GENERAC RD05033JDAE 50kW Protector Diesel Standby Generator 3-Phase (120/240)

Plan the pad around a footprint of 80.8 inches long by 30.5 inches wide, with the enclosure standing 57 inches tall. The unit weighs 2,197 lbs, so the pad and the rigging both have to carry that. On a rooftop or podium deck, get the structural load signed off before delivery, because this is a crane or forklift set, not a two-man carry.

No. The RD05033JDAE is a 3-phase 120/240 V machine and it needs a 3-phase service to land on. If the building is single-phase 120/240, this is the wrong configuration and you want the single-phase version of the 50kW Protector diesel instead. Check the utility service and the existing panel before you order, because the phase configuration is not field-changeable.

The RD05033JDAE puts out 250/125 A across its current range, so the 250 A figure is what the feeders, the breaker, and the automatic transfer switch have to be sized against on the 120 V leg configuration. Transfer switch is a separate order line, it does not come with the generator.

It is UL Listed, ETL Listed, and CSA Certified. That covers the approvals an inspector or a facilities spec typically calls for in the US and in Canada, which matters if you are standardizing standby power across a portfolio that crosses the border.

Both the frame and the outer enclosure are aluminum, which is why this one gets specified near salt air and on rooftops where a steel housing would streak and rust out. It is a sound attenuated aluminum enclosure, so it also holds noise down for installs close to occupied space or a property line.

Mobile Link connectivity is standard on every Protector Series generator, so you can see generator status from a phone, tablet, or PC anywhere. For a property manager running standby power at several buildings, that is the difference between knowing a unit failed its weekly exercise and finding out during the outage. The Evolution controller also has a two line LCD with an external viewing window, so you can read status and breaker position without opening the enclosure.

It runs an isochronous electronic governor, which holds engine speed, and therefore frequency, flat as load comes on and off rather than drooping with it. That is what you want behind elevator controllers, VFDs, and IT loads. A smart battery charger is also included, keeping the starting battery conditioned between exercise cycles.

The manufacturer part number is RD05033JDAE. Generac's diesel Protector line splits by kW, fuel, and phase, and the numbers look alike, so quote the full RD05033JDAE when you order or you can end up with the single-phase or a different kW rating. Country of origin is Uzbekistan if your submittal package asks for it.

This is a diesel machine, so it runs from a fuel supply rather than a gas or propane line, and diesel standby installs need the fuel storage, the day tank arrangement, and the spill containment worked out as part of the install, not as an afterthought. If your site already has natural gas or LP at the pad, a gaseous Protector is the simpler install and drops the fuel storage and the fuel polishing entirely. Diesel earns its place where there is no gas service, or where the authority having jurisdiction wants on-site fuel for a required standby system.

The Evolution controller is multilingual, running English, Spanish, French, and Portuguese on a two line LCD. Useful where maintenance staff or a service contractor is not working in English.
