Electricity is an indispensable part of modern life. But with widespread use comes increased risk of electrical accidents and fire hazards. 📊 Studies show that nearly 25% of all fires are caused by electrical faults. Without proper safety measures, this number can rise significantly. That’s why earthing systems and residual current devices (RCDs) are critical components in any safe electrical installation.
An earthing system safely redirects leakage current into the ground, protecting both human life and electrical equipment.
A residual current device (RCD) detects imbalances between phase and neutral currents and disconnects the circuit instantly when a fault occurs.
Together, these systems ensure safe operation and protect against electric shock, equipment damage, and fire risks.
Electric leakage can cause serious injuries or even death. 🔍 According to the EN60947-1 standard, any current above 30mA poses a life-threatening risk.
1–5 mA → Mild tingling sensation
5–15 mA → Noticeable shock, voluntary muscle control possible
15–25 mA → Painful shock, loss of muscle control, irregular heartbeat
25–80 mA → Risk of cardiac arrest
80–100 mA → High risk of death
💡 Solution: To protect human life, a 30mA RCD must be installed in residential and industrial electrical systems.
An RCD is a protective device that monitors the difference between phase and neutral currents. When the imbalance exceeds a certain threshold, the device disconnects the power — preventing electric shock and electrical fires.
30mA RCD → Designed for human protection
300mA RCD → Used to prevent fire hazards in electrical systems
When phase and neutral currents are equal, the system operates normally.
If a difference occurs, the toroidal transformer inside the RCD generates a magnetic field that triggers the switch to cut power.
A test button allows users to verify the device’s functionality.
Electrical Internal Installation Regulation: Requires 300mA RCDs at main entry points and 30mA RCDs on sub-circuits
Earthing Regulation: Defines technical specifications for RCD use
Occupational Health and Safety Regulation: Mandates RCDs to disconnect circuits in case of earthing faults
❌ Incorrect neutral wiring often causes RCDs to trip unnecessarily. In such cases, some facility owners disable the RCD instead of solving the root issue — a dangerous and non-compliant decision.
✅ The correct approach is to have the system diagnosed and repaired by certified electrical engineers who specialize in RCD troubleshooting and earthing system inspections.
