What is the difference between a pull box and a junction box in limited-energy installations?

• A. Pull box provides space to pull cables; a junction box houses splices and terminations.
• B. Pull box houses splices and terminations.
• C. They are the same.
• D. Junction box provides space to pull cables.

Answer: (A)

In limited-energy installations, the purpose of each enclosure is distinct: a pull box is placed in a cable run to provide extra space and access for pulling conductors through the run, whereas a junction box is used to enclose splices and terminations once the connections are made. The pull box’s job is about making installation feasible during pulling and future re-strings, not about joining wires. The junction box’s job is to protect and house the actual connections where conductors are spliced, tapped, or terminated. That’s why the statement describing a pull box as providing space to pull cables and a junction box as housing splices and terminations is the correct way to differentiate them. The other options mix up these roles or claim they are the same, which doesn’t reflect how these enclosures are used in practice.
