When installing network cabling, it is important to maintain a minimum of **6 inches (200 mm)** distance between power and data cables.
If the cables must cross, they should cross perpendicularly, not in parallel¹.
The minimum separation distance between unscreened power and unscreened UTP cable is **200 mm**.
This is reduced to **50 mm** for screened data cable and to just **30 mm** if the power cable is screened³. Connectix recommends that power and data cables are installed with a **200 mm** separation wherever possible.
A **600 mm** separation should be maintained between data and three-phase power cables.
