The step down transformer idea might be reasonable if this is a trickle charger. Get a "travel adapter" type that will give you enough power. If this is a real charger, the transformer might be prohibitively expensive. As has been mentioned here, you really need to see what you have there first. You might have a white wire in there. One thing the internet is good for is you have access to foreign things like battery chargers that will work on 230-240v.

It has to be treated as if it was a subpanel. (not next to the main panel)

For around $500 you can have a transformer that properly steps the voltage down. This one is 1kva, which is plenty for a charger. You would also need to provide proper fusing for primary and secondary sides. Probably all in for 750-800. By the time you do all this, you would probably be just as good to extend the nearby 110v circuit up your dock to the lift location. Should be able to get that line ran for between $600-1,000.

I don't know half of what the legit electrics have posted here. But residential is split phase. Transformer is tapped in such a way that the 2 hots are 180 degrees out of JUST ONE phase. Hence the 220 or 240. Two smaller waves in sync make a bigger wave. Two legs of 3 phase reads 208 because the waves are out of sync and partially cancel each other a little. For a bunch dudes that talk about, ride on, watch... waves.... it's kind of ironic.

The shit show is gone but boy did I have a hell of a time keeping the neighbors little bastards away from the water heater. Every time I went out there those kids were messing with my setup.

1kVA is serious overkill unless you're trying to recharge your deep cycle trolling battery bank

A little more exposed wiring with improper grounds and that problem solves itself!!

no diodes to prevent back flow so why does it matter where neutral and ground connect ?

Not sure why diodes would matter or not?

The reason you don't tie them together is because the neutral is INTENDED to carry current, and the ground is not.

If you tie them together and they are the same wire size, then both wires will carry half the current from the sub-panel back to the main panel. That could introduce some serious safety issues.

I am quite sure I am right. I was in my elementary school spelling bee in 1963.

Maybe you should go back.
