Generac RG04524KNAX – Frequently Asked Questions

1) Can I buy the Generac RG04524KNAX in California or Massachusetts?
No. The RG04524KNAX 45 kW Protector standby generator is not sold in California or Massachusetts, and it is flagged as a restricted item. For jobs in those two states you need a model built to their emissions rules instead.
2) What voltage and current does this 45 kW Generac standby put out?
The RG04524KNAX is a 3-phase unit at 277/480 V, rated 45,000 watts, with a current rating of 68 A. If your building service is 120/240 single phase or 120/208 three phase, this is the wrong unit, and you need a different voltage configuration of the Protector Series.
3) How big a pad do I need to pour for this Generac 45 kW generator?
Plan the pad around the enclosure footprint: 76.8 in long by 35 in wide, 46.1 in high. It weighs 1,260 lbs, so the pad and any rooftop or structural location has to carry that load plus fuel and service access clearance on all sides.
4) Does this Generac run on natural gas or propane?
Both. The RG04524KNAX is an LP/NG unit, so it can be set up on either natural gas or liquid propane, and it produces 45 kW on either fuel (45/45 kW). The gas supply has to be sized for the full load, which is where most installs go wrong.
5) Is the Generac RG04524KNAX listed for a commercial standby installation?
It is UL Listed, ETL Listed and CSA Certified. That is typically what an inspector or institutional spec wants to see on a permanently installed standby set. Country of origin is the United States, which also satisfies many public-agency sourcing requirements.
6) Is the enclosure on this unit steel or aluminum, and will it hold up outdoors?
The housing is an aluminum enclosure in a grey finish, with a steel frame underneath. Aluminum is the usual choice for coastal and humid sites because it does not rust through the way painted steel skin does.
7) Will this generator run sensitive electronics and building control gear cleanly?
Yes. The unit uses Generac True Power technology, holding total harmonic distortion under 5 percent, which is the threshold that matters for elevator controls, VFDs, IT loads and medical equipment on a standby bus.
8) How does weekly exercise work on this unit, and can I monitor it remotely across a portfolio?
The Protector Series runs its self-test at a reduced, quieter RPM under Quiet-Test, and the schedule can be set weekly, bi-weekly or monthly, which helps on multi-family and tenant-occupied sites. Mobile Link remote monitoring is standard, so status can be checked from a phone, tablet or PC without a site visit.
9) What controller comes on this Generac Protector generator?
It ships with the Evolution controller: a two-line multilingual LCD with color-coded backlit buttons, USB flash capability, smart battery charging and voltage adjustment. The USB port is what your service tech uses to load firmware and pull data.
10) Does this generator carry a California Prop 65 chemical warning?
No. The RG04524KNAX is recorded as not containing chemicals known to cause birth defects under California Prop 65. Note separately that the unit itself is not sold into California.
