The IEEE 1584 empirically derived model was chosen for arc flash analysis due to the model's capability to accurately account for a wide variety of setup parameters including:
* open and box equipment configurations
* grounding of all types and ungrounded
* gap between conductors of 3 to 152 mm.
* short circuit currents in the range of 700A to 106kA
* system line voltages in the range of 208V to 15kV
* working distances from 10 to 80 inches
For cases where voltage is over 15kV or gap is outside the range of the model, the theoretically derived Lee method can be applied and it is included in iAFA V1.0
The arc flash software takes equipment configuration, gap between electrodes, grounding type, short circuit fault current value and system voltage on input, and determines arcing fault current at potential point of fault.
For protective devices operating in the steep portion of their time-current curves, a small change in current causes a big change in corresponding operating time. Incident energy is linear with time, and consequently arc current variations may have a big effect on incident energy. The IEEE 1584 proposed solution is to make two arc current and energy calculations: one using the calculated expected arc current and another one using a reduced arc current that is 15% lower.
The arc flash software enables calculations for both of the above considered cases. The iAFA arc flash software predicts arcing fault current for a given configuration and amount of the available 3-phase short circuit current. Next, the incident energy, arc flash boundary, shock protection boundaries and level of personnel protective equipment are determined based on equipment configuration, selected upstream protection device ratings and working distance.

The Calculator determines grounded and ungrounded loads for general lighting, fastened (or fixed) appliances, dryers, cooking appliances, heating and A/C units, and the largest motor. All numeric entries are in Volt-Amperes (VA). The calculated loads are compiled to determine the total service load for a single-family dwelling.
After the service load is calculated the Calculator determines the size of the service-entrance conductors required for the dwelling. Proper sizing of the conductors is required to ensure the safety and efficiency of the service.
The Calculator is designed to be an aid to electricians in electrical load calculations and is not intended to replace Article 220 of the NEC® or the NEC® as a whole.

Simple point-to-point short circuit fault current calculations are carried out using Ohm's law and equipment resistance values. To determine fault current at various locations within power system, the system characteristics such as available short circuit value at service entrance, line voltage, transformer KVA rating and percent impedance, conductor characteristics are utilized.
The calculations become more complicated when resistance values are replaced with an impedance values. For instance, transformer ratio of reactance to resistance (X/R) is used along with transformer percent impedance to determine X and R values on a per unit bases. Similarly, the impedance for conductors within the electrical system are also broken down into X and R components of the impedance.
The peak asymmetric fault current is also determined by X/R ratio. The total asymmetric current is a measure of the total DC component and the symmetrical component. The asymmetrical component decays with time and will cause the first cycle of a fault current to be larger in magnitude than the steady-state fault current. Also, the decay of the DC component depends on the X/R ratio of the circuit between the source and the fault.
Knowing the fault X/R ratio is essential when selecting electrical and protection equipment. For example, all low-voltage protective devices are tested at predetermined X/R ratios. If the calculated X/R ratio at any given point in the electrical distribution system exceeds the tested X/R ratio of the overcurrent protective device, alternate gear with adequate X/R rating should be considered or the device effective rating must be reduced.
