Earthing Systems for Building

Earthing Systems for Building, Why TAKO Since 1979?

Earthing systems are crucial parts of buildings. They keep us safe from short circuit, electrical faults and reduce the risk of lightning strikes. These systems redirect extra electrical current into the ground. In this article, we’ll discuss earthing systems for buildings.

Importance of Earthing Systems for Buildings

  • Proper earthing is vital for protecting people and property from electrical faults and lightning strikes.
  • They maintain the electrical integrity of a building’s infrastructure.
  • The systems prevent the assemblage of excess voltage.
  • They ensure the smooth functioning of electrical equipment. It prevents damage to electrical equipment.

Types of Earthing Systems

Rod Earthing

Rod earthing involves driving metal rods into the ground near the building and connecting them to the electrical system.

Plate Earthing

Plate earthing utilizes metal plates buried in the ground to provide a low-resistance path for electrical currents.

Pipe Earthing

Pipe earthing involves using metal pipes buried vertically in the ground to provide a grounding connection.

Strip Earthing

Strip earthing utilizes metal strips buried laterally in trenches to create a grounding network.

How Earthing Systems for Building Works

Components in the Systems

The systems use metallic parts to attract fault currents or lightning.

Earthing Electrodes

Conductive elements like rods or plates establish a connection with the earth when installed in the ground.

Earthing Conductor

The earthing conductor is a conductive part and is a metal wire or strip. It connects the electrical system to the earthing electrodes.

Earthing Pit

Experts excavate holes in the ground to install and connect earthing electrodes, creating earthing pits.

Earthing Tape

Earthing tape is a flat, flexible conductor used to connect various system components.

Installation and Maintenance


The installation of the systems involves several steps, including:

  1. Site Survey: Assessing the site to determine the optimal location for earthing electrodes and pits.
  2. Excavation: Digging trenches or holes for installing the earthing electrodes and pits.
  3. Installation of Components: Placing the earthing electrodes, conductors, and other components in the designated locations.
  4. Connection: Connecting the earthing electrodes to the electrical system using appropriate conductors.
  5. Testing: Conducting tests to ensure that the system functions correctly and provides adequate protection.


Regular maintenance is essential to ensure the continued effectiveness of earthing. This includes:

  • Periodic inspections to check for signs of damage or corrosion.
  • Testing the resistance of the system to ensure it meets safety standards.
  • Cleaning and repairing any damaged components.
  • Upgrading the system as needed to accommodate changes in electrical infrastructure.

Advantages of Proper Earthing

Properly designed and maintained earthing systems offer several benefits, including:

  • Protection against electrical shocks and fire hazards.
  • Prevention of equipment damage and downtime.
  • Compliance with safety regulations and standards.
  • Enhanced reliability of electrical systems.

Challenges and Considerations

Despite their importance, these systems may face challenges such as:

  • Soil conditions affecting the effectiveness of earthing electrodes.
  • Corrosion of metal components over time.
  • Compliance with local regulations and standards.

Common Mistakes to Avoid

Some common mistakes to avoid when installing and maintaining the systems include:

  • Inadequate depth of earthing electrodes.
  • Poor quality or insufficient bonding of components.
  • Neglecting regular testing and maintenance.

Cost Considerations

The cost of installing and maintaining the systems can vary depending on factors such as:

  • Size and complexity of the building
  • Soil conditions
  • Quality of materials and installation

Regulations and Standards

In Malaysia, rules and standards control earthing design, installation, and maintenance. This is to keep electrical installation setups safe and dependable. The regulations and standards are:

  1. Malaysian Standard (MS): This set of rules is MS IEC 60364. It gives instructions on designing, setting up, and maintaining electrical systems, including earthing.
  2. Energy Commission Regulations: The Energy Commission (EC) in Malaysia oversees the energy sector. It sets the rules for electrical systems to keep them safe and reliable.
  3. Surahanjaya Tenaga (ST) Guidelines: The Surahanjaya Tenaga (ST), also known as the Energy Commission, offers guidelines and technical details for electrical systems, including earthing.
  4. Electrical Licensing Board (ELB) Requirements: The Electrical Licensing Board ensures that electrical contractors follow the rules. They set requirements for designing, installing, and keeping up electrical systems, including earthing.
  5. Building and Construction Authority (BCA) Guidelines: The BCA sets out rules for building construction, including electrical work.

Case Studies

Earthing Systems for Building

Case studies highlight successful implementations of TAKO’s earthing and lightning protection systems in different types of buildings, including:

  • Commercial buildings: Office buildings, shopping malls, hotels, etc.
  • Industrial buildings: Factories, warehouses, data centres, etc.
  • Residential buildings: Houses, apartments, condos, etc.
  • Government buildings: Schools, hospitals, libraries, etc.
  • Historical buildings: Museums, churches, etc.

As technology keeps advancing, the systems are also changing. New technologies and ideas are changing how we design, set up, and care for good earthing systems. This will also affect the construction of buildings in the future. Here are some important trends:

  1. Better Materials: Scientists are finding new materials that conduct electricity well, last longer, and resist corrosion. One example is graphene, which is really good at conducting electricity and is very strong. We can use materials like this to make the systems work even better.
  2. Stronger Systems: With climate change causing more extreme weather, buildings must be tougher. The systems need to handle floods, strong winds, and earthquakes.
  3. Using Data for Better Designs: We’re getting better at using data to design and improve the systems. Engineers can make the systems work efficiently by studying the data. They can even use computers to predict problems and plan maintenance, which saves money and makes the systems work better for longer.

In short, the future of earthing is about being innovative, working with other technologies, and handling tough situations.


Earthing systems are crucial for building safety. They protect against electrical faults and lightning strikes. Building owners and operators must grasp their significance, upkeep, and other details to ensure electrical systems’ safety and reliability.


What are the 4 types of earthing systems?

There are four types of earthing systems: plate, rod, pipe, and strip earthing. These systems help to safely release extra electrical current into the ground, lowering the risk of electrical accidents.

What is earthing provided in buildings?

Earthing in buildings is crucial for safety, preventing electric shocks. It means linking the electrical setup to the ground, allowing the safe release of extra electrical current.

What is the earthing system in Malaysia?

In Malaysia, earthing systems typically follow TNB guidelines. These involve using earth electrodes and conductors to connect electrical setups to the ground. This ensures that electrical systems stay grounded and safe for people.

What are the 3 earthing systems?

The main earthing systems are:
– TN-S (separate neutral and protective conductors),
– TN-C (combined neutral and protective conductor), and
– TT (separate earth terminal and neutral).
People choose each based on local rules and specific electrical needs for their respective benefits.
