The C12D6RE is $21,992.00 for the equipment, the same at every voltage it is offered in. Freight is not charged at checkout: it is quoted per shipment, and we confirm it with you by phone before anything is booked. Sales tax is calculated at checkout from the delivery address. No installation is included or required to run it as a stand-alone generator. ### Can we buy the C12D6RE for a rental fleet? Yes. This is a Cummins rental package, built for fleet use: a lockable enclosure, onboard fluid containment and controls designed for rental operators. Rental companies and commercial buyers can order online or by phone. Tax-exempt purchases require a valid Texas resale or exemption certificate. Without one on file, sales tax is charged at checkout. To buy tax-exempt, provide your certificate before ordering by calling (214) 957-4307; online checkout cannot accept a certificate. Orders for several units are also easier to arrange by phone. ### Which voltage should I choose? The C12D6RE is a 120/240 1Ph unit, which covers standard 120 V and 240 V tools, job-site panels and single-phase loads. It is not offered in a three-phase build. ### How long will the C12D6RE run on a tank? The onboard tank holds 26 gallons, which Cummins rates at about 29.5 hours at 75% of prime load. At full standby load it burns 1.28 gallons an hour. ### What do I need to tow the C12D6RE? It weighs 1,801 lb dry and 2,017 lb with a full tank, about 1 tons, on a single-axle trailer. Check your tow vehicle and hitch against the wet weight, not the dry weight. ### Can the C12D6RE power a building? Yes, but not by plugging it in. Connecting a generator to a building's wiring needs a properly rated transfer switch or generator docking station installed by a licensed electrician, so the generator cannot back-feed the utility line. That work is not sold with the equipment. In Dallas-Fort Worth we quote it separately after a site survey.
