Ponder this:
While my boat is up on hard, I want to plug it into shore power, only 20amp receptacles, but lots of them.
No need for lectures on the load here, I'm not trying to draw a lot of electricity, I know the loads, it's about testing the systems, keeping the small battery chargers running, and being able to use power tools around the boat without tripping over extension cords everywhere.
Boat system: 50amp 250V, divides the 2 120v legs into front and rear half of boat roughly.
You might ask: Is there a 240v appliance on the boat that would be affected by this plan I'm about to describe? Not that I'm aware of, and if there is, it's the oven and I'm not planning on using it (not living on the boat, working on it).
So why can't I find a Reverse Y that allows 2 15-20amp 120v legs to power the two 120v legs in the boat each on a different line. Yes, they'll be in the same phase, and yes any 240v appliance will NOT work, but I wouldn't have to have drag extension cords and long leads around to test outlets run tools, etc.
I bought a Marinco Reverse Y adapter, and it tests for split phase 240v and will not run otherwise. Argh!
Help me understand. Maybe there is a danger I'm not aware of with single vs split, but if anything I'd consider split phase 240v to be more dangerous anyways.
Maybe 240v appliances would be smoked if this was supported...?
I can't figure out how to accomplish this without wiring it up myself, and while I'm capable, if it's not done already, there's probably a good reason for it I'm missing.
So what am I missing?
