Testing RCDs
Various test and measurements are required for verification of RCD(s) in RCD protected
installations. Measurements are based on the EN 61557-6 standard.
The following measurements and tests (sub-functions) can be performed:

Contact voltage,

Trip-out time,

Trip-out current and

RCD Auto test.
