A multipole, general-use snap switch shall not be fed from more than a ? circuit unless it is listed and marked as a two-circuit or three-circuit switch.

• A. Single
• B. Two
• C. Three
• D. Four

Answer: (A)

General-use multipole snap switches are designed to interrupt a single circuit unless the switch is specifically listed and marked as capable of handling two or three circuits. This ensures the internal insulation, contacts, and overall ratings match what the device is designed to safely interrupt. Feeding it from more than one circuit when it isn’t listed for multi-circuit use creates potential safety hazards, such as unwanted cross-connection between circuits or inadequate isolation. Only if the switch is explicitly listed for two or three circuits is it permitted to be fed from more than one circuit. The other options would be allowed only if the switch carries the corresponding listing.
