Seems to be just 1 reading recorded , the highest of the 3 taken. They should be similar obviously
Usually with SC current and fault loops you're looking for the highest readings

Thanks very much drury, very helpful video. All the the readings of each core are much the same readings.

Another of his tests , on the dangerous end 😁
Bypass the RCD with a high current fault loop test
MCB off and fit a link where you normally would perform the test
