Build List Identification Guide
The engine serial number (ESN) for this model begins with the prefix DGBH, which Perkins' official engine number records assign specifically to the 4008-30TAG2 (distinct from DGDH, used for 4008-30TAG3).
Please confirm your engine's Build List and ESN before requesting a formal quotation, as specifications and part compatibility can vary between builds. Note that the 4008-30TAG2 should not be confused with the earlier 4008TAG2/4008TAG2A line, which uses a different Build List and rating structure.

FAQ
Q1. Is the 4008-30TAG2 the same engine as the 4008TAG2 or 4008TAG2A?
No. The 4008-30TAG2 belongs to the current 4008-30TAG family and uses Build List prefix DGBH, while 4008TAG2/4008TAG2A is an earlier, separate product line with different ratings and part numbers. Always confirm the exact model designation and Build List before ordering parts to avoid cross-line mismatches.
Q2. How do I confirm my engine is a genuine 4008-30TAG2?
Check that your engine's serial number carries the DGBH prefix, which corresponds specifically to the 4008-30TAG2 in Perkins' official engine number records. Providing your Build List and ESN allows us to verify this before quoting.
Q3. What is the standard service interval and fuel consumption for the 4008-30TAG2?
The engine uses 500-hour service intervals for oil and fuel under all operating conditions. At Prime/DCP rating, fuel consumption is approximately 202 g/kWh at 110%, 100%, and 75% load, and 205 g/kWh at 50% load.
Q4. Why do different generator sets quote different kVA outputs for the same 4008-30TAG2 engine?
The engine's own Prime/Standby ratings are fixed, but the kVA figure a genset manufacturer advertises depends on the alternator selected and its derating — this is why you may see 1000kVA, 1010kVA, or 1100kVA quoted for sets built around the same engine. When sourcing or reselling, confirm the actual engine Build List and ESN rather than relying on the genset's advertised kVA alone.
Q5. Is the 4008-30TAG2 still in current production and available for sourcing?
Yes, the 4008-30TAG2 remains part of Perkins' active 4000 Series lineup for the standby power generation sector. As a first-tier Perkins distributor partner, we maintain in-stock inventory to support faster delivery against this demand.
Q6. What Prime and Standby output range does the 4008-30TAG2 support?
At 1500rpm, the engine delivers 851 kW net (1010 kVA) at Prime/DCP rating and 947 kW net (1125 kVA) at Standby rating.
Q7. Does the 4008-30TAG2 support 1800rpm (60Hz) operation?
No, the 4008-30TAG2 is only produced as a 1500rpm (50Hz) engine; it is not available in a 1800rpm variant.
Q8. What applications is the 4008-30TAG2 typically used for?
This engine is commonly specified for prime and standby generator sets in manufacturing facilities, hospitals, and data centres, where its power-to-weight ratio and load acceptance suit continuous or often-on duty cycles.
