Calculation Methods and Formulas

This section describes some of the calculation methods used by Design Master Electrical.

Concepts

📄️ Fault Calculation Method

The fault calculations are based upon IEEE Std 242-2001: IEEE Recommended Practice for Protection and Coordination of Industrial and Commercial Power Systems.

📄️ Voltage Drop Calculation Method

Voltage drop calculations are based upon the load, power factor, and other properties of the device(s) and connected wires.

📄️ Wire Sizing Calculation Method

The wire size for a given ampacity is set in the Wire Sizing command. This section describes the NEC values used and sizes provided for the default wire sizing.
