The ANZ standard specifies the equation for voltage drop calculation as follows:
Vd = (L * Id * Vc) / 1000
Where:
Vd = actual voltage drop, in volts
Vc = the millivolt drop per ampere-metre route length of circuit
L = route length of circuit, in metres
Id = the current to be carried by the cable, in amperes
|
Note: For single phase (phase to neutral) loads Vc = Vc * 2/ 3

The result of this calculation can be found in Sizing Result tab as shown below.
