Free planning tool
Build a simple equipment schedule, then see the running load, starting allowance and the next common generator size. It is a planning brief, not an electrical design.
The estimate uses a 0.8 power factor, 25 percent running headroom and one largest motor-start allowance. Enter nameplate watts where available; presets are planning values, not a substitute for the supplier's equipment schedule.
Planning size
5 kVA
Selected equipment draws about 2.7 kW while running. The sizing target is 4.2 kVA after headroom and the largest starting load.
Scale shown to 30 kVA
Planning estimate only. A licensed electrician or generator supplier must confirm phase, outlets, distribution, earthing, cable runs, fuel and equipment nameplates.
Presets get an early quote moving, but the equipment arriving on site decides the real load. Ask every caterer, band, bar and amusement supplier for watts, phase and outlet details before the distribution plan is signed off.

The event generator guide covers kW to kVA, cable runs, weather protection and when mains power is the better option.
Generators are commonly rated in kVA while equipment nameplates often show watts or kW. This planner uses a 0.8 power factor, so 8 kW of design load needs about 10 kVA before selecting a standard hire size.
Yes. It compares a 25 percent running-headroom result with the running load plus the largest selected motor-start allowance, then uses whichever is higher. Actual equipment nameplates and starting methods still take priority.
The result is for planning a supplier conversation. A licensed electrician or generator supplier must confirm phases, outlets, distribution boards, earthing, cable protection, fuel and the actual equipment schedule.
