In a typical Data
Center, you will often have many different ground bars in use through out the
facility. For example, in the electrical
room, you will not only have the green
wire low-impedance fault current path required, but you may also have a safety
ground system with multiple ground bars used to bond the various metallic
objects found within the room (electrical panels, conduit, air handling
equipment, fire suppression, doors, gates, fences, etc)
In the computer room, you will have a requirement for
a copper ground bar to be installed inside each computer server rack. TXM offers both 19” and 23” bus bars which can
be used on 2 post and 4 post racks. For

There are
also additional ground bar (s) mounted on the wall of the server room that will
be used to bond all the server rack ground bars together, along with the
conduit bonds, air handling equipment bonds, door bonds, UPS power supply,
etc. This server room ground bar (s) must in turn be bonded back to the
main ground bar in your Telco room, and back to the first service disconnect in
the main electrical room. There are typically requirements for dedicated 5-ohm or
less grounding electrodes that must be bonded to the server room ground bar (s). TXM offers various sizes of wall mount bus
bars for standard, TGB and TMGB series bus bars. TGB bus bars (Telecommunications
Grounding Bar Kit) provide a common grounding point within the
telecommunications room. The TGB is the attachment point for all
telecommunications systems and equipment in a specific telecommunications
space. Therefore, each telecommunications space through out the building
should have a TGB. These are typically installed on a wall inside the
data telecom room, allowing each telecommunications room to provide a common
point of connection for systems and equipment bonding to ground. TMGB bus bars(Telecommunications Main
Grounding Bar) are used as the foundation of the telecommunications grounding
system and serve as an interface between the building's service equipment
(power) ground and the telecommunications infrastructure. The TMGB also
serves as a central connection point for the telecommunications bonding
backbone (TBB) and equipment. There is usually only one TMGB per
building.

You may have additional ground bars used for the
bonding of the lightning protection system, back-up generator systems,
electrical substations, equipment chassis, and many more. All of these
ground bars and grounding systems must be bonded to each other in manner that
does not cause additional problems with ground loops, resulting in harmonics
and electrical interference.
In addition, TXM
also offers isolation rack adapter kits, which include the rack adapters along with
isolation pads, bushing nylon washers and screws. These can be used for additional ground
isolation protection when mounting telecom equipment onto the racks. For more information, follow this link: https://www.txmstore.com/telecom-accessories/hardware-shelves-racking/iso-rackmount-adapters/
