I'm trying to make sense out of the ELCI/RCD stuff. Very difficult. n the marine marketplace, what's actually available? Blue Sea Systems seems to have units available now. The Hubbell/North Shore/Airpax-Sensata/Techsol solution does not seem ready to go yet. Blue Seas is physically large. Hubbell/NS/Sensata is better. Legarnd and the EU solutions appear to be a current transformer and breaker in a single unit. Based on your experience and your industry knowledge, can you provide a list of manufacturer's and products that are actually available and meet ABYC, E-11, 2012 for retrofits - not new construction - retrofits to existing boats, as of 1Q2013?"
