ScTP cabling grounding and bonding considerations :: | 5/55

| Grounding and bonding systems are an integral part of the screened twisted-pair (ScTP) telecommunications cabling system. In addition to helping protect personnel and equipment from hazardous voltages, a proper grounding and bonding system may reduce EMI to and from the telecommunications cabling system. Improper grounding and bonding can produce induced voltages and those voltages can disrupt other telecommunications circuits.

Requirements

Grounding and bonding shall support applicable authorities or codes.

- In addition, telecommunications grounding/bonding shall conform to ANSI/TIA/EIA-607 requirements.
- The shield of ScTP cables shall be bonded to the telecommunication grounding busbar (TGB) in the telecommunications room.
- At the work area end of the horizontal cabling, the voltage measured between the shield and the ground wire of the electrical outlet used to supply power to the workstation shall not exceed 1.0 V RMS. The cause of any higher voltage should be removed before using the cabling.

> NOTE: Grounding at the work area is usually accomplished through the equipment power connection. Shield connections at the work area are accomplished through an ScTP patch cord.
