Leviton 0-10V dimmers feature wire leads that are rated for line voltage applications. This eliminates the need to have separation between the line voltage and low voltage within the wallbox.
For wiring techniques between the dimmer wallbox and ballast/driver, please refer to the relevant NEC® or to your Authority Having Jurisdiction (AHJ) guidelines. Generally, low voltage CANNOT be run in the same conduit as line voltage if class 1 or class 2 wiring is used. If line voltage rated wires are used throughout, the low voltage wires can be run through the same conduit (given that conduit/conductor fill requirements are met).
