FAQ
How do I know if my socket is wired correctly?
Simply plug the tester into your socket and check the light pattern.
The indicator lights will instantly show whether your live, neutral, and earth wires are correctly connected — no technical knowledge needed.
Do I need to turn the power on to use it?
Yes — the socket must be powered for the tester to work.
This allows it to accurately detect wiring faults and confirm your grounding connection.
Is it safe to use if I’m not technical?
Yes — it’s designed for complete beginners.
There are no settings, no setup, and no risk if used correctly.
Just plug it in and read the lights — it’s that simple.
What if my socket shows a fault?
If a fault is detected, we recommend contacting a qualified electrician to fix the issue.
Do not rely on that socket for appliances or earthing products until it has been checked and corrected.
Do I need batteries or charging?
No — the tester is powered directly by the socket.
- This means:
✔ No batteries
✔ No charging
✔ Always ready to use
