What it actually decides.
An event generator is a towable or truck-mounted diesel set that supplies the show where building power is absent or insufficient. On outdoor work it is normal rather than exceptional.
Sizing is where the money is wasted in both directions. Undersized is obvious. Oversized is the quieter problem: a diesel engine running at a small fraction of its rating does not reach proper operating temperature, and unburned fuel and carbon accumulate in the exhaust. The condition is called wet stacking and it degrades the machine. A generator sized honestly against the calculated load, rather than against the biggest number anybody said out loud, runs better.
The word whisper is worth untangling, because it is a manufacturer’s product name that has become a generic request. What is actually being asked for is a sound-attenuated set — an acoustically lined enclosure with silenced intake and exhaust — and the specification that means anything is the published decibel figure at a stated distance, not the adjective.
Siting is the other half. Exhaust goes downwind of the audience and away from any air intake. Noise is positioned relative to the stage and to whatever the neighbours are, which outdoors is usually a permit condition rather than a courtesy.
Grounding and bonding are not optional and are not always the same as a building supply. Where a generator and house power both feed the same structure, their grounds have to be bonded together.
