What is Horsepower?
Horsepower is a unit of measurement used to quantify the power output of motors and engines, including those used in electrical systems. In electrical work, horsepower helps determine the size and capacity of electric motors, such as those found in HVAC systems, well pumps, or industrial machinery. One horsepower is equivalent to 746 watts.
In residential and commercial electrical applications, understanding horsepower is crucial for selecting the right motor or generator to match a system’s energy demands. For instance, electricians often refer to horsepower ratings when installing or servicing equipment to ensure proper performance, efficiency, and safety. Overloading a motor by underestimating its horsepower requirement can lead to overheating, increased energy use, and equipment failure.
