What is a common field practice for grounding shielded cabling?

Shielded cabling works best when the shield has a solid ground reference, so EMI has a low-impedance path to return there. Connecting the shield to the equipment grounding conductor gives this path, pulling interference away from the signal wires and toward earth/ground rather than letting it couple into the data. If the shield is left floating, it can’t shunt noise; if it’s tied to a data line or to neutral, it won’t provide a reliable ground reference and can create ground-loop issues or safety concerns. So, the common field practice to reduce EMI is to ground the shield to the equipment grounding conductor.
