How is this calculated?

We apply a standard 0.8 power factor (typical for mixed inductive/resistive loads) and a 20% safety margin to handle motor start surges and future load additions. This gives a conservative estimate suitable for sizing.

For precise engineering calculations, contact our sales team for a load survey.
