Why is earthing essential?
Earthing is a crucial component of any electrical installation. It ensures safety by evacuating leakage currents to the ground, protecting occupants and electrical appliances from electric shocks, power surges and short circuits. A grounding problem can therefore represent a major danger for your home and its occupants.
Signs of a grounding problem
Electric shock
If you feel slight electric shocks when touching appliances or plugs, this may indicate poor earthing or lack of protection.
Earth leakage circuit breakers that don’t work properly
An earth leakage circuit breaker (ELCB) is designed to detect current leaks and cut off the power supply. If it doesn’t react, it may be due to faulty earthing.
Electrical appliances that wear out quickly
Lack of grounding can lead to power surges, damaging your equipment and shortening its lifespan.
Sockets without earth pin
In older installations, some sockets do not have an earth pin, which prevents protection of the connected devices.
Sparks or overheating at the sockets
Signs such as sparking, overheating or unusual plug noises may indicate a grounding problem.
How do I check the earthing system?
Using a socket tester
A socket tester is a simple tool that can be used to check whether a socket is correctly earthed. It also indicates any anomalies, such as reversed wires.
Check differential circuit breaker
- Press the “Test” button on the differential circuit breaker to check that it is working properly.
- If the circuit-breaker does not respond, this may indicate a grounding problem or a device malfunction.
Visual inspection
- Check the wire connections in the wall sockets. The ground wire is usually yellow and green.
- Make sure the ground wires are properly connected to the electrical panel and outlets.
Calling in a professional
If you suspect a problem, it’s best to call in a qualified electrician. He or she will use specialized equipment, such as an insulation tester or an earth resistance meter, to diagnose the problem.
Why can grounding fail?
- Older installation: Older homes may have partial or no earthing.
- Damaged cables : Ground wires can deteriorate over time or be cut by accident.
- Earth spike problems: The earth spike, buried outdoors, may be corroded or incorrectly installed.
Solutions to grounding problems
Repair or replacement of earth cables
- Replace damaged or worn cables.
- Make sure every circuit is earthed.
Installation of a new ground stake
- If the existing post is corroded or ineffective, a professional can install a new post that complies with current standards.
Electrical installation update
- Upgrade your electrical panel by adding differential circuit breakers and checking that all sockets are properly earthed.
- Replace ungrounded plugs with compliant models.
