Applications
The same kW figure means different things on a job site, in a venue and in a driveway. Start from the application.
Job-site power is a scheduling problem as much as an electrical one. The unit has to arrive, fit, connect and keep running while trades come and go.
Typical sizes: 20-60 kW for small crews, 60-150 kW once HVAC, cranes or pumps are involved
Event power is judged by what the audience does not notice. Noise, flicker and a dropped feed are the failures people remember.
Typical sizes: 5-25 kW for small events, 60-150 kW for festival sites with vendor rows and staging
Outage rentals are different in one way that matters: everyone in the affected area wants the same equipment on the same afternoon.
Typical sizes: 5-12 kW for essential home circuits, 20-60 kW for whole-home or small business continuity
Facility power is planned work. The equipment matters less than the switchover sequence, the documentation and who is accountable for each step.
Typical sizes: 150-500 kW for building standby, 500 kW and above containerised for plant or campus loads
RV power comes down to one appliance. If the air conditioner has to run, everything else about the choice follows from that.
Typical sizes: 2-4 kW without air conditioning, 3.5-7 kW to start a rooftop air conditioner
