What is the minimum depth required for a pull box with a 2½” rigid metal conduit?

The minimum depth required for a pull box with a 2½” rigid metal conduit is 4 inches. This requirement ensures that there is sufficient space for wiring and connections within the pull box without the risk of overcrowding or potential damage to the conductors.

Pull boxes are designed to provide accessibility for pulling and splicing conductors safely and efficiently. The specified minimum depth accommodates various wire sizes and types, as well as ample room to maneuver when making electrical connections. Adhering to these depth standards helps maintain safety and compliance with electrical codes, reducing the likelihood of overheating or failures.
