What size conductor is used to bond equipment racks?

A minimum 1-inch copper braid (strap), or No. 8 AWG conductor, has to be used for equipment bonding.

What is grounding equalizer?

Grounding Equalizer (GE): Whenever two or more TBBs exist in a multistory building, they must be bonded together with a GE at the top floor and at every third floor in between. The GE is also sized the same as the TBB.

What is R56 grounding?

R56 is a widely accepted industry standard; that details the requirements and guidelines for the installation of communications infrastructure and facilities. This standard is extensively used by customers; consultants and even competitors for their installations.

Why telecommunication grounding and bonding is necessary?

Electrical systems and communication cabling systems that are required to be grounded must be connected to the earth. The grounding mechanism must provide a reliable means to safely conduct the voltages imposed by lightning, line surges, or unintentional contact with high voltage lines or equipment to ground.

How is grounding system designed in Motorola R56?

As part of the design of a single-point grounding system of adequate wire size, ground rod length, and ground plate size, as prescribed in Motorola R56, Alltec engineers take into account all systems that need to be bonded to the grounding system.

What is the Motorola R56 surge protection standard?

Motorola R56 Standard Surge Protection R56 standards and guidelines drive stringent surge protection requirements necessary for high reliability communications networks. As part of Infinite Electronics, PolyPhaser and Transtector Systems provide a full line of surge protection products for data and signal line, RF, AC and DC applications.

What do you need to know about R56 standards?

R56 standards and guidelines drive stringent surge protection requirements necessary for high reliability communications networks. As part of Infinite Electronics, PolyPhaser and Transtector Systems provide a full line of surge protection products for data and signal line, RF, AC and DC applications.

What are the ground rods for Alltec R56?

R56 requires all ground rods to be UL listed. Ground rods are also required to be buried to the depth of 30” or lower, along with the grounding wire (typically a #2 solid copper, tinned wire). If the ground rod cannot be driven to 30“, a 45-degree angle or horizontal installation at a depth of the ground wire is also acceptable.
