[QUOTE="us_sparkey, post: 560764, member: 38436"] My understanding of the standards here is they are based on the 'let go' threshold of 6ma but I think the trip time is longer than a traditional 30ma RCD. When the standards were first adopted here for pools in the 1960's it was the same as a 30ma RCD then at some point it changed. I think with shock / ground fault protection for people its more about the miliamps than the voltage or frequency. There is not much different about our system there is lots of 240V stuff here. We just ground (Earth) the 240 in the middle, instead of on one end. These days with electronic drives like VFD's input frequency does not matter much. So in a way were more compatible than ever. Interesting, the 10ma I bet is based on the let go threshold. Cheers [/QUOTE]
