Motor Starting Load Worksheet
Combine one starting appliance with other loads already running.
Open this toolStarting one motor while other loads run can demand more power than the normal running total.
Enter the starting appliance and your measured or specified multiplier, then add the other active loads. Review the total against an inverter's actual surge specification.

How to use
- Enter starting appliance running power, starting power multiplier and starting power factor assumption.
- Enter other running power, other load power factor and surge allowance.
- Select Calculate result. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why use this tool
Separating one start from the already running schedule avoids treating every appliance as starting at once.
Before relying on the result
Multiplier is an entered assumption, not a motor specification. Check measured starting demand and inverter surge duration. The result is not proof an appliance will start.
Tool limitations
Multiplier is an entered assumption, not a motor specification. Check measured starting demand and inverter surge duration. The result is not proof an appliance will start.
Questions
Does a matching surge figure guarantee the motor will start?
No. Surge duration and actual motor behaviour matter. Confirm the requirement using equipment specifications and appropriate measurements.
What should I check before using Motor Starting Load Worksheet?
Check Starting appliance running power, Starting power multiplier, Starting power factor assumption and Other running power. Use the exact units shown beside the controls and replace any example values with your own inputs.
