Re: [electricboats] Electric Motor for 40ft Sailboat

Na. Safety wiring regs means you need a registered electrician and "110v wiring rules". But split supply is a border case I suspect.

Consider going with 96v. It's not that much more complicated than 48v but gives you twice the horsepower out of the motor when you need it. Most of the time you won't need more than 5kw. A +48/-48 bipolar isolated system (fuses/breakers & contactors on both rails with the safety ground between the two 48v series-connected banks) is also a possibility.
