Alternating-current general-use snap switches can control resistive loads up to what limit?

On a circuit not exceeding 20A
Up to the ampere rating at 120V
1.5 times the ampere rating of the switch
Only DC loads

The correct answer is: Up to the ampere rating at 120V

Alternating-current general-use snap switches are specifically designed to control electrical loads, and understanding their specifications is critical for safe installations. The correct choice highlights that these switches can manage loads up to the ampere rating at 120V. When a switch is rated for a specific current at a common voltage level like 120V, it means that it can safely handle electrical loads that draw current up to that rating under typical use conditions. This limit ensures that the switch does not overheat or fail due to excessive current, which is essential for both safety and proper function. Illicit load levels can lead to failures or hazards, so adhering to the specified limits is vital. While the other options suggest various parameters for load management, only this statement accurately captures the fundamental specification of general-use snap switches in a way that relates directly to their operational safety and design ratings. This understanding helps electricians ensure that their installations comply with safety codes while maintaining functionality within the electrical system.
