So, this smart part with the solid state circuitry is inside the cord itself?
I can run my boat entirely off one 30A cord ( as long as I don't go over 30A) or two 30A cords to a 50A "Y".
My boat has worked with and without the smart cords.
How did my model year 1986 work without the smart cords?
There are two different kinds of 30-to-50 or 50-to-30 Y cords.
One (The "Smart" or "Reverse" Y) takes two 30A supplies from shore, and converts those into single 50A supply. Given certain conditions (30A circuits are in opposite phase, ours says it needs a minimum of 208V to work; see the 167RYN in the Marinco link, and note the big honkin' box at the junction).
The other is an adapter that starts with a single 50A shore source, and splits that into two independent 30A supplies. (See MARINCO EEL Y Adapter, 30A F-50A/250 M, Power Cord Adapter at West Marine)
For your description, sounds like you've encountered the latter? I guess this because you can run your boat on two separate 30A cords, assuming your shore supply is two 30A circuits. (Yes?) I too could run select stuff on both 30A circuits on a previous boat using only one 30A shorepower cord... as long as I didn't exceed 30A.)
If the latter is correct in your case, you would have no use for the Smart/Reverse Y version, because you don't need a 50A supply to run stuff in the boat. (And that can be a good thing; they're expensive.)
