Generator kVA for small site use: a plain-English check
Estimate generator hire size by adding watts, startup surge and safe outdoor placement requirements.
Quick answer
Generator choice starts with what runs at the same time. Motors, pumps and power tools may need extra startup allowance; heaters and kettles can be far larger loads than expected.
Checks before hire
- List watts for each appliance or tool
- Separate running load from startup surge
- Check voltage/outlet and lead requirements
- Keep the generator outdoors with exhaust clear
What to tell the hire desk
Describe the job, material, scale, access and what would make you stop. That gives the supplier a better route to the right machine, consumables and PPE than asking for a tool name alone.
Stop condition: Stop if anyone plans indoor use, medical/critical equipment, unknown wattage, or high-surge loads without supplier advice.
