The Megger LRCD200 series is the latest generation of combined non-tripping loop tester and RCD test instruments that provide simple, affordable and flexible test tools for electrical contractors testing energised circuits.

All LRCD200 series instruments are supplied with a calibration certificate.

Two 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.


As the LRCD210 with the addition of 2 wire fast testing, plus phase to phase and phase to earth measurement.

Both instruments will not trip RCDs rated at 30 mA or greater during loop testing, even electronic RCDs.
