It's sarcasm. It is true though.

As for people getting the colors wrong, don't laugh, I've seen it done many times. I've also responded to a guy who wondered why the wires kept coming out. He didn't know you are supposed to tighten the screws. Seriously.

He had a college degree.

Perhaps a better option than coiling them would be to dangle the excess in the water so that they can be kept cool.

OK, I confess: I Googled inductance and coiled wire. Y'all can, too.

I wanted to know whether hanging the coiled shore power cord in the water would keep your slip ice-free.

Just buy a short cord and be done with the hassle...https://www.amazon.com/Amp-Power-Cor...ord&th=1&psc=1
I bought one of these for my Standalone 2K generator hook-up.
Keep your long cord on the boat for traveling.....That will definitely prolong it's life.

12', $48

I have experienced the heat build up in a coiled cord. But never in a large shore power cord.

Not to say it can't happen. My guess is it happens only if the cord is under a high amp load.

Ok we've got a coiled wire with AC current flowing through it. Can we make an armature spin or maybe magnetize a screw driver?

You can demagnetize the screwdriver. Or a VHS tape.

My theory hat is a little dusty but I believe that since the two current carrying conductors are parallel with opposing current directions, the generated inductance of each would be equal and opposite resulting in zero. Confined heat (tight coil with inadequate airflow) from voltage drop can cause overheating & melting of the insulation.

A nice loose coil on the dock shouldn't be an issue but I would make up a short cord. Cleaner dockside and minimal voltage drop.

Since we bought a new cord, we use the old one as an electric blanket to warm the bed.

How about those yellow Cord Pro Reels for shore power cords I have one and have used it often. I never noticed heating of the cord but never checked for it either. In my case most of the cord is usually unwound when in use, but I can see if a power post is close to the inlet on the boat a good bit of the 50' cord could be wound up in side.
here is a link to their site http://www.cordpro.com/cpxl.html

Nope... This is actually a thing. In the theater and on concert tours, we have to figure 8 the feeder lines to prevent them from overheating. Is there enough to do it on your boat? Maybe or maybe not. If you have a long extension cord on a spool at home, plug it onto a large load. Something that pulls a good 10 amps and let it run for a little while. Come back and check the spool... it WILL be warm. Partially just from the high amperage, but also because of the creation and collapse of the magnetic field creating inductive current into itself.

I hope this is just a joke. Shore power cords in the water are the number one cause of stray current in marina's. This is an absolutely horrible suggestion.

If it's a joke, try a smiley face emoticon or an LOL or something.

As far as leaving shore power cords behind on seasonal or long term slips, please remember to turn the power off at the post when you leave. Don't leave a hot shorepower cord sitting on the dock. This is in case it rains or someone accidentally kicks it into the water.

Rest assured it was not a serious comment.

I didn't think anyone here would actually read that and think it would be a good idea.

I don't believe that to be true.

Could you sight a source please?

You can put the extra shore power cable in the water to keep it cool, but be sure and tie off a support line so the weight of the cable does not pull on the plugs.
Also you need to be sure and have the correct licenses, depending on how long you stay at the dock. With a long stay you will need a harvest license for clams that are growing on the shore power cable when you retrieve it.
By putting a heavy power load on the cable a few hours before departure you will be able to remove the half baked clams off the cable easier and cook time for the clams in your stew will be shorter. After bringing the shore power cord aboard, wash it off, dry it off and use 303 to bring back the luster of the power cord, as if it was new.
Happy Cruising.








Lol

If you and your friends are allergic to shellfish, would it be ok to antifoul the cord, if so, which antifoul would you suggest?
Seriously, how does electrical current escape a cord partially in the water?

Greetings,
Mr. BK. "...how does electrical current escape a cord partially in the water?"
https://en.wikipedia.org/wiki/Electrical_treeing
Partial breakdown of insulation due to UV or mechanical damage.
