To push those kinds of AMPS cords must be kept short or have massive diameters.
Current capacity of the cord can be solved with diameter and/or materials.

That's off-the-shelf technology, heavy industry does it all the time.

The connector might have to be special. Large ships don't "plug in" to shore power, they actually hard-wire the shore power wires to the ship's electrical bus. It only takes a few minutes, but it's probably a little too technical for line use. And you need to be absolutely certain the breakers are off before you bolt a wire to a high-voltage bus

Probably just need a connector with a mechanical latch-in feature and good seals. As opposed to the current 115VAC 400Hz aircraft push-in plugs, which has the same arcing potential as residential house current.
