Main Earthing Systems
Do you require a new earthing system for your home? Read below to find out how Darebin Electrical can help you.
Installing a New Main Earth
A fundamental part of every electrical installation is the Main Earth. They are responsible for a pathway that electrical current dissipates through to ground. Reducing the risk of electric shock, fire and electrical equipment.
The system establishes a connection between the homes electrical circuits and the earths conductive surface to effectively create a reference point for voltage levels and a means to discharge fault currents. To request a quote to upgrade your main earth, please click the button below.

It is recommended to have gas heaters serviced every two years to ensure their safety, efficiency, and longevity, as regular maintenance helps prevent potential hazards and maintains optimal performance. Routine servicing includes cleaning, inspection, and any necessary repairs, ensuring that the gas heater operates smoothly and efficiently.
In addition, we also perform carbon monoxide testing during the servicing to guarantee that the gas heater operates safely and does not pose any risk of carbon monoxide leaks, which can be a potentially life-threatening concern.
Issues With Older Wiring And Earthing
- Non-functional or Non-existent Earth Cabling: Older types of cabling, often relied on a uninsulated earth wire running alongside power or lighting circuits. Over time, these cables can deteriorate, leading to non-functional or even missing earth cables.
- Compliance with Modern Regulations: New safety regulations require all circuits to have their own insulated earthing cable. Many older systems may not comply with these modern standards.
- Earthing Connected to Water Pipes:In some older homes, the earthing system is connected to metal water pipes in the house. This method is no longer considered an appropriate primary form of protection, as it relies on plumbing that can be altered or damaged without consulting an electrician.
- Lack of Proper Earthing: If the earth system is not set up correctly, the protective devices in your switchboard may not operate as intended. This can increase the risk of electrical hazards, including fires and electrocution.
- Corrosion and Deterioration: Over time, the connection to the earth electrode may corrode, leading to a poor electrical connection. This can result in the earth system becoming non-functional.
Installation Of Earthing System
The installation of a new earthing system involves the placement of earth rods into the ground at a specific location on the property.
The earth rod is then connected to the electrical system using conductors and bonding. Rigorous testing is conducted to verify the effectiveness of the system, ensuring that it provides a low-resistance path to the earth for electrical faults.
Our electricians can handle the installation to guarantee compliance with safety standards and regulations.
Common Problems With Earthing
- Non-Functional Earth Connections: One of the most frequent issues is a break or disconnection in the earth wire or grounding electrode, which can lead to an ineffective earthing system.
- Corrosion and Deterioration: Over time, corrosion or damage to earth rods, conductors, and connections can degrade the quality of the earth system, increasing resistance to earth and diminishing its effectiveness.
- Inadequate Grounding Conductivity: Poor soil conductivity in the area can result in a high resistance to earth, making the system less efficient. This can be particularly problematic in dry or rocky soil conditions.
- Earthing Connected to Water Pipes: In some older installations, earthing is connected to metal water pipes. This method is unreliable, as plumbing modifications can compromise the system.
- Overloading the Earth System: If the earth system is not designed to handle the electrical load, it can become overloaded, leading to an increased risk of electrical faults and safety hazards.
- Improper Installation: Incorrect installation, such as insufficient grounding electrode depth or incorrect conductor sizing, can render the earth system non-compliant with safety regulations.
- Safety Hazards: When the earthing system is compromised, it can lead to unsafe electrical conditions, including the risk of electric shock and fires in the event of a fault.
