ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Rcd trip times

Gidday Alan,
I use an AVO Megger Installation tester to do my testing of RCD's.
I have seen these results pop up everytime I test.
Over here it has to be under 300mS trip time
at the stated (say 30mA) current.
I think the longest time I have had is 42mS, and that was at 300mA, with a Selective RCD.
