mepsnbarry Nope--nothing new. I remember a prior boat which had scorch marks at the AC power inlet. When I was on that boat in a boatyard, I recall seeing two power cords that had died that way.

Somebody linked to a solution to this problem, but from the looks of it, they are getting ready to go into production, and don't have parts available or a price just yet. SmartPlug Systems seems to be trying to fix this. I found the direct link more useful than the boat show video somebody else pointed to on Mad Mariner. If this becomes common, I'll be happy...except for having to buy new cords and re-do the connection on my boat.

Spiritman That's a good point. But I've always been very careful about connecting/disconnecting the power cord -- at both ends -- and often check for corrosion.

No better time to redesign the standard?

scottyt for some strange reason on house wiring it normally the neutral that causes problems but not all the time.

that burnt end is not due to water it is simply high resistance be it from corrosion or a loose connection. i think what might help cause this is how tight the socket is. if its real tight you have to wiggle the plug loose, and i mean the rubber part being too tight. when doing the wiggling you stress the contacts and open them up, next thing you know is its a loose connection

sailortjk1 Wow, maybe Brian wasn't crazy after all.
I think this is the Third Thread I have seen on this same subject.
You are not alone.

Spiritman Yes, it was the hot pin that was scorched.

sailingdog I think that looks like the hot leg, but I'd have to look at the cord on my boat to be sure.

hellosailor I think they'd need some seed money to give away a couploe of dozen thousand of them to major marina chains, in order to prime the pump and give boat owners a reason to buy them. And then, other marinas a reason to use them.

Or convince insurers that they are so much safer, marinas using them deserve an insurance break big enough to cover the cost of buying them.

Sure looks like a better mousetrap--but the old mousetraps are long bought and paid for.

My dock neighbor is the inventor of that product. Saw it at the the trade show a few weeks back (didn't know it was my neighbors that invented it until then). Solid product and well thought out. The only drawback I see is the price and the fact it is basically worthless if the marinas shore power doesn't have their style receptacle. They do have an adapter plug for marina shore power to their system but in my opinion - kinda defeats the purpose. I regularly get reverse polarity when the shore power cable gets jiggled a bit as at my marina they do not have the type that allows the screw / secure thing...However nice product and the design is solid - just with the economy as it is - I think it maybe one of those inventions or "new" ideas that never make it mainstream.

Spiritman Thanks for your input everyone.

That SmartPlug system seems to have addressed all of the problems in the now 70 year old (70 years!!) design standard that we use today. I'm definitely going to investigate it.
