    ATLANTA, GA, April 29, 2014 /24-7PressRelease/ -- Earth grounding is one of the most important safety considerations to remember when creating an electrical system. The residential electrical contractors at Pat Murphy Electric, Inc., wish to explain some basic information about earth grounding.

Earth grounding is used to give power surges caused by lightning strikes, static charges and other types of electrical interference an easy and controlled way to dissipate. Atlanta electrical contractors most commonly create an earth grounding system by attaching a ground wire to a metal rod, pipe or plate, which they then bury in the ground.

Creating a safe electrical system through earth grounding requires a low level of resistance within the grounding wire. The commercial electricians at Pat Murphy Electric, Inc., note that the best possible ground wire resistance would be zero ohms in theory, but this is often not possible or practical in a real system. Acceptable resistance in any application is 25 ohms, but many industries recommend grounds with a resistance of five ohms or less.

Grounding systems come in two different system styles: simple and complex.

"Simple earth grounding systems are far and away the most commonly used type for homes and single buildings," says Guy Roberts, CEO of Pat Murphy Electric, Inc. "Simple systems involve the use of just a single grounding electrode."

More complex systems involve multiple grounding rods, which are typically placed in a mesh or grid pattern to provide additional grounding. Power plants and other high-electricity applications are typically where complex systems are seen.

To properly install an earth grounding system, you will need to hire a licensed and trained electrician. Learn more at
