Plug-In Socket Tester with RCD

A compact plug-in socket tester that checks outlet wiring polarity and earthing at a glance using a three-LED code, identifying missing earth, reversed connections, and missing neutral. The integrated 30mA RCD test button confirms residual current devices trip correctly under fault conditions.
