    The interesting thing I see on Marinco's web site is that most of the power cords have the UL CSA symbol displayed on the product page. None of the pigtail or Y adapters do. Wonder if this is an oversite on the web design, or more likey they can't get UL CSA approval for the adapters. Hmmmm sould be interesting to see it they reply to Franks email.

    Asked and answered. What if there's a fault in the wiring inside the boat between the inlet and the breaker panel? Not a dead short that would kick out the 50A breaker, but enough to draw 35 to 45 amps. The 50 wouldn't trip but that 10 gauge wire, which is only OK for 30 A, would sure get hot.

    Read you own edited by me post...and if it does exceed? Even that being said, you are still only protecting a 30 amp device (shore power cord and boat up to main panel on boat) with a 50 amp breaker.

    No. Just checked my email. Now I'm sure that someone in mangmement and maybe even legal threw a fit. They'll never answer because there is no right answer. If they say it's OK, when it's a clear NFPA NEC 70 code violation, then they open themselves to all kinds of legal problems if an electrical fire results. If they say it's not OK, then why are they selling them? Finally, there is the last possibility, that it's OK and not a code violation, in which case, why not send a response saying it is not a code violation because of XYZ?

    Be on the watch for a DomAdapter with built-in 30A circuit breakers to be put on the market really soon now.

    Best regards,

    I am on record as wanting a copy of the book and an adapter as well. Just wondering since the book was promised to us "first part of may" or something close to that, we should start a new poll......Which product hits the market first?
