Range: 0–10,000 count

Enter the number of lighting points on the final circuit.

Range: 0–100,000 VA

Enter the electrical input allowance per lighting point.

Range: 0–100,000 kW

Enter the connected fixed load assigned to this circuit.

Range: 0–100 %

Enter the selected factor for simultaneous operation of the fixed load.

Range: 1–100,000 V

Use the phase-to-neutral voltage for this final-circuit estimate.

Range: 0.01–1

Use the expected circuit power factor for converting VA to current.
