What the numbers mean
At 17,000 running watts
on its best fuel, this unit is sized for whole-house coverage on a typical 200 A home, subject to a load calculation by a licensed electrician.
Runs on natural gas, propane — expect lower output on propane (roughly
10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the
published per-fuel ratings.
Estimated fuel cost for 24 h at ~50% load: about $59 on natural gas at
national average prices (assumptions).
Permanently installed unit: sizing, gas-line capacity, placement clearances, and
the transfer switch are a job for licensed installers under local permits.
What can the Cummins QuietConnect RS17A 17kW run during an outage?
With 17,000 running watts on its best fuel, the Cummins QuietConnect RS17A 17kW is sized for whole-house coverage on a typical 200 A home, subject to a load calculation by a licensed electrician. Add up your actual loads with a sizing worksheet — the bands here are rough guidance, not a load calculation.
What does the Cummins QuietConnect RS17A 17kW cost to run for a day?
Roughly $59 for 24 hours of continuous operation at about 50% load on natural gas, at national average fuel prices. The assumptions behind this estimate are documented on the methodology page; your fuel price and load change the figure.
Does the Cummins QuietConnect RS17A 17kW start automatically?
Yes — home standby generators monitor utility power and start themselves when it fails; pairing it with an appropriately sized automatic transfer switch (sold separately for some configurations) completes the automatic changeover.
