GENERAC RG02224ANAX RG02224ANAX - 22/22 kW, 1800rpm, Alum Enclosure, SCAQMD Compliant

Plan the pad around a footprint of 62.2 inches long by 30.6 inches wide, with the unit standing 38.6 inches high. The generator weighs 905 lbs, so the slab and any lifting plan need to carry that. Crated/assembled figures run larger at 43.5 inches high, 35.3 inches wide and 35.25 inches deep, which is what matters for getting it through a gate or down a side yard on the way to the pad.

Size the gear to 92 A at 120/240 V single phase. That is the current the RG02224ANAX puts out at its 22,000 W rating, so a 100 A transfer switch and service-rated overcurrent protection is the class of equipment this unit lands in. Run the load calc against 92 A, not against the kW headline, when you are deciding whether to transfer the whole panel or a selected-circuit subpanel.

Yes, that is the reason to pick this one. The RG02224ANAX carries the standard aluminum all-weather enclosure, which Generac calls out specifically for salt-air and coastal locations because aluminum does not rust the way a steel housing does. The frame underneath is steel and the enclosure finish is grey. If the unit is going within sight of the water or on a roof deck taking salt spray, the aluminum housing is the right call.

Either one. The RG02224ANAX ties into the building's existing liquid propane or natural gas supply and starts automatically within seconds of a power loss, so there is no fuel tank to fill or rotate. Confirm your gas line can carry the flow to the unit before you set it; that sizing is done by the installing plumber or gas fitter off the meter and run length.

The RG02224ANAX is the SCAQMD compliant build of the 22/22 kW Protector, which is why the model exists as a separate part number from the standard 22 kW. If the job is in the South Coast air district, order this exact MPN, RG02224ANAX, rather than a non-compliant equivalent, because the permit will be pulled against the model on the nameplate.

Single phase, 120/240 V. If your building service is 208 V three phase, which is common on commercial and multi-family panels, this is the wrong unit and you need a three-phase Protector instead. Check the service before ordering; the phase is not field-changeable.

1800 rpm is the slower, longer-lived engine speed, and it is what separates the Protector line from air-cooled residential units that spin at 3600. The RG02224ANAX also runs its weekly self-test at 1800 rpm under Generac's Quiet-Test, which burns less fuel and puts less hours-equivalent wear on engine and alternator. For a property manager with a unit near occupied bedrooms or a neighbor's lot line, the weekly exercise is the noise event people actually complain about, and this is the unit that keeps it quieter.

It is UL Listed, ETL Listed and CSA Certified. That covers the listing questions an inspector or a facilities spec typically raises on a permanently installed standby set, and the CSA certification means it is acceptable on Canadian work as well as US.

True Power Technology holds total harmonic distortion under 5 percent on the RG02224ANAX, which is the number that matters for variable speed drives, medical equipment, servers and modern appliance boards. Under 5 percent THD is the threshold most sensitive-electronics specs are written to, so this set can carry that load rather than being limited to motors and resistive heat.

Mobile Link comes standard on the RG02224ANAX and every Protector Series unit, so status is visible from a phone, tablet or PC anywhere. For a property manager or MRO group running standby power at several sites, that means you see a failed self-test or a fault on a vacant building without sending someone out. At the unit itself the Evolution Controller gives a two-line multilingual LCD with backlit color-coded buttons, readable through an external viewing window so a tech can check state without opening the enclosure.

Built in the United States, and it does not carry a California Prop 65 birth-defect chemical warning. That combination matters on government, education and healthcare procurement where domestic-origin preference and Prop 65 disclosure both get asked on the bid form.
