Ensure your UK sockets are safe and properly wired with this AC Line Fault Detector, the ultimate plug-in tester for homeowners, electricians, and maintenance professionals. Designed for indoor use, this tester quickly identifies wiring issues in 13A UK outlets, helping you spot earth, neutral, and live faults before they become serious problems. The device features a 3-way LED indicator system that clearly shows whether your AC line is all OK, or if there’s an earthing, neutral, or live fault, making troubleshooting fast and easy. Built to last, this tester is made from durable virgin material with a scratch-resistant finish and solid brass pins plated with copper/nickel for reliable conductivity. The glass epoxy PCB board ensures precise readings every time, while the compact design allows for easy portability and convenient use in any indoor environment. To use, simply unplug all equipment on the branch circuit, insert the tester into the socket, and observe the LED lights. Red and green indicate all OK, red indicates earthing fault, green shows neutral fault, red and yellow signal live and neutral issues, and no lights indicate a live wire problem. Important: this tester cannot detect reversed ground and neutral wiring; any faults should be handled by a qualified electrician. This device is perfect for home safety checks, office maintenance, or quick pre-inspections before calling an electrician. Keep your electrical connections safe, prevent equipment damage, and ensure peace of mind with this reliable, easy-to-read AC line fault detector for UK sockets.
