What is a “pull box” used for?

A pull box serves a crucial role in the installation and maintenance of electrical wiring systems, specifically designed for the purpose of aiding in the pulling of wires through conduits or raceways. These boxes provide enough space for electricians to easily maneuver wires during installation or repair, helping to reduce stress on the wires and minimizing the risk of damage.

Pull boxes are typically installed at various points along long runs of conduit where it may be difficult to pull wires directly through due to length or bends in the raceway. By allowing a point where the wires can be accessed more easily, pull boxes help facilitate the installation process, making it more efficient and safer.

In contrast, a pull box is not intended for connecting circuit breakers, which are housed in a panelboard or distribution board to provide protection and control for electrical circuits. Additionally, while pull boxes assist in managing wire installations, they do not serve as a power source for appliances, nor are they designed to support electrical panels, which require specific mounting hardware and structural considerations.
