Bingo. It doesn't take much to detect this, and it's a binary condition: if current is flowing, then there's a problem. If not, then not. > Speaking of which, if you're really worried about safety, start by > changing all the outlets on your boat to GFCI. Exactly. GFCI is sensitive enough and fast enough that you'll eliminate that entire class of problems. In fact, a really good idea for anyone using an inverter on a boat would be to use an in-line GFCI (about $22) - possibly one of the best and cheapest shock-prevention strategies out there. Until John La Grou's "smart power outlets" (EFCI) become widely available (and that'll save a hell of a lot of lives), that's the biggest AC safety improvement you can make. http://www.ted.com/talks/john_la_grou_plugs_smart_power_outlets_1.html (I *love* TED Talks.) -- OKOPNIK CONSULTING Custom Computing Solutions For Your Business Expert-led Training | Dynamic, vital websites | Custom programming 443-250-7895 http://okopnik.com http://twitter.com/okopnik _______________________________________________ Liveaboard mailing list [email protected] To adjust your membership settings over the web http://liveaboardonline.com/mailman/listinfo/liveaboard To subscribe send an email to [email protected] To unsubscribe send an email to [email protected] The archives are at http://www.liveaboardonline.com/pipermail/liveaboard/ To search the archives http://www.mail-archive.com/[email protected] The Mailman Users Guide can be found here http://www.gnu.org/software/mailman/mailman-member/index.html
