Common Mistakes to Avoid
Sizing errors usually come from choosing the wrong workflow depth for the project and from under-specifying starting and load assumptions.
Under-specifying starting surges and safety margins
Using only connected load totals without a starting allowance approach can lead to undersized generator capacity for motor-heavy sites. GeneratorSizing.com Calculator includes surge and safety margin adjustments, and Brilltech Diesel Generator Sizing provides motor start-up allowance inputs to support more realistic diesel set capacity selection.
Choosing a calculator that only supports a narrow sizing use case
Using an early-stage quick-sizing tool for heavy documentation deliverables can produce outputs that lack the document-aligned structure needed for formal review. TÜV SÜD Power Plant Sizing Software targets documentation-oriented sizing outputs, while Neuro Generator Calculator focuses on fast preliminary sizing from load and power factor inputs.
Feeding inconsistent load totals and power factor assumptions
Many generators sizing tools require disciplined electrical input collection because accuracy depends directly on load and electrical assumptions. E‑Size Generator Calculator and Generator Calc (Load and KVA Estimator) both emphasize that sizing outputs depend heavily on correct connected load and assumptions.
Relying on manual worksheet work without a structured load aggregation step
Manual spreadsheet or worksheet assembly increases the chance of missing circuits and mismatching assumptions between totals and starting power logic. Exactal Electrical Estimating reduces omissions by organizing electrical scope into workpacks, while Diesel Generator Sizing and Load Budget Templates provides visible formulas but still depends on correct input validation.
