Something like a big bright red flashing LED when it was tripped. Or a SonAlert, or both. (He can send me a couple after those are in production, thank you.)
Unfortunately the thermal breaker needs to be protected, thus it is buried in the potted epoxy so that it can remain reliable. Adding more lights etc. just adds to the cost and complexity of the product and people already complain about the cost.... I suspect when you see no shore power that would be a good indication that either the dock breaker is tripped or that the SmarPlug has gone off on temp...

Actually, that was Edison's assertion...

from AC/DC: The Tesla?Edison Feud | Mental Floss
Quote:
Edison’s least favorite of Tesla’s “impractical” ideas was the concept of using alternating current (AC) technology to bring electricity to the people. Edison insisted that his own direct current (DC) system was superior, in that it maintained a lower voltage from power station to consumer, and was, therefore, safer. But AC technology, which allows the flow of energy to periodically change direction, is more practical for transmitting massive quantities of energy, as is required by a large city, or hub of industry, say. At the time, DC technology only allowed for a power grid with a one-mile radius from the power source. The conflict between the two methods and their masters came to be known as the War of Currents, forever immortalized by the band AC/DC.
I went to the Edison museum last week...

... And now; back to our regularly scheduled program.

Re: Shore Power-SmartPlug vs. 1938 (long post)

We love our 30a Smart Plug system. We have a 75 footer that stays on dock. This one is an end to end Smart Plug product. (they have a number of these 75's in stock but don't advertise them, you can get a good deal it) We took our old cord and added the Smart Plug adapter to it. This one travels with our boat. It also works great. While putting on the adapter kit, the housing cracked. Smart Plug followed right up on this issue and provided a new one. Great service!

I actually went to their office in Seattle as I was in the neighborhood. Really a great group of folks there, all big time cruisers.

Maine-
"when you see no shore power that would be a good indication that either the dock breaker is tripped or " Absolutely. Assuming you know that's not just another fancy power cord. But if the person stumbling about in the dark doesn't know about that cord, or has forgotten about that cord...The great idea becomes an added problem instead, as they stumble about trying to figure out what is happening. No doubt the cost is always going to be a problem but at least cost is a visible one. (G)

eh-
Thanks! All the Ac current in the walls surrounding me, has ruined my memory.

I suppose, if SmartPlug could work out a really aggressive patent licensing arrangement, so that "anyone" could use their design as a standard, that would open the door for insurers to give discounts to marinas installing them on poles, which in turn would open a door to replacing the existing standard.

I had a Smart Plug installed on my Tartan 40 three years ago and have been very happy.

Re: Shore Power-SmartPlug vs. 1938 (long post)

I have Glendinning cable retractors on the boat, so my boatside connections are solid (I think). I do have traditional 30amp (2x) connectors for the pedestal on the dock. I've melted one off and shorted another. I'm getting pretty good at cutting the cable a foot back and installing a new connector.

What choice do we have, but to use these shoreside connectors? I've never seen a pedestal with a smartplug connector.

The shore side standards were just re-written to allow for the Smart Plug (previously required them to be "twist-lock") and you can expect to see a shore side based plug in a year or so. If you have a good marina hopefully they would allow you to install one for your slip. For now just stay well below 80% of the 30A and keel the terminals clean.....
