The typical operating frequency for AC power in the United States is indeed 60 Hertz (Hz). This frequency is standardized across the electrical grid and ensures compatibility and efficiency in the operation of electrical appliances and systems.

Using this frequency allows for effective generation and transmission of electrical energy. Equipment designed for 60 Hz operation is commonplace in American households and businesses, meaning that appliances and motors are optimized to run at this frequency for optimal performance and longevity.

In contrast, other frequencies, such as 50 Hz, are used in different parts of the world, notably in Europe and many other countries. Frequencies like 40 Hz or 70 Hz are less common and not used as standard operating frequencies in any major electric power systems. Understanding this frequency is crucial for anyone involved in electrical engineering or the installation of electrical systems, as it affects system design, efficiency, and device compatibility.
