclosures:

Electrodes in Open Air:

You can specify the electrode configuration on the various equipment where arc flash hazard can be calculated. See the Help file Arc Flash Hazard Tab Updates.

For older EasyPower databases that are opened in the 10.2 version of the program, the electrode configurations are upgraded as shown in the table below.

Original Orientation New Electrode Configuration
Vertical Default from Library
Horizontal User Specified - HCB
Vertical Into Barrier User Specified - VCBB
Open Air Default from Library

See Electrode Configuration for more information.

Device Library Updates

The device library has been updated to represent the new IEEE 1584-2018 standard. There are now separate tables for NEMA/ANSI and IEC rather than separate columns in the same table. There are now separate tables for IEEE 1584-2018, IEEE 1584-2002, and V7.0 Enhanced.

The library now includes columns for electrode configuration and enclosure sizes, and the library data has been expanded to include standard gap and enclosure information. You can customize the library defaults by voltage and equipment type. The voltage range that was previously from 0.2 to 1.0 has been split into 0.201 - 0.600 and 0.601 - 0.999.

Figure 5: Arc Flash Hazard Defaults in the Device Library

You can specify more than one electrode configuration in the library, if needed. For the IEEE 1584-2018 standard the program determines the highest incident energy based on the existing electrode configurations when calculating the arc flash hazard.

Upgrading the Device Library

As of EasyPower 10.2, the Arc Flash Hazard Defaults tables in the device library now include a new table for IEEE 1584-2018. As a result of this change, EasyPower displays a warning if you open a one-line database that is connected to a device library for a version prior to EasyPower 10.2.

You can still open the database file using the older device library, but if there are default values that are not defined in the older library, EasyPower uses the program default values.

You can upgrade an older device library by opening it in EasyPower 10.2. The device library files for versions prior to 10.2 are upgraded as follows:

Arc Flash Hazard/Scenario Comparison Report Changes

The Arc Flash Hazard and Arc Flash Scenario Comparison Reports have new columns, including:

The following columns have been renamed:

Original Name New Name Notes
Arc Gap Electrode Gap The gap can come from the library or be specified on the item. The unit is always shown in millimeters.

Required Clothing Description


PPE / Comments

In prior releases, the column text changed depending on whether PPE level was selected to be shown in the Arc Flash Hazard Options. This column retains its dual nature as in earlier releases but now both names appear in the heading.

The column remains available for older databases but has been replaced with the new separate columns for PPE Level and Comments.

Label Comment Equipment Label Comment  
Labels to Print Equipment Label Quantity  
Device Comment Device Label Comment  
Device Comment Count Device Label Quantity  

For the new IEEE 1584-2018 calculations, the arc flash results in the Arc Flash Hazard report that are derived using the reduced arcing current are displayed in pink text, similar to how the worst-case arcing current has been displayed on the report in the past.

The pink text means the maximum incident energy was calculated using the reduced arc current. The black text means the maximum incident energy was calculated by using the average arc current in the IEEE 1584-2018 standard.

As with previous releases, blue text indicates the cell can be edited, and the calculations will be updated using the new values.

Figure 7: Colored Text in the Arc Flash Hazard Report

The default columns on the reports change based on the arc flash standard selected, so that columns that are not applicable to the selected standard do not appear.

Work Task Changes

The Work Task Dialog now has an option to select from one or multiple electrode configurations.

Database Browser and Database Report Changes

There are new columns in the Database Browser and Database Report for:

In addition, the following columns have been renamed:

Original Name New Name Notes
Forced WD Working Distance Setting Displays either "Default" or "Specified."
WD Value Working Distance

If the equipment's working distance is user-specified, the report displays the user-specified value. Otherwise it will show the value as retrieved from the first column of the table in Short Circuit Options > Arc Flash Hazard, based on the equipment voltage and equipment type. Note that there are two tables: one for open air and one for enclosed.

Units are based on the setting in Options > System.

Panel Row Behavior Changes

We have made changes to the way that panel rows work. The cells for the load values for the A, B and C phases are now arranged diagonally and we have modified what happens when you insert and delete rows.

Phases and Poles

The phases and number of poles for the circuit affect the panel row behavior. Below is an image of a three-phase panel with a mixture of poles. The phases appear diagonally for each row, with phase A in the first row in the first column, phase B in the second row in the second column, and phase C in the third row in the third column. This phase pattern repeats throughout the spreadsheet.

The number of poles indicates how the rows are grouped together to make up a circuit. For example, rows 13-17 are grouped because the number of poles is set to 3. Rows 19-21 are grouped together because the number of poles is set to 2. The remaining rows are all individual because the poles are set to 1.

Figure 9: Panel Rows in 3 Phase (Detailed View)

As a result of this change, the behavior when inserting, deleting, or moving rows has changed. You can also clear a panel row without removing it. See the Help file Panel Row Behaviors for details.

We have also changed the behavior when you change the number of poles on a circuit row. Now, all affected rows have their VA/Amps values cleared when the number of poles is changed. An exception to this is when the load type is motor. In that instance, the VA/Amp values are recalculated based on the HP or kW value.

In panels that have a multi-pole circuit that is a Load Type of Sub-Panel, all VA/Amp cells are now unavailable for entry.

Also, if you change the number of poles at the bottom of a panel spreadsheet and there are not enough rows for the number selected, you will receive a warning to enter a valid number for the rows available.

Phases in the Same Row

Note that in versions of EasyPower prior to 10.2, it was possible to enter the load values on the same row. EasyPower allowed this and interpreted the values in the appropriate phases. Beginning with version 10.2, the values need to be put into the correct phase. If you open an older database and look at the panel schedule, you may find values in the same row in red. To correct this, simply delete the red text and type the value into the proper row.

Figure 10: Load Values in Incorrect Phases

See the Help file Panel Row Behaviors for details.

Simplified View Changes

The name of the View on the Description tab of the Panel data dialog has changed from Simplified - 3 Phase to Simplified.

You can now enter load values in the VA and Breaker Amps columns in the Simplified view, and the load value you enter is automatically added to the proper phase.
