Ground wire tester for power outlets, LCD screen, residual current circuit breaker tripping test, polarity and phase verification, AC30-260V 45-65Hz electrical outlet detector

General Description This grounding tester is a multifunctional tool designed to check the safety of electrical outlets. It detects common wiring faults in GFCI outlets, such as open ground, open neutral, phase and neutral reversal, and ground faults. Its clear LCD screen provides easily readable test results, even in low light. Technical Specifications Input Voltage: AC 30-260V Frequency: 45-65Hz Display: High-definition LCD Operation To use the tester, simply plug it into the outlet to be tested and press the test button. It allows for quick verification of outlet polarity and the safety of residual current circuit breakers (RCCBs). If an RCCB is present, the RCCB test button can be used to trip it for testing purposes.
