01How should I size a diesel generator for a project?
Start with the simultaneous running load and largest starting event, then add the operating pattern and site conditions. Final sizing should be checked against the exact generator-set data rather than a generic percentage allowance.
02Does an enclosed diesel generator automatically count as silent?
No. An enclosure is visible construction; a silent or quiet claim needs a defined test condition and model-specific acoustic evidence. Ask for the applicable noise data before using that claim in a tender or listing.
03When do phase and frequency need to be confirmed?
They need to be confirmed before model selection is finalized. State the destination country, load voltage, frequency and single- or three-phase requirement in the first project brief.
