The Megger LRCD200 series of combined loop and RCD testers provide simple, affordable and flexible test tools for electrical contractors testing energised circuits.

All LRCD200 series instruments are supplied with a calibration certificate and come with the new Megger electricians tester case, providing tough rubber armouring, built-in front cover, weatherproof to IP54 and easy-to-use functions and layout. The instruments can be hung around the neck or hand held and will not slip if placed on a bench or shelf. Test leads can remain attached with the front cover open or closed. L-N-E connection indicator LEDs show connection status and reverse polarity supplies

Three instruments are available:


This instrument provides three-phase safe non-trip loop testing and 1/2I, I, and 5I RCD testing for standard, selective, and DC RCDs. Suitable for domestic installers testing to UK Part P requirements.


This does everything the LRCD210 does with the addition of 110 V loop testing and two-wire fast testing, plus phase-to-phase and phase-to-earth/ground measurement and automatic RCD testing with result recall. All instruments will not trip RCDs rated at 30 mA or greater during loop testing, even electronic RCDs.
