"If that were true Glendinnings would be burning down boats and burning out cords left and right. And that ain't happening."

Sorta like all the gasoline boats that are exploding everywhere!

In theory, that is true (the coils become a transformer of sorts). In practice, not so much. The solution is simple - don't coil the excess cord, snake it around on the dock.

It's good that the marina takes electrical safety seriously because most do not.

Back on topic, I have both a 50' cable and a 40' cable. 40' cable you say? Where did you get that and why?

I had a 30' cable that was weathered and the ends were suspect so I went to West Marine. They were having a closeout on 40' shorepower cables for $35 each. I quickly bought one. I should have bought two.

The 40' cable works most of the time (and the excess is coiled up ant my home marina). Bow in, I usually have to use the 50' cable. If you travel, you need options. I also have a 50 amp and 20 amp adapters. I've never used the 20 amp, it came with the boat.

That is beyond insane,, as the best plugs are not molded on.

I can see them requiring marine ends and WP covers to match to the power pole , but REQUIRING a lesser grade?
The issue is not the quality but the fact that a factory end is pretty much guaranteed to be wired correctly while a user installed end could be wired incorrectly. Not everybody understands that the wires have to be in the correct positions. As simple as it might seem to do, I have encountered cords where someone has gotten it wrong and created a pretty serious hazard.

I have wired several. Unless there are other, non-standard brands available elsewhere, all the plugs I have found have been accurately colour coded. Back, White, Green. Even a colour blind guy will still get it right.

And as a former musician, I found myself playing outdoors many times with a venue supplied extension cord that failed my little portable tester. I remember rewiring both ends of a cord at a country club before we could play safely

I remember watching two guys (school custodians) replacing an electrical outlet. They weren't concerned with the color of the wires, they were using which side of the outlet the original wires were on. That gives only a 50% chance of getting it right depending on which way they were holding the outlet.


The AV guy at the school I worked at was trying to replace the cord cap on an extension cord. He complained to me that the wires wouldn't stay in (he did have the colors right). I had to tell him to tighten the screws. He thought they should stay in by themselves.

In the real world, there are people who will fail even the simplest tests.

But people bad enough to wire their shore power wrong can easily do so inside their boats and it may not ever be picked up...even with multiple surveys and owners.


The world surrounds all of us with dangers everyday.


Insurance companies grow rich figuring out just how bad we all really are at protecting ourselves and belongings.


It would take a marina 15 minutes TOPS to check a power cord to see it is wired correctly.....OK...charge me $25 bucks at a home marina for it or include it in the slip rent. Cheaper than a new cord and if insurance companies are giving rebates to some for Smart plugs...they don't seem too worried but marinas are?


Actually not too much as I have yet to have an issue at a marina with an aftermarket plug...but I guess there are some.

Have a fifty-foot cord. Twenty-five would be sufficient at home berth, but fifty-foot was just barely adequate at some transit docks.

Ted,
This summer, we had MANY docks where we needed 50' and in several I had both of my 50' 50A cords, my Y and both of my 50' 30A cords. If I had another 50' cord, I would consider making a 30' and 20' 50A cord.
I have a 50A input on both the bow and stern.
I am working now to figure out a solution to allow us to run on a single 30A when that is the only option ( we found that in two locations over the summer). Currently our ISO-Boost will not allow the boat to accept anything but 50A.
I did not see this thread in the fall or I would have commented then.
Cheers,

That's what I found.
I have 50ft in my Glendenning Cable master. I've just purchased an 80ft cord to install in place of the 50ft.

We have three 50' 50A cords and two 50' 30A. This seems to work for us, especially in the Bahamas when you sometimes have to goto the pedestal at the next slip.

Cheers,
Henry,

My panel is now setup where I can use any number of adapters to run on either 125 or 250 volt service with cords for 50 amp, 30 amp, or even 15 amp service. While in the refit process, the boat was usually plugged into a 125 volt 15 amp outlet. Sometimes simpler is better. With the more efficient air conditioning units and all LED lights, it can easily be run on 30 amp service and carefully on 125 volt 30 amp. Plan to have extra cables for the Loop trip.

Ted

Sorry, but I disagree. Most will get it right, if attention is paid, but I have seen just a few too many where it was done wrong. No one got seriously hurt but it could have been otherwise.

If you understand even a little you will likely get it right but there are those that have NO understanding of the whys and wherefores and thus get it wrong.

Do your own sure, I'm not one of those who feels no one but an electrician should be able to do anything, BUT make sure you do know the requirements even if you do not truly understand all the reasons.
Otherwise someone could get hurt.

"I had to tell him to tighten the screws. He thought they should stay in by themselves."

There actually is "push in" electric stuff at the Big Box stores , saves contractors in a hurry a few seconds.

BUT they use solid wire not the expensive tinned multi strand wire of most boats.

A wire end dipped in solder might be safe for push ins.

Might even help the 30A and 50A dock plugs that get overloaded and melt in high use .

I replaced the 30A inlet on my boat. The instructions stated specifically NOT to solder the wires before inserting them into the connectors.


Sometimes, reading the instructions helps, even if you've been doing this stuff for years.

I could be wrong but I'm pretty sure FF is talking receptacles...not shore power stuff.

Shore power stuff isn't push in lock....

The takeaway here is how much easier life is with a short cord and the boat wired for fore and aft power entry.

Its only a PIA to do once .

You need a switch to select the inlet. Otherwise, the pins on the unused one are hot and a safety hazard. Also, overcurrent protection is required within ten feet (measured along the cable) from the inlet so you will most likely have to add a fuse or circuit breaker panel for the additional inlet.

57 posts to determine the length of an electrical cord.
And some of you guys even know the brand name of the cord.

I thought electrical cords were about as regulated as aircraft nuts and bolts.
I just plug mine in and keep it from being a tripping hazzard.

You really should check the ends for burns and signs of arcing and for excessive heat when running heavy loads like heat or air conditioning for extended periods.
