What is the minimum size of conduit that is commonly used for laying out Auxiliary Devices?

The minimum size of conduit commonly used for laying out Auxiliary Devices is often ¾" diameter. This size is typically preferred because it provides adequate space for wiring and allows for easy pulling of the conductors, which helps prevent damage to the wires.

Using ½" diameter conduit can restrict airflow and create challenges during installation, especially if multiple wires need to be accommodated. Additionally, while PVC molding is indeed used in electrical installations, the specific term used typically refers to a finishing method rather than conduit size itself.

Therefore, ¾" conduit is the standard that balances functionality and compliance with electrical codes, making it well-suited for auxiliary devices.
