The Three ‘E’s’ of Telecommunications Bonding System

Did you know that there are three distinct components for the Telecommunications Systems Bonding Infrastructure? They are the Grounding Electrode System, the Equipment Grounding System, and the Telecommunications Bonding System. Some people have a hard enough time understanding just ONE of these systems; let alone three! But no need to worry…there’s a simple but accurate way to understand them. We call it, the ‘3 E’s’ and here’s how to break them down.

Grounding Electrode System – Often called ‘earthing’, the purpose of this system is to Establish the voltage reference for the electrical service entrance and other power sources within the building.

The Equipment Grounding System – Commonly called the ‘safety ground’, the purpose of these connections is to Extend the zero-volt reference to equipment frames.

Telecommunications Bonding System – The sole purpose of this system is to equalize potentials during lightning, electrical fault, static discharge, or electromagnetic interference (EMI) conditions.

Below are the three systems visualized.

Why are there three systems, you ask? Well, consider this:

  • There are three separate reasons why we have each.
  • There are three different methods of testing each.
  • There are three different methods of improvement.

As a final note, please remember that telecommunications installers, designers, and technicians have no jurisdiction outside of the telecommunications bonding infrastructure. As such, it is very important to understand these other two systems as much as possible and inspect ALL of them periodically.
