What is the typical output capacity of vehicle-mounted generators?

• A. Up to 12,000 watts
• B. Up to 5,000 watts
• C. Up to 20,000 watts
• D. Up to 50,000 watts

Answer: (A)

Vehicle-mounted generators on fire apparatus are sized to provide enough electrical power for scene lighting, fans, and small tools while the engine runs. The typical rating chosen for most installations is up to 12,000 watts (12 kW). This level offers ample power to run multiple lights and essential equipment without making the unit too heavy, fuel-hungry, or bulky for a standard vehicle setup. A 5,000-watt unit is usually underpowered for common lighting and tool needs; a 20,000-watt unit exists but is larger and less common on standard apparatus; and 50,000 watts would be excessive for most vehicle-mounted systems. So, up to 12,000 watts is the most representative typical capacity.
