GENERAC RG04524GNAX Protector Series 45 kW Standby Generator

That's exactly what the RG04524GNAX is built for. It's a 45,000 watt Protector Series standby unit wired 120/208V three phase, rated at 156 amps. If your building runs single-phase 120/240, this is the wrong unit and you need a single-phase Protector model instead. Check the service on the panel before ordering, because three-phase and single-phase generators are not interchangeable at the transfer switch.

The enclosure measures 76.8 in long, 35 in wide and 46.1 in high, so the concrete pad has to cover better than six feet by three feet before you add the code clearances your AHJ requires around it. The unit weighs 1,260 lbs assembled, which rules out setting it by hand: plan on equipment to place it and a pad poured to carry that load.

ETL Listed, UL Listed and CSA Certified, all three, which is what an inspector or a facility spec will normally be looking for on a permanent standby set. That covers the unit itself; the transfer switch, the fuel piping and the disconnect are separately approved items on the permit.

Yes. True Power technology holds total harmonic distortion under 5 percent, which is the threshold that matters for computers, medical equipment, elevator controls and variable frequency drives. Anything below 5 percent THD is generally accepted as clean enough for electronic loads that would otherwise need a separate conditioner.

Mobile Link connectivity is standard on the Protector Series, so the RG04524GNAX reports status to a phone, tablet or PC from anywhere. For a property manager running several buildings, that means you see a failed weekly self-test on the app instead of finding out during the next outage. The Evolution controller on the unit also carries a two-line multilingual LCD with USB flash capability for firmware and settings.

Quiet-Test runs the mandatory weekly exercise at a reduced RPM rather than full speed, so the self-test is noticeably quieter than a load run. The interval is programmable, weekly, bi-weekly or monthly, which lets you push the exercise to a time that suits tenants or a hospital shift change instead of accepting a fixed schedule.

Generac RG04524GNAX, Protector Series, 45 kW at 120/208V three phase. Generac's model coding runs the kW rating into the number, so RG045 is the 45 kW set; adjacent RG models in the same series are different outputs or different voltage configurations. Quote the full RG04524GNAX string when ordering so you don't land on the single-phase or 240V sibling.

The frame is steel, finished in grey. It's an outdoor standby enclosure meant to sit on a pad in the weather. In coastal or heavily de-iced environments, steel wants the finish kept intact, so plan on inspecting the enclosure at the same interval as the oil and filter service rather than leaving it alone between outages.

Country of origin on the RG04524GNAX is the United States. For public agencies, schools and healthcare procurement working under domestic-preference language, that's the line item the purchasing office asks for, and it applies to the generator unit itself.
