What is the typical application for a pull box in a conduit system?

In a conduit system, a pull box serves important functions, and one of its primary applications is to provide access for maintenance. This means that technicians or electricians can easily reach the cables within the conduit system for inspections, repairs, or modifications without needing to open up the entire conduit system.

While options like acting as a junction for connections, allowing for changes in direction, and reducing cable tension are also valid functions that pull boxes can serve, the key focus on providing maintenance access highlights the critical need for ease of service in electrical installations. This is particularly important in ensuring that systems remain operational and safe. Having accessible points for maintenance helps in troubleshooting and ensures that any necessary adjustments or repairs can be made promptly, simplifying overall system management.
