The Grounding Tester, in addition to checking if you can perform an Earthing practice at home, also checks the current part of the socket (phase and neutral).
We detail the different indications of the Earthing ground tester:
LED Indicator | Technical Description | Professional Recommendation |
---|
⚫🔴🔴 (Correct) | Proper installation and active grounding. | You can use this outlet with complete confidence to connect your Earthing devices. |
⚫🔴⚫ (Open Ground) | No ground connection. | Find another grounded outlet or request an electrician’s inspection. Without grounding, no benefits will be obtained. |
⚫⚫🔴 (Open Neutral) | No connection in the neutral conductor. | Find another outlet with an operational ground or have an electrician check the installation. |
🔴🔴⚫ (Live/Neutral Reverse) | Phase and neutral reversed, something common in some installations. | Unplug the tester, rotate it 180°, and plug it back in; in most cases, it will show “Correct”. It does not affect safety or operation if the ground is present and in good condition. |
🔴⚫🔴 (Live/Ground Reverse) | Phase and ground reversed. | Do not use this outlet. Look for one with correct grounding or have an electrician fix it. |
🔴🔴🔴 (Possible Electrical Fault) | Anomaly detected; there may be grounding but with irregularities. | You can use it safely from a safety perspective. However, to guarantee 100% of the Earthing benefits, it is important that the ground connection is optimal and of good quality, something that should be confirmed by an electrician if possible. |
If you notice any anomaly in your home’s electrical installation, we suggest contacting a professional electrician for an appropriate evaluation and solution. Your home’s safety is paramount, and an expert can ensure a safe and efficient electrical environment.
In Europe, most homes incorporate grounding systems in accordance with building regulations.
This mandatory regulation, in place for over 50 years in construction, is considered essential to prevent electrical accidents and ensure a safe and functional domestic environment according to current European Union standards.
