This Protector Diesel RD Series model uses a 2.5L engine and is listed with a larger tank for longer run time. The supplied product data identifies this model as diesel-fueled and notes that 30kW and below diesel models are CARB emission compliant in California and Los Angeles, do not require a catalyst, and are also emissions compliant in Massachusetts. Generac’s official RD02025 extended-tank page supports the broader 20kW diesel, 1800RPM extended-tank platform, while dealer sources cross-check RD02025ADAL as the 120\/240V single-phase extended-run model. Buyers should confirm load sizing, transfer equipment, fuel storage requirements, local code requirements, and installation planning before ordering.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003e20kW Diesel Backup Power for 120\/240V 1-Phase Applications\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe RD02025ADAL is built for standby generator projects where 20kW output, diesel fuel, and 120\/240V single-phase service are required.
