Our big sets were all 'hospital' rated, which means they will take rated load within seven seconds of a start command. We used them because the transmitters would withstand a seven second power loss and run immediately instead of going through the entire start sequence. Which in a Top Ten market equates to money. A Cummins 'Big Cam' engine will not take load when the block is twenty degrees Fahrenheit, things will break. So part of the package is a block heater which keeps the set ready to run. They ran with load thirty minutes a week. This routine did in fact fail one engine to a leak in a cylinder liner, but it took 25 years of service to do it. The set was still running, but poorly and getting hot. We put an Onan rebuilt short block in it and kept going. That was ten years ago, the set is still working fine. Which brings up a couple of truisms. Like the coaches, they respond better to use than to sitting; and if you don't run them regularly there's no guarantee they'll run when you need them.
