In North America, AC (alternating current) power is produced at a frequency of 60 hertz. This frequency indicates that the current alternates direction 60 times per second, which is a standard used in the electrical power distribution system for residential and commercial use.

The choice of 60 hertz has historical roots and has been widely adopted throughout the country. It allows for the efficient operation of electrical appliances and systems that are designed to work on this frequency. Other regions, such as Europe, typically use 50 hertz, which is why understanding the frequency specific to North America is crucial for any gas technician or electrician working in the field.
