What is the main purpose of a pull box in electrical installations?

The main purpose of a pull box in electrical installations is to facilitate maintenance. Pull boxes are strategically placed along conduit runs or cable routes, allowing for easier access to conductors and wiring. This accessibility is crucial for various maintenance tasks, such as making connections, splicing wires, or troubleshooting electrical issues without needing to dismantle large sections of conduit or cable pathways.

The design of pull boxes helps ensure that technicians can perform work safely and efficiently, reducing downtime and minimizing potential hazards that could arise from accessing tight or complex wiring arrangements. This ease of maintenance is a primary consideration in planning electrical installations, as it promotes safety and practicality in ongoing electrical system management.
