GENERAC RD02025JDAL Protector Series 20 kW Diesel Standby Generator - 3 Phase 120/240 V, Extended Tank

Plan the pad and the rigging around 81 inches long by 31 inches wide by 65 inches tall, with the unit weighing 1,465 lbs dry. That footprint includes the sound attenuated aluminum enclosure and the extended base tank, so the concrete pad needs to carry the full 1,465 lbs plus fuel. At that weight it is a crane or forklift set, not a two-man lift.

Output is 167/84 A at 120/240 V. The 167 A figure is the 120 V leg rating and 84 A the 240 V rating, so size the transfer switch and feeder conductors to the value that matches how you are landing the load. Confirm the switch is rated for the full 167 A before you order it as a package.

Diesel only. The RD02025JDAL is a diesel Protector Series unit with an extended base tank built into the skid, so there is no gas piping to run, no LP tank to set, and no fuel conversion kit. If the site has natural gas or LP service and no diesel delivery, this is the wrong unit for the job.

It is. The generator set carries UL/CUL 2200 listing and the base tank is listed to UL/CUL 142. The package is also ETL Listed, UL Listed and CSA Certified, which is usually what an AHJ or a hospital or school facilities inspector wants to see on a sub-base fuel tank installation.

It runs an isochronous electronic governor, which holds engine speed and therefore frequency constant from no load to full load rather than letting it droop. That is the governor type you want behind elevators, UPS front ends, variable frequency drives and IT rooms at this 20 kW size.

Mobile Link connectivity is standard on Protector Series units including this one, so status can be checked from a phone, tablet or PC from anywhere. On the unit itself there is a two line multilingual LCD Evolution controller in English, Spanish, French and Portuguese, with an external viewing window so you can read generator status and breaker position without opening the enclosure. For a property manager running several sites, that means you are not driving out to read a panel.

The enclosure and frame are both aluminum with an aluminum finish, which does not rust the way a steel housing does in salt air or a wet climate. The enclosure is also sound attenuated, which matters when the set is going next to occupied units or near a property line with a noise ordinance.

Specify Generac RD02025JDAL. That designation covers the 20 kW diesel Protector Series set at 120/240 V with the extended base tank and aluminum sound attenuated enclosure. Put the full model on the submittal, since the Protector diesel line runs several kW ratings and tank configurations under similar numbering.

A smart battery charger is included as part of the package, so the starting battery stays maintained while the set sits on standby and is ready for the exercise cycle. The battery itself is a separate item to source, along with diesel fuel, engine oil per the manufacturer's start-up requirements, and the transfer switch.

Country of origin is the United States, and it is not flagged as containing chemicals that cause birth defects under California Prop 65. That is the pair of data points government and institutional procurement usually needs for a domestic preference or a Buy American clause review.
