How must switches and circuit breakers used as switches be installed for operation?

In a secure area
From a readily accessible place
Near the main panel
In a protected enclosure

The correct answer is: From a readily accessible place

For switches and circuit breakers that are used as switches, it is essential that they are installed from a readily accessible place for safe and efficient operation. This means that individuals should be able to reach the switches or breakers without any obstruction or the need for special tools, ensuring that they can quickly turn off power in case of an emergency or maintenance. Accessibility is crucial not only for normal operations but also for safety concerns—regular access allows for prompt action during troubleshooting, emergencies, or electrical failures. While security, proximity to the main panel, and protection from environmental factors are important considerations for overall functionality and longevity, the primary requirement centers on ensuring the switches and circuit breakers can be easily and quickly accessed. This principle is often emphasized in electrical codes and safety standards to promote safe practice in electrical installations.
