Cummins generator cost
Cummins home standby generators are sold through dealers, which provide a quote for the unit. Install costs stay the same for any brand of that size.
At US wages, a 22 kW unit adds $3,800 to $8,700 for the electrician, gas line, pad and permit, regardless of the Cummins quote. Wage source: BLS, May 2025.
