The concept of grounding is well known, but details in the code are allowing installers to make preventable mistakes. After a review of those grounding mistakes, we’ll overview what the National Fire Protection Association (NFPA) emphasized to the public this summer. 

Then, from an inspector’s point-of-view, what was New Orleans like after Hurricane Katrina?

What’s What: Grounding, Bonding and Earthing

Posted by The nVent ERICO Team on Jun 19, 2018 1:33:46 PM

Grounding and bonding are an integral part of any modern electrical protection system design. An effective, low-imped­ance ground system is the foundation of an electrical system, regardless of structure type. It is crucial to help provide personnel safety, as well as reliable protection for vital equipment, as well as to minimize inter­ruptions of service and costly downtime. Knowing the difference between grounding, bonding and earthing is imperative to properly design and install an electrical grounding system.

But first, let’s define the terms.

  • Ground: A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth.
  • Earth: The conductive mass of the earth, whose electric potential at any point is conventionally taken as equal to zero. In some countries the term "ground" is used instead of "earth."
  • Bond: The permanent joining of metallic parts to form an electrically conductive path that will ensure electrical continuity and the capacity to conduct any current likely to be imposed.

Why a Proper Grounding System Is the Key to Effective Lightning Protection

Posted by Brian Liederbach on Apr 10, 2018 8:02:00 AM

Lightning currents inherently want to ground—whether the proper systems are in place or not. A lightning strike, which is intercepted by an air terminal, must have its current transferred to the earth safely and seamlessly. 

The grounding system is the integral part of a modern electrical lightning protection system that must be dependable for this process. 

Without an effective grounding system in place, dangerous ground faults, side flashes and electronic noise can occur, causing damage to structures, fires or personal injury.

3 Reasons Engineers Should Choose Copper-Bonded Ground Rods

Posted by Rohit Narayan on Jan 16, 2018 8:04:00 AM

Picture yourself driving your car on the highway when all the of the sudden you see brake lights and are forced to slow down because of construction. As you come to a stop, you see workers repaving a damaged road. Now, cars begin to line up in front of you and behind you. Where do you go? Nowhere—you’re stuck.

A ground rod, also known as an electrode, is similar to this highway scenario. It acts as the only electrical path to dissipate static discharge voltage (such as lightning) into the earth. When that path starts to break down, the static discharge has nowhere to go and puts the whole system at risk.

Many times, engineers are given the choice between three types of ground rods: copper-bonded steel, copper clad ground rods or galvanized steel for grounding systems. However, one material reigns supreme when it comes to strength, service life and overall investment. Hint: it’s copper bonded steel. 

Continue reading below to learn why copper is the better choice for grounding systems versus it’s steel alternative.

3 Considerations to Maximize Grounding System Life

Posted by Andrew Ritosa on Dec 12, 2017 8:02:00 AM

While there’s no known solution to completely protect your facility from naturally occurring environmental threats, certain steps can be taken to minimize risk. These precautionary steps to total facility protection include the following concepts:

  • Direct strike protection
  • Grounding and bonding systems
  • Transient surge and over-voltage protection

To maximize both the effectiveness and service life of a grounding system, careful considerations must be followed. Read below to learn three considerations to keep in mind when installing your next grounding system.

5 of the Most Common Electrical Grounding Mistakes You Can Make

Posted by Greg Martinjak on Sep 5, 2017 8:04:00 AM

Your facility, technology and other key assets are at risk to lightning strikes. While an effective air termination device and above ground lightning protection system is critical to effective protection, proper grounding can keep people and products out of harm’s way. 

Preventable mistakes in the electrical grounding system can leave it vulnerable to ground faults, side flashes and electronic noise, any of which could result in fire, damage to structures and personal injury. 

Below we outline 5 common mistakes made when designing and installing a grounding system.

How Grounding System Helped Gold Mine Overcome Rocky Soil Conditions

Posted by Martin Havelka on Jun 27, 2017 8:08:00 AM

The Peak Gold Mine, located in New South Wales, Australia, provided gold deposits and copper concentrate throughout the Asian Market from 1896 to 1920.

While the Peak Gold Mine concluded production long before the change of the millennium, production resurfaced at the mine in the mid 2000s, thanks to the discovery of additional gold.

Despite challenging ground conditions, miners at the Peak Gold Mine have uncovered 99,072 ounces of gold, along with 9,070 tons of copper, and have a predicted working life through 2020. 

So how was this massive amount of materials unearthed from a century-old mine? Continue reading to learn how ERICO Ground Enhancement Material (GEM) improved the grounding system and power quality at Peak Gold Mine.
