Just bought a new Predator Generator from Harbor Freight. The specs are impressive and it starts right up and runs very quietly. I am replacing a smaller generator with the hope that I will be able to occasionally run my AC unit. One thing that troubles me is that they say not to run the gen with more than a 75% load until after a 30 hour break in period. They don't specify exactly what that means. The steady state capability is 3000 watts and 75% of that is 2250 Watts, which may be enough to run the AC but I'm not sure. The starting capability is 3500W and at 75% that would be 2625W, which might be exceeded during the AC start up. I hate to just run the gen for 30 hours without getting any use out of it. Anyone have any idea what the risk factors are in just going ahead and using it after a much shorter break in period? I currently have 4 hours on the gen.
