To run the boat from 120 30amp is easyLots of ideas
Here are a few responses
- adding a forward ac connection is hard as the boat has a isolator transformer that is in the stern so it would be a long internal cable run through hunters grid system as artboas knows it would just about be impossible in an after market situation
- backing in ... I have no problem backing in and yes then I would only need one cord at my dock but I still need to carry one of the bulky things with me when I leave so it doesn't solve my problem. (and just to clarify one cord is permanently attached to the dock and when I leave I only take one with me)
- running 30 amps as noted by uncledom can cause issues with the set up as the isloator transformer is expecting 220 not 110. it works in a half as_ way and I have to do it some times when I am some place that doesn't have a 50 amp plug ( also I have a combiner which can allow me to get 220 from 2 110 30 amp cords but as noted again by uncledom unless the two 30's are plugged in to different circuits you don't get two phases and I am here to tell you very few marines run multiple circuits down a dock.)
- Al Fooks is working on another problem for me so for now I'm relying on this august group
- do I really need 50 amps some times yes if I have guests and I am running all three a/c units, the micro wave and the coffee pot (you all get the picture I'm sure you have had guests aboard before) but no not always... however that is the way the boat was built and set up.
- I could check with Elon Musk and see if the Tesla engineers could come up with a solution buuuut this is less of an electrical engineering issue and more of an aging guy getting tired of hauling around a 38 pound 4 wire 6 gauge cord with no flexibility.
keep thinking folks I know one of you has a novel idea
Open the transformer, and move the wire from H3 to H2.
It makes the transformer a step up 1:2 instead of 1:1
Half the current obviously, so watch your loads
