Question

An AC-DC general use snap switch is utilized to control an inductive load. What's the largest percent of its ampere rating that it may be loaded?

Answer 1

The largest percent of an AC-DC general use snap switch's ampere rating that it may be loaded to control an inductive load is typically 80%, to ensure safety and prevent component failure.

Step-by-step explanation:

When an AC-DC general use snap switch is used to control an inductive load, the largest percent of its ampere rating that it may be loaded is generally 80%. This safety regulation is in place to prevent overheating and potential failure of electrical components due to continuous use. With inductive loads, such as motors and transformers, there is an additional consideration for the inrush current, which can exceed the steady-state operational current. Therefore, the rating of the switch must accommodate the inrush current without tripping, but the continuous current should not exceed 80% of the switch's rated capacity.
