UNI-T UT07B-EU Socket Tester

Description

UNI-T UT07B-EU Socket Tester The UNI-T UT07B-EU socket tester is a compact plug-in device designed to check wiring correctness in AC mains outlets. You insert it into a standard European socket, and its LED indicators light up in various combinations to show whether the live (L), neutral (N), and earth (E/PE) connections are correct, reversed, or missing. It makes wiring verification fast and intuitive by eliminating guesswork. Beyond basic wiring checks, the UT07B-EU includes an RCD (residual current device) test function, allowing users to press a button that induces a small leakage current (approx. 30 mA) to verify whether a protective device (RCD) will trip under fault conditions. This extends its usefulness from mere wiring diagnostics to safety verification of protective devices. The housing is molded from durable plastic and sized to be portable, with LED status lights clearly visible on its face. In use, this tester becomes a go-to tool for electricians, installers, safety inspectors, and DIYers who want a quick, non-intrusive sanity check of socket wiring. It helps detect common wiring faults missing earth, reversed live/neutral, absent neutral, or incorrect phase orientation before connecting sensitive or critical equipment. Because of its simplicity, it’s also useful for preliminary safety checks in homes or sites without needing to bring out a full multimeter or tester kit.
