What is nominal voltage?

Nominal voltage refers to the voltage level at which an electrical system is designed to operate. It is the standard voltage that a device is rated to handle for proper operation.

In most countries, the nominal voltage for household electrical systems is typically around 120V or 230V, depending on the region. Higher voltages, such as 480V or 600V, are commonly used in industrial settings.

It is important to note that nominal voltage is not always the same as the actual voltage that is delivered to a device. Variations in voltage levels can occur due to factors such as distance from the power source, electrical load on the system, and other external factors.

Maintaining the proper nominal voltage is important for the safe and efficient operation of electrical systems and devices. Improper voltage levels can lead to equipment damage, power outages, or even safety hazards.
