So, the question becomes, can we get European product that will work? I'll go back full circle on all of this to the fact that Our French friends and other have been using shore power RCD (residual current device) 30 mA devices for 15 or 20 years and I have not heard of these nuisance trip problems. So now the question is, will these devices work on a US built boat with US wiring? Will that boat be compliant with ABYC standards? The answer: Yes, ut it depends on the specifications for the RCD device. The ABYC E-11 standard (2013 version) allows for it as long as the voltage and frequency specs for the device match up properly. Basically that means 12 Volts and 60 Hz. The photo below (sorry, not such a good photo) proves the units are available and used.
