A 10 hp motor with service factor 1.15 can handle how much horsepower?

Explanation:
Service factor shows how much extra load a motor can safely deliver beyond its nameplate horsepower, without overheating or stressing the components. Multiply the rated horsepower by the service factor to get the maximum load the motor can handle under those conditions. So for a 10 hp motor with a service factor of 1.15, the maximum continuous load is 10 × 1.15 = 11.5 hp. This isn’t a recommendation to run at that level all the time, but the overload allowance the motor can manage within its design limits. If a value were higher, it would correspond to a larger service factor; if lower, a smaller one.
