- Global definition of arc flash analysis data eliminates the need to specify this information in each bus
- Global definition of working distance, bus gaps, approach boundaries, & voltage-rated glove classes
- Specify Arc Flash Analysis Data based on IEEE 1584 2002 or user-defined values
- Globally select Shock Hazard Analysis Data based on NFPA 70E 2004, NFPA 70E 2009 or user-defined settings
- Globally change the voltage-rated glove class settings given by ASTM D 120-02a Standard for voltage-rated protective gloves
- Updates to arc flash calculation data can be made globally without having to modify each bus editor individually

| Motor Contributions & Low Voltage Equipment Handling |
| ETAP arc flash analysis software makes it easier to specify arc flash analysis data that should be applied to low voltage equipment such as motors and transformers based on NFPA 70E 2009 & IEEE 1584. |
- Consider motor fault current decay for arc flash analysis
- Automatically exclude small motor contributions entirely from the arc flash analysis
- The arc flash analysis software automatically adjust the arc fault current based on the decaying motor contributions and determines the effect on the energy and protective device response.
- User-definable cycle (time) for motor contribution to allow better modeling of motor time constants for the arc flash calculation.
- The arc flash analysis program automatically applies the NFPA 70E equations when the bolted fault current and voltage are outside the range permitted to obtain arc flash analysis results.
- Automatically identify & exclude transformers with relatively low voltage & size (kVA)
- Automatically assign arc flash hazard category to these types of equipments based on fault current ranges
