Earth leakage units (RCDs) save lives — they trip in milliseconds when current leaks to earth. They are also wear items. We test, certify or replace earth leakage as part of routine maintenance or COC work.
What we do
Test trip-time and trip-current with calibrated tester, replace if outside spec, certify.
Why earth leakage trips
