GENERAC RG08045JNAX Protector 80kW Automatic Standby Generator 120/240 3Ø

The RG08045JNAX is a 120/240 volt three phase unit rated 80,000 watts standby, with a 200 A current rating. That phase configuration matters: three phase 120/240 is a less common service than single phase, so confirm your building service and transfer switch match three phase before you commit. If your site is single phase 120/240, this is the wrong model number in the Protector line.

Plan the pad around a footprint of 97 inches long by 38 inches wide, with the enclosure standing 49 inches tall. Generac rates the Protector liquid-cooled units for installation as close as 18 inches from a structure, which is what makes them workable on tight lot lines. Add your own clearance for service access and any local separation rules on top of that.

Both. The unit is configured for liquid propane or natural gas, using a dual-valve ultra-low pressure fuel delivery system. Your gas contractor sizes the supply line for the full 80kW load, and the fuel selection is set at commissioning rather than being a different part number.

It weighs 2,022 lbs assembled. That is a crane or forklift set, not a two-man lift, and the concrete pad has to be poured for it. Aluminum enclosure keeps the weight down relative to steel at this output, but you still want equipment on site the day it lands.

Motor starting is one of the things this line is built around. Generac rates the Protector for heavy motor load such as air conditioning and process equipment, starting cleanly on initial startup. Output is held under 5% total harmonic distortion, so sensitive electronics and controls on the same bus are not being fed dirty power while the generator carries the building.

Yes. Mobile Link connectivity is standard on Protector Series models, so generator status can be checked from a phone, tablet or PC anywhere. On the unit itself, the Evolution controller with its LCD display is readable without opening the enclosure, and it tracks maintenance intervals. For a portfolio of sites that is the difference between a monthly drive-by and a dashboard.

Order model RG08045JNAX. That designation is the 80kW Protector automatic standby set at 120/240 three phase. Distributors quoting against a drawing should match the full string, since the Protector line uses neighboring numbers for other outputs and voltage configurations.

Quiet-Test self-test mode runs the engine at a lower, quieter RPM for either a five or twelve minute test, and it can be scheduled weekly, bi-weekly or monthly. It also burns less fuel than a full-speed exercise. For multi-family or hospitality sites, scheduling that twelve minute run outside quiet hours usually settles the noise complaint issue.

The enclosure is corrosion-resistant aluminum with Generac's RhinoCoat powder-coated finish, in a bisque color chosen to blend into landscaping. Aluminum rather than steel is the reason these units are specified near salt air. The engine and unit are built in the United States.
