When terminating cables containing a shielding drain wire, what must be done with the drain wire?

When terminating cables that have a shielding drain wire, it is essential to ground the drain wire. The purpose of the shielding drain wire is to provide a path for any induced or stray electrical noise to be safely directed to ground. By properly grounding the drain wire, you help to maintain the integrity of the signal being transmitted through the cable, reducing electromagnetic interference and ensuring the overall performance of the electrical system.

Grounding the drain wire also helps to prevent shock hazards and improve safety in the installation, as it prevents the accumulation of electrical charges on the shield. In contrast, isolating, capping, or reusing the drain wire without grounding can lead to increased electromagnetic interference, compromised signal integrity, and potential safety risks within electrical wiring systems. Proper grounding practices must follow industry standards and guidelines to ensure safe and reliable operation.
