What is the minimum calculated dimension for width in another pull box as per the reference figure?

The minimum calculated dimension for width in another pull box is established based on the need to ensure sufficient space for electrical connections, maintenance, and accessibility. A width of 34 inches is recognized as adequate to accommodate the necessary components while allowing for safe and efficient work within the pull box. This dimension has been specified because it strikes a balance between user accessibility and the operational requirements for wiring and equipment.

Using a width that is too narrow could limit the ability of technicians to perform repairs or adjustments effectively, thus impacting the safety and efficiency of electrical work. Moreover, the National Electrical Code (NEC) and industry standards guide these dimensions to ensure compliance and safety in electrical installations. Thus, a pull box width of 34 inches adheres to the necessary regulations and best practices in the field, making it the correct choice for the minimum dimension in this scenario.
