Which of the following best describes "readily accessible"?

The term "readily accessible" is defined in the National Electrical Code (NEC) as referring to equipment or installations that can be reached without significant obstacles and without the need for tools, ladders, or special permissions. The correct choice highlights that "readily accessible" means that the item can be accessed immediately and directly, making it possible for individuals to operate or maintain it without delay.

This definition aligns with safety requirements and operational efficiency, ensuring that vital equipment can be quickly reached in case of emergency or regular maintenance. Equipment that is readily accessible supports both safe practices in electrical installations and prompt response in critical situations.

In contrast, options that mention requiring tools or ladders, being in hard-to-reach areas, or being behind locked doors diverge from the intended meaning of the term because they imply difficulties or restrictions in access that are not consistent with the concept of being readily accessible.
