AC or DC general use snap switches can control inductive loads not exceeding what percentage of the ampere rating of the switch?

When it comes to controlling inductive loads with AC or DC general-use snap switches, it's important to adhere to the manufacturer’s specifications and the National Electrical Code (NEC) guidelines. Inductive loads, such as motors and transformers, can create a higher initial inrush current when they are energized, which can lead to premature failure of the switch if not managed correctly.

For general-use snap switches, the accepted standard is to limit the controlled inductive load to a maximum of 50% of the switch's ampere rating. This guideline helps ensure that the switch can handle the inrush current without being damaged, while still functioning effectively for its designed purpose. By adhering to this percentage, electricians can reduce the risk of overheating and ensure the longevity of both the switch and the connected load.

Understanding this regulation is crucial for proper electrical installations, as it aids in preventing potential hazards and promotes safety within electrical systems. Thus, knowing that snap switches can safely control inductive loads at up to 50% of their rated ampacity is key for compliance and operational efficiency.
