Now that's silly.... I ain't never in my life seen dry ground unner a boat slip... 'cept in the drought of 2007.
I'd be willing to bet a fair amount of money that if you cruise all 500 miles of shoreline of this lake you'll not find the first EPG. And if a compliance officer or inspector did the same thing looking for code violations he/she would spend the rest of his days writing citations and going to court for this lake alone.... much less all the river and tributaries between here and Mobile bay in the Gulf of Mexico.
The reason why there would be no grounding grid is because there is no requirement to install one under a metal dock. Most people with a little common sense know better than to go swimming in waters such as these in the first place
Lets not let this thread die, It is good, and long lived. (Thanks to Terry and the Group)
Did the problem ever get resolved ?
Real Ships connect to ShorePower when they pull up to the docks.
Not only does it put the boat at the same potential as the Power Ground it also discharges any Static Electricity,
that the sacrificial anode does not.
Look at how boat docks that have gas pumps are wired, They have the same threat as Humans when it come to safety.
And also "Theory only works in a vacuum" , there are just to many unknown variables in every day life.
Here is a question for You, Does a light give off light or does it suck up dark ?
I would like to see a thread on RF, where the Earth Ground is everything, And it can carry big time Current. (Must be FM)
Have a Great Day.
Want a thread on RF, grounding, FM ... start one!
If the POCO had never connected neutral wires to ground rods then the stray voltages from the power company sources would not be entering earth. As I understand it, some power companies are running only one wire but depend on the earth to carry the return current. I've not been concerned enough about it to think about this very hard...
Hello Randyj and the group,
Very good on your answer Randy. Light does interfere with astronomy, That is why stargazers go to the county for a good view.
City lighting is a big problem. Light Clutter is one name for it.
I have seen the bashing that you have gotten.(Call it what You will, I am not a book worm, Nor want to be.) Don't think nothing of it. Some people have Book Smarts but No ability to apply what is in the book, In the World we live in. They are smart, but contrary to popular belief, They do Not know it all.
Nobody knows everything, Or their Head would be so big for the brain to hold all the information, That is needed to be a Mister Know It All.
The fact is that Opposites attract.
Grounds can kill, If your potential is Above OR Below Ground, when you come in contact with something. Only takes Milli-amps, but also
Voltage is needed (for Your skin to Conduct). A good example is to go across a 12 Volt car battery and you don't feel a thing, even tho it can produce many hundreds of amps. Increase the voltage and it can grab A-hold of you even if you do not touch it. (I hate when that happens)
Ground Loops are very common in many electronic systems. (Electric , electronic, call it what you want, Flow of electrons)
Simply a difference in potential. You don't need to be a Rocket Scientist to figure it out.
A Vacuum is mostly available in outer space, and it is very cold. And electron theory is based on ideal conditions, In a Vacuum, Where
electriciy can travel at the speed of light, But only in theory, Not on Earth, Yet.
Electrons will flow mostly in the path of least resistance, but also takes other paths that are in their electric connections.
Lightning take the quickest path that it can find, And will blow something apart if the current get to high for it to be dissipated. (Heat gets involved)
I know that a lot that I am saying, You know first hand, I just wanted to refresh your memory and the others that need too be Refreshed.
Have a great day.

If a tree falls in the forest, and no one is there, does it make a sound?
Yes the trees do make a sound, And the birds and squirrels say O-Shit, and run for cover.
But there is no one but God that ever hears them...
FWIW, you can't measure cold...you can measure the amount of heat (energy) (the less energy, the less heat, the more cold)....similar to light, dark is the lack of light....
Well DonL... the thread was everywhere from very serious to highly entertaining for me. I learned a little and refreshed a lot of things I haven't seriously studied in many years. However, the principles of electron behavior still applies just as it did back then. There is some difference in interpretation in several things. One being the idea that electricity takes the path of least resistance or takes the shortest route to source. I think that though lightning is not the same as generated AC or DC since it is static electricity it still shows the fact that electricity can and will take several paths and is analogous to stray voltages... and as far as I'm concerned shows the path of least resistance. The only time I know of that electricity takes the shortest route to source is when it is in a wire and that is the only time it will follow a straight line unless maybe you want to consider an arc such across a spark plug gap or getting zapped by an electric fence... and that is also an example of one wire carrying a current or charge while the ground acts like a conductor. Speaking of electric fences, they work by using a capacitor to store electrons and a 12 volt source can and will knock you on your ass when a capacitor discharges through you in which an electric fence does just that. When I was a kid we used to have fun by charging up a condenser out of a car then handing it to a buddy and telling him to see if it's any good.... It was fun to watch'em jump... pee in their pants if they were drinking..
