A snap switch shall not be grouped with other similar devices unless the voltage between adjacent devices does not exceed what?

The appropriate voltage limit for grouping snap switches with other similar devices is 300 volts. This regulation is in place to ensure safety and prevent potential electrical hazards that can arise when devices are operating in close proximity to each other.

When snap switches are used together, they must be installed in a manner that considers the voltage present between them. If the voltage exceeds 300 volts, there is an increased risk of arcing, short circuits, or electrical failure, which could lead to equipment damage or personal injury. Keeping the voltage at or below this threshold helps maintain a safe operating environment and promotes compliance with electrical codes and standards that govern the installation of electrical devices. Therefore, keeping the voltage limit at 300 volts ensures that safety is prioritized while allowing for effective use of snap switches in various applications.
