using shore power on boat with no A/C

we have several boats that have no shore power connection on their boats, can a extension cord from our dock 30 amp box, using marine grade 12/3 wire with a ground fault device to power small electrical devices not exceeding 10 amps be used. max cord length would be 25 feet.

I use normal 'on a reel' garden extension cords all the time on my boats.. have even run a 2 bar heater of them.. when the marina has not had an output breaker at the box..

I see no issue with that setup other then ensuring you use stranded cable

Re: using shore power on boat with no A/C

Yes you can. I have done this several times as our dock box has a 30 amp and a 50 amp plug in, and we normally only use the 50 amp. So when high amps, I have an shore power adaptor that a regular power cord can be plugged into. They cost about 30 bucks.

Re: using shore power on boat with no A/C

There is some risk in using light extension cords with a shore power adapter on a 30A dock outlet. The 30A breaker on the outlet is sized to protect a 30A power cord. If you use a cord rated at, say 15A, and wind up with 20 or 25 Amps total load on it, the cord will overheat without tripping the breaker.

If you are plugged into a 15A outlet with a 15A breaker at the dock, there is no problem.

i use the marine cord to the shore power outlet on dock, then an adapter to 3 prong with surge protection to my appliances and computers. is inconvenient, but ..... my ketch is wired 12 v primarily. i am rarely in a slip, except for summer, which is furycame season and repair season.
mebbe if i am good enough,or not, santa may wire the 120v outlets so next summer i can simply plug in for a bit..lol
