Hey Soundguy, I am going based on the specs on the Northern Tool site.
NorthStar PTO Generator 13,000 Watt, 24 HP Required | PTO Generators | Northern Tool + Equipment
Maybe their specs might have an error, but they list four 20 amp 120v, one 30 amp 120v and one 50 amp 120v, no 240 receptacle. Is this how your unit is? Does this look like the exact same as yours, or is it a slightly newer model with slight variations?
If this is the case, to pull the full 12,000 watts, you would have to connect a combination of 3 or 4 receptacles to get the full wattage, while also knowing how they are connected internally to the generator, so that a balance can be maintained and pull 6000 watts from each pole. If there is a 240v 50 amp receptacle, then it would be all good. 50 amps x 240 volts gives 12000 watts and supplying a panel would be easier.
jd2305cd, I agree about your lil 2305. I think commercial engines like the Honda are good, but I think the engine on your 2305 hooked up to a PTO gen would blow these gasoline gens away , just my thoughts
