The new Megger two wire earth loop testers verify the loop
impedance of a live electrical circuit, ie without the need to disconnect the electrical supply. The new LTW425 series
instruments offers a high resolution 2-wire loop testing solution that does not trip 30 mA RCDs and can be used on a wide range of voltages.
