What is the maximum horsepower rating for motors controlled by UL-listed alternating current, general-use snap switches?

For UL-listed alternating current, general-use snap switches, the maximum horsepower rating is specifically defined to be 2 horsepower. This rating ensures that the switch can safely handle the electrical load and the inrush current characteristics associated with motors.

Using a general-use snap switch rated for 2 horsepower allows electricians and users to effectively control small motors without exceeding the safety limits established by UL standards. This specification is critical for preventing overheating, maintaining reliable operation, and ensuring compliance with electrical codes.

Higher horsepower ratings, such as 3 or 5, exceed the capacity of these switches and could pose safety risks, such as fire hazards or equipment damage. By understanding the correct horsepower rating, professionals can select the appropriate switch for specific applications, thereby maintaining the safety and integrity of electrical systems.
