RCD Testing
Testing the trip times of RCDs with all commonly found
RCD current ratings.
For most international applications and the UK, 5 tests
must be performed:
1) 1/2 x RCD current rating, to ensure the RCD does not
2) 1 x RCD current rating. This is a trip test to ensure the
3) 5 x RCD current rating. A Trip test to ensure the RCD
4 & 5) both the 1x and 5x tests must be performed at both
All LRCD testers offer:
