Digital ELCB Tester

Listing ID #3485400

This is a professional socket tester with modern, ergonomic and durable design, to test safety of installed mains socket. It conducts the following functions:Checks socket polarity,Indicates high earth voltage presence, Works as a RCD (ELCB) Tester.
It checks 30mA RCD (ELCB). A unique soft-touch button tests that an RCD (ELCB) in the circuit trips within 300mS when a nominal 20mA earth fault current is applied; another button, the earth volts touchpad, detects raised earth voltages above 50V AC, thus indicating potentially dangerous installations.Three different bicolor LEDs and a buzzer provides a quick to check combination of signals which indicate correct working, missing earth, live neutral reversal, missing neutral, live faults.
