In long conduit runs, pole boxes are installed at intermediate points to?

In long conduit runs, pole boxes are primarily installed to facilitate the pulling of wires. During the installation process, these boxes, also known as junction boxes or pull boxes, provide access points along the conduit system. When running long stretches of wiring, navigating around bends or managing resistance can be challenging. Intermediate boxes offer a convenient location to pull wires through, reducing strain on the wires and making it easier to maneuver them through the conduits. This allows for a smoother installation process and helps prevent damage to the wires, ensuring that they can be properly fed and positioned within the conduit system.

In contrast, protecting the wires, signaling electrical loads, or increasing circuit capacity are not the primary functions of pole boxes. While they may contribute to wire safety indirectly by serving as access points, their main role is to ease the installation and handling of wires in longer conduit runs.
