What is the minimum calculated dimension for "height" in inches, as noted for a specific pull box?

The minimum calculated dimension for "height" in inches for a pull box is set to ensure compliance with safety standards and facilitate ease of access and operation. Specifically, a height of 44 inches is aligned with regulations that address accessibility for individuals with disabilities and the general requirements for equipment that must be reachable by personnel.

This dimension helps guarantee that the pull box is accessible without the need for bending or stretching excessively, thereby reducing the likelihood of strain or injury while ensuring that the box can be easily operated or maintained. Adhering to this height also ensures that the equipment is compliant with the National Electrical Code (NEC) and other relevant standards, which are crucial for safety and uniformity within electrical installations.

The other options present heights that fall below the acceptable standards for accessibility and operability of electrical equipment, failing to meet the necessary guidelines for the installation and maintenance of pull boxes in electrical systems.
