A 3-pole, general-use snap switch can control what?

A 3-pole, general-use snap switch is designed to control multiple circuits simultaneously. This type of switch is capable of interrupting the flow of electricity for three separate circuits, making it particularly useful in applications where several circuits need to be controlled from a single location.

This functionality allows for efficient management of electrical systems, especially in more complex setups. The ability to control multiple circuits means that the switch can handle various loads, providing both flexibility and convenience. In contrast, options specifying a single circuit or only listed circuits do not accurately reflect the capabilities of a 3-pole switch, which is specifically engineered to manage more than one circuit at a time. Thus, the option indicating that a 3-pole, general-use snap switch can control multiple circuits is the correct choice.
