Earth Ground System for Electrical Services
Understanding the Importance of an Earth Ground
Requirements for Grounding a Residential Electrical Service
Rick, a earth ground is required for any electrical service, however there are a variety of approved methods for the source of the earth ground and bonding. The most typical way to provide a earth ground is by using an approved ground rod, and there are a few to choose from as well. To understand what is required for your exact location it would best to consult your local building department and the electrical utility provider provider who usually have a typical specification sheet that they will provide helpful for you.
The Importance of a Earth Ground For Safety
When installed properly and according to electrical codes the earth ground serves as the bond for electrical equipment and enclosures to the earth ground source so that if there is an electrical failure, electricity may be sent the the earth ground source, where in most cases and by design, will cause an over current device to trip off or open the circuit which will stop the supply of electricity to a location of the electrical failure.
The Importance of a Earth Ground For Electrical Service
The earth ground is also an essential part of what is known as the Grounded Neutral, which is the required return path to ground for 120 Volt circuits, also a part of the 120/240 volt home electrical service.
