What is the rated voltage of dual-voltage-rated pump motors?

Dual-voltage-rated pump motors are designed to operate at two different voltage levels and are commonly rated at 115/230 volts. This means that they can be connected to either a 115-volt or a 230-volt circuit. The ability to switch between these voltage levels allows for greater flexibility in installation and can be beneficial in applications where different voltage supplies may be available.

The convention of using 115/230 volts aligns with typical residential circuit voltages in the United States, where 120 volts is commonly encountered in household outlets, and 230 volts is utilized for larger equipment and appliances. This design helps ensure that the motors can function effectively regardless of the specific voltage supplied.

While it’s possible to encounter various voltage ratings in different regions or contexts, the 115/230 volt rating is the standard for dual-voltage pump motors used in residential applications.
