There is no effective constant 230V supply and what you get depends largely on the distance from your local sub-station transformer as well as other factors such as electricity demand. The FREQUENCY (50Hz) is very tightly controlled but the voltage is not. In the UK, mains electricity is currently required by law to be delivered at 230 Volts, within a tolerance of +10% / -6%, that is, within the range 253 Volts to 216.2 Volts. The value of 230 Volts is said to be the 'nominal voltage' in an electrical system. Appliances are normally manufactured with this tolerance in mind BUT some devices using switch-mode power supplies (e.g. laptop PSUs) can run from ~100V up to ~250V - this will be quoted on the appliance or PSU (power supply unit). https://www.twothirtyvolts.org.uk/pdfs/site-info/Explanation_230Volts.pdf **Q: Does this device have an audible tone when correctly connected?** A: No, it does not have an audible tone. **Q: Does this tell you if the socket is earthed/grounded?** A: Yes, it tells you if the Earth / Ground is Open, Live and Ground reversed or Live /Ground Reversed, missing ground. Very easy to read and use, there is even a display with the voltage. It also tests the Circuit Breakers (RCD) for the sockets. Good value for piece of mind. **Q: How do I know if my socket is properly connected to the Earth? I want to use an earthing product that requires to use an earth connection plug.** A: You need to be clear in what your asking. This will show you if your socket is wired correctly. Reversal of neutral or live or a short circuit. It will not tell you if the earth is not connected. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does the job! *by V***I on 22 September 2024* The Quille Socket Tester is a fantastic tool for testing electrical sockets.

I highly recommend the Quille Socket Tester for anyone in need of a reliable and easy-to-use electrical socket testing tool. ### ⭐⭐⭐⭐⭐ Handy tool for any electrical *by M***K on 21 October 2025* Handy tool for any electrical ### ⭐⭐⭐⭐ Not great but OK for price. *by S***N on 21 August 2025* Not bad for the price but note that the voltmeter reads about 5v low and the red indicator LEDs are so bright as to be blinding in a low light environment. It will do as a basic simple tester to check whether mains power is present and, hopefully, indicate correctly any wiring faults. ## Frequently Bought Together - QUILLE Socket Tester Mains Outlet Tester with LCD Display Neutral Live Earth Wire Testing RCD Test - UK Plug - KAIWEETS Voltage Tester, Non Contact Voltage Detector Pen, 50V to 1000V AC, Audible and Flashing LED Alarms, Wire Breakpoint Finder, Electrical Tester with Flashlight, Buzzer Alarm VT100 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/79629175-quille-socket-tester-mains-outlet-tester-with-lcd-display-neutral](https://www.desertcart.pl/products/79629175-quille-socket-tester-mains-outlet-tester-with-lcd-display-neutral) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
