For messenger-supported wiring, how should conductors enter the box?

In messenger-supported wiring, conductors should ideally enter the box through one large hole. This design is beneficial as it helps accommodate multiple conductors more efficiently and reduces the risk of damage to the conductors during installation or maintenance. Using a large entry point allows for a better organization of wires, which can also simplify the installation process by enabling easier handling of the conductors without the need for managing multiple individual entry points. This method can enhance the overall safety and integrity of the wiring installation.

In contrast, entering through conduit might limit flexibility, as conduits require careful routing and may not be as adaptable to changing circumstances. Individual holes could create points of stress at the entry, potentially leading to insulation wear over time. Secured points can increase installation complexity and may not be as effective at providing a unified entry, which is crucial for messenger-supported configurations.
