looking at buying this generator from a guy to power a foam reactor. The motor is kubota dm850 which i am extremely familiar with and can rebuild with my eyes closed. The power distribution will be redone to my specifications. I am trying to figure out exactly what the generator head itself is. I am attaching pictures of the plate and all of the pictures i have. The guy says it came off a trailer that powered big work site lights. he thinks it is a 6 kw but it has 2 220 30 amp plugs so my math says it is a minimum of a 12 kw. Any help would be appreciated.
