for your viewing pleasure, i post the following photo...

this morning, i had to provide shore power for a 125' yacht in
for refit at a marina.... the plan was a construction spider box
on the foredeck, with a 50 amp cord down to the dock box.

plan meets reality:

6-4 SO cord is bare, so off to the wholesale house i go.

i leave the spider box on the foredeck, the 6-4 tied off
to a bollard and fed thru a scupper, coiled on the deck
awaiting my speedy return.

when i get back, i find that the boat refitters were in my corner,
helping the project along....

there wasn't a convenient place to put the ground wire, so they
cut it off... they hadn't gotten to the hard wire on the dock box
yet.......

Well that does not look weather proof..:lol:

It's great they cut the ground off,It's not like you need it or anything.:blink:
 
This past summer there were three electrocutions in this general area at marinas. The more I see, the more I understand.

I believe I have read that GF protection for all marina circuits is in the making, perhaps it is proposed in 2014, I don;t recall.

At one time I heard our State was looking at mandatory annual electrical inspections but politics will probably get in the way.

GFCI will do nothing to protect from raised voltages on equipment grounding conductors - which outside of poor or non code compliant wiring practices is probably leading cause of electrocutions in these areas from many of the stories I read. Unlike a swimming pool it is usually hard to install an equipotential grid in a river, lake, stream, an ocean...
 
Watch old temp power cords

Watch old temp power cords

One problem I've encountered is broken internal strands on temp power cords. On one job when power was connected and with a voltage signal from a proximity voltage tester my drill wouldn't work. Tested the voltage and only had 75 volts to ground, due to broken and corroded strands in the temp cable. I cut the cable down to 50' from 100' and only gained about 5 volts ultimately had to replace cable.:eek:

I agree with you completely. You can put all of the ground fault protection you want, but the water is a parallel path for current, and the bigger the VD on the PoCo distribution neutral, the more voltage you will find between the ground conductor and the water.

That's not so say that putting GFP (as in the 2011 code) is not a worthwhile endeavor, it will help identify offending boats or feeders on the dock that have the potential to hurt someone.

It is worthwhile IMO. It will help identify problems like you mention. But not help if unqualified people that don't understand it think they fixed a problem by bypassing the protection, which I can see happening easily.

The limited amount of marinas and even private boat lifts and docks I have been around - I have seen enough to know I really don't want to swim near those areas. If you are in the water, you have no time to react before you are dead, and really have no warning something may be wrong either. In the boat or on the dock you at least are more isolated and have more of a chance.
