That probably worked great until we started connecting data lines between buildings.

The ground road is located usually close to the main electrical switch. It is either made of copper or copper-coated steel with 8 to 10 feet in height.

The installation is done to the main panel that supplies electricity with an approved ground connection. One ground road can take the load of 25ohms resistance or less. If above 25ohms, it is necessary to have an additional ground rod for overall supply as well as support.

The primary objective of a ground rod is to protect against a power surge. Among the various situations that occur on your electrical system, the most common are high voltage surges, and damage or loss of the Service Conductors.

High voltage surges are often caused by lightning strikes on or near power lines. Besides, the voltage failure can occur when large appliances or heavy machinery at nearby locations are frequently switched on or off. Proper grounding provides stability to your home’s electrical system and reduces the impact of such power surges.

Call your nearest electrical installation service to help you install and suggest the ground rod to protect your residential space from sudden electrical issues.
