Label Variables

Much of the text that appears on an arc flash label originates from the Arc Flash Hazard Report or the equipment data dialog boxes in EasyPower. These values are referred to as variables in the label designer, and they can be included in text items or used to change the appearance of the label under different conditions.

Variable Name

Hazard Units

Units for incident energy. For example, Cal/cm2.

Incident Energy

Incident energy at the working distance.

Is Base Case

Displays Yes for base case and No for scenario.

Kilo Volts

Label Comments

Optional comments entered by the user when printing labels. Equipment specific comment entered in Arc Flash Hazard tab of the equipment dialog box. You can also enter comments in the Arc Flash Hazard Report.

Label Print Day Number

Day number of the date the label was printed. For example, for the date July 15, 2018, the number is 15.

Label Print Index

Index of the label printed for the device. Ranges from 1 to the Number of Labels to Print.

Label Print Month Name Abbreviation

Month on which the label was printed. For example, for July 15, 2018, this would be Jul.

Label Print Month Full Name

Month on which the label was printed. Example for July 15, 2018, this would be July.

Label Print Month Number

Month on which the label was printed. Example for July 15, 2018, this would be 7.

Label Print Year Number

Month on which the label was printed. Example for July 15, 2018, this would be 2018.

Limited Distance

Limited Approach Boundary as per NFPA 70E, based on equipment voltage.

Limited Distance Value

Numeric value for the limited approach boundary.

Location Description

Location of the equipment from the Location tab in the equipment dialog box.

Location Floor

Floor data from the Location tab of equipment dialog box.

Location X

X coordinate of the equipment as entered in the Location tab of equipment dialog. X can be feet, inches, meters, and so on.

Location Y

Y coordinate of the equipment as entered in the Location tab of equipment dialog. Y can be feet, inches, meters, and so on.

Maintenance

Displays On if the upstream trip device has Maintenance Mode set to on, and Off otherwise.

Momentary Bus Current in Amps

Momentary (1/2 cycle) short circuit current at the faulted bus. Value in Amps.

Momentary Bus Current in Kilo Amps

Momentary (1/2 cycle) short circuit current at the faulted bus. Value in kA.

Number of Labels to Print

Total number of labels to print for device, as specified in the equipment data dialog or Arc Flash Hazard Report.

PPE

PPE Level Text from tables in the library based on incident energy calculated. You can choose the table in Advanced Options in the Arc Flash Hazard dialog box. For comparisons it is same as PPE Class. See Arc Flash Hazard Options.

PPE Class

Ordinal value of the PPE level for the arc flash calculated.

PPE Level

For display it is the same as PPE, but it is the string value of PPE that can be compared against.

Prohibited Distance

Prohibited approach boundary with unit as per NFPA 70E.

Prohibited Distance Value

Numeric value of prohibited approach boundary.

Project Code

Project Code value entered in the File Properties dialog box.
