Independent energy/ CALCULATOR

Generator running & starting load

Check one documented motor start against other running loads.

Exclude the motor entered below.
From equipment documentation or measurement.
Total starting watts, not additional starting watts. Confirm with manufacturer.
Combined running requirement

1,300 W

Combined starting requirement

2,500 W

One motor start only. Does not select equipment or account for VA, voltage dip, start duration, multiple simultaneous starts or derating. Confirm the combination with the generator supplier.

FROM ESTIMATE TO ACTION

Use the result, not just the number.

01

Verify the inputs

Measure or document each input. If a value is only an estimate, record its source and test a conservative alternative.

02

Keep the calculation traceable

Save the input link or copied result together with the date, units and assumptions. A number without its inputs cannot be checked later.

03

Confirm the decision

Compare the estimate with the related guide, current product data and requirements that apply at your location before buying or building.

Inputs to verify

Other loads already running (W)
Exclude the motor entered below.
Motor running demand (W)
From equipment documentation or measurement.
Motor total starting demand (W)
Total starting watts, not additional starting watts. Confirm with manufacturer.
