A lot of people are saying motors aren't made to run 100% all the time. While I agree with that but I worked on a rock crusher for the longest time and we were portable so everywhere we went we had all of our belts, jaws, cones, qc lab, 10k gallons of diesel and a trailer that carried two cat c27 generators for when we didn't have line power. They were twin turbo capable of up to 600 volts at 60 hz. Big difference to what your needing. I'm only saying that we would run those 24 hours a day non stop. Sometimes hooking everything to one if the other was down. By then end of shift the turbos were glowing hot red. Point is motors can run like that.
