For Sale: Shore Power Cable, 10-3 Marine Grade

[Snows]

I have 27 feet of this Ancor Marine shore power cord with a female 50-amp connector on one end. West Marine has it priced at a little over $9/foot, but I don't think the stuff is worth nearly that much. I would like to get $100 for mine, and I'll include shipping in the 48 states.

No takers at $100. How does $50 plus $10 shipping sound?

I don't want to rain on your parade, but:

New Marinco 30A Shore Power Cordsets, complete /w both ends (sealed):
25' @ $85 ($3.39/ft including 2 ends)
50' @ $95.99 ($1.92/ft including 2 ends)

For further rain: 10/3 is rated to only 30 amps... the 50 amp connector would exceed the capacity of the wire and be a fire hazard.

Oops, I missed that. Good catch, Capn.

Lest you all suspect me to be a total idiot, I will respond and help remove all doubt.

I was fully aware of the price of new shore power cordsets when I posted the ad. I too questioned in my own mind the obvious disparity between the cost per foot of Ancor cable at West Marine's website and the cost of cordsets, but concluded that others with more brilliant minds than mine would recognize the not-so-obvious value of this particular cable. I only know what I know, and will readily admit that I don't know what I don't know. I'm now beginning to wonder if the price shown on West Marine's website may be a misprint.

I was also fully aware that the 10-3 cable is only rated for 30 amps. I wasn't trying to dupe anyone with the previous owner's use of a 50-amp plug. I merely offered up something for sale that came as surplus to me. I suppose I should have removed the plug from the cable and listed them as two separate items for those who are electrically challenged. Again, in my ignorance, I allowed for the possibility that someone might actually have a particular application that would call for a 50-amp plug in a 30-amp circuit.

"the 50 amp connector would exceed the capacity of the wire and be a fire hazard" is only true if the 50-amp connector is plugged into a circuit that is capable of producing 50 amps.


How very fortunate we are to have the likes of those who have posted here to educate us on the true value of items listed for sale.

Hey Snows--welcome aboard--and don't sweat it.

Since a 50 amp plug is only compatible with 50 amp plugs...

But one should not assume that a 50-amp receptacle is necessarily connected to a 50-amp circuit. A 50-amp A/C receptacle may not even be connected to an A/C circuit. A 50-amp A/C plug may plug into a 50-amp receptacle that is connected to a nominal 12-V D/C circuit.

And a satellite might fall from the sky and sink your boat! Lets suffice to say that statistically a 50 amp receptacle is connected to a 50 amp, 240VAC supply.

Normally I don't crap all over a classified ad, as I consider it poor form, BUT when the ad lists something that is life threatening to an unsuspecting member, I am compelled to do something out of habit from my career. Not all that long ago I crapped all over a guy selling "brass" ball valves as seacocks.
