The recommended mounting heights for electrical equipment, as outlined in NECA-1, Section 11, Table 3, are measured from the finished floor to the centerline of the equipment. This standard is important for providing consistency and ensuring that installations meet accessibility and safety requirements.

Measuring to the centerline rather than to the highest or lowest points of equipment allows for a standard reference that can be consistently applied across different types of installations. This method ensures that all users can interact with the equipment in a similar manner, promoting a uniform height that is neither too high nor too low, thereby facilitating easier access and operation.

Using the centerline measurement also helps in planning the layout of electrical panels and devices in relation to other fixtures or components in a space, which is critical for maintaining proper workflow and efficiency in both residential and commercial applications. This approach aligns with safety and compliance considerations that are fundamental to electrical installations.
