Which illustration satisfies the Code requirements of 240.22(1)?

To determine which illustration satisfies the Code requirements of 240.22(1), it is essential to understand the provisions of this section of the National Electrical Code (NEC). Section 240.22(1) addresses the installation and arrangement of overcurrent protection devices concerning their accessibility and clearance.

The illustration identified as correct typically demonstrates proper spacing and organization of overcurrent devices, ensuring adequate access and safety. This means that the illustration adheres to the NEC's stipulations about maintaining a clear access area and avoiding installation in a way that would create hazards or difficulties in operation or maintenance.

In contrast, other illustrations may fail to depict proper compliance due to factors such as insufficient working space, improper mounting heights, or arrangements that could complicate maintenance or increase the risk of accidental contact. By meeting these specific requirements, the selected illustration not only aligns with the code but also promotes safety and functionality in electrical installation practices.

Evaluating the illustrations based on these criteria aids significantly in understanding NEC standards and their practical applications.
