150-300 kW Towable Diesel Generator

Select the 150-300 kW class when total connected load, including startup inrush for motors and HVAC, exceeds the capacity of the 60-150 kW Towable Diesel Generator but does not require the 300-600 kW Towable Diesel Generator tier. This range suits temporary utility service for mid-sized commercial buildings, outdoor events with full catering and lighting infrastructure, and industrial sites running pumps, conveyors, or welding equipment. For peak demands above 275 kVA or mission-critical applications requiring N+1 redundancy at the 200+ kW level, the 300-600 kW class offers greater headroom and often includes integrated switchgear.

• Temporary service for a 50,000-square-foot office building during utility transformer replacement
• Primary power for a remote pump station dewatering a large excavation or tunneling operation
• Backup power for a manufacturing facility maintaining CNC machines and welding bays during a planned outage
• Outdoor festival with multiple stages, sound reinforcement, food-service trailers, and site lighting
• Data center or telecom switching facility requiring uninterrupted load during a scheduled utility cutover
• Construction project supplying power to multiple tower cranes, batch plants, and site offices

• Install ground rods and verify bonding before energizing loads; consult NFPA 70 (National Electrical Code) Article 250 for grounding and Article 445 for generators
• Maintain clearances around exhaust outlet: typically 10-15 feet from combustible materials and building air intakes to prevent carbon monoxide intrusion
• Secure trailer with wheel chocks and stabilizer jacks; ensure firm, level footing to prevent vibration-induced fuel or coolant leaks
• Implement lockout/tagout procedures during refueling or maintenance; never open fuel caps or service filters while engine is running or hot

• Tandem-axle trailer requires a Class 7 or Class 8 truck, heavy-duty pickup (F-550/5500-class), or tractor with appropriate pintle hitch or fifth-wheel adapter
• Total weight typically 8,000-15,000 pounds; verify road permits and bridge ratings for over-dimension or overweight loads in some jurisdictions
• Site placement may require forklift or small crane if terrain precludes direct towing to final position

• Units consume ultra-low-sulfur diesel (ULSD) at rates of 10-20 gallons per hour under full load; plan for daily or twice-daily refueling on extended-duration jobs
• Output via cam-lock, pin-and-sleeve, or panel-mount circuit breakers; distribution typically handled by separate power-distribution panels or temporary switchgear
• Generator controller monitors voltage, frequency, and engine parameters; many models include remote monitoring via cellular or satellite telemetry
