[Milsurplus] Mil generator

[WA5CAB at cs.com]

The theoretical (exact) conversion factor is 745.7 watts per horsepower.  So 
10 KW would be 13.41 HP.  To be on the safe side, 15 HP.  However, 
manufacturers tend to lie a bit, so 20 would be safer.  And be sure that you know the 
engine's HP rating at the generator's operating RPM.  Gasoline and diesel engines 
have quite steep HP versus RPM curves.  For NG operation, derate the engine 
about 20%.  Propane a bit less.  And if the generator is a 3600 RPM plant, be 
sure that the engine is rated to run continuously at that RPM.  Automotive 
grade engines don't last long running that fast.

Also, you said 220 VAC for the generator.  Should be 120/240V 60Hz single 
phase for residential standby generator service in the USA.
