Electrical shocks at Docks

I will give you another issue that is seen and why a marine rating on appliances is becoming necessary.

Most of the cheaper appliances (refrigerators, AC units, can openers, microwave's +++) coming out of China tie the neutral to ground. If the neutral for some reason has resistance or becomes open, that ground becomes neutral. In a boat and that is BAD. There is a cases where the ground from AC was tied to the 12DC ground, and I bet that there will be a HUGE payout for that blunder.

Now, this really sucks because there are hardly any portable generators that have the marine stamp because of this very issue. If you use a portable generator on shore and connect it to your houseboat be Very Very careful.

An ELCI ( Equipment Leakage Circuit Interrupters) safety breaker will help. After reading and learning about the issue, I installed one on my boat, because I wanted to be sure my kids were safe in the water around my boat. Soon I will be adding an isolation transformer<-- really the only way to prevent this problem.

Lots of good points here.

I still think the risk is very very low of electrical shock at these marinas. And a simple device on the dock could make sure it was known the second it happened.

If I could add a detector to my dock to get the ability to swim by my dock, I would do it. I bet there are others that would also. This way the marina gets a free system of early warning.

I think the no swim rule is just some rule makers getting scared of what the don't understand. There are plenty of lakes around the country and world that have solved this problem.

Hi Mike,
I purchased one of these last year and it works... Cheap insurance if you ask me.

AS for Aramark they are going to push the issue to to the boat owners, and if what I am hearing is correct, you are going to have to install an isolation transformer in the next few years.

How much was it? I used the link and any link on their site was not working.
 
The attached inspection of the electrical systems on the docks at Lake Powell was completed in 2014. Does anyone know if the problems cited in the report were corrected?
 
A report from 2014 really does no good as they have changed things, at Wahweap anyway, last year. Inspections should be made on a schedule that includes routine and expansion/changes. The systems are only as good as the last inspection especially in a dynamic environment.
 
We spent a week at Table Rock Lake next to Branson, MO last summer. Boats slips galore - hundred of them- everyone swims from them, some even have a lower "beach" or slide built onto them.

I say for Powell - get the docks fixed.
