What is a ground wire and why is it important?


 Ground wires: a necessary insurance

Harnessing electricity as a source of energy is undoubtedly one of the most revolutionary achievements in human history. And while misused electricity can be dangerous, electrical engineers have incorporated several safety devices into the home power grid that will keep your home and property safe from potentially deadly electrical shocks and fires. 

What is a ground wire?

Electricity, in essence, is predictable; positively charged electrical energy always seeks the fastest path to the negatively charged ground. Electrical impulses from a home grid also move along the fastest path to earth, but electrical engineers have long since figured out how to manipulate that path to harness electricity to power our homes. However, power grids often suffer from surges and arcing that cause excess electricity to seek a new path to the ground. This is where the grounding cable comes into play, designed to provide the excess electricity with a safe and efficient path to the ground.

What are the different types of ground wires?

Since the purpose of a ground wire is to safely channel excess power to earth, almost all are made of highly conductive copper wire, wrapped in a green and yellow plastic installation, for easy identification. The color of the ground wire, green with a yellow stripe, is almost universally used to help identify the ground wire from other electrical wires. There are some aspects of ground wires that may differ depending on the needs of the electrical network you are grounding.

Are you concerned that your electrical network is not properly grounded? 

Proper installation and maintenance of electrical ground wires is a very important part of keeping your home safe.
