The correct answer indicates that the ampere rating for an AC general use snap switch controlling inductive loads is set at 50% of the switch's normal ampere rating. This reduction is primarily due to the unique characteristics of inductive loads, which typically involve motors and transformers that can draw significantly higher inrush currents during startup.

These inrush currents exceed the normal operating current and can cause the switch to overheat or fail if operated at full capacity. Therefore, to ensure safety and reliability, the National Electrical Code (NEC) and industry standards recommend that the ampere ratings for such switches be limited to 50% when dealing with inductive loads. This regulation ensures that the switch can adequately handle the inrush current and provide a longer lifespan while maintaining safe operating conditions. Understanding this principle is critical for passing the Master Electrician Exam, where knowledge of proper ratings and safe practices is essential for effective electrical work.
