"nema 1-20P ?" I had a look at a NEMA configuration chart for a 120V 20A connector & I could find a 5-20P but no such animal as a 1-20P exists...what connector would one use for a double insulated appliance that drew > 1875 watts?

IMO use a 5-20, even for the sake of using the ground pin for polarity.

Strangely, there is a NEMA-standard DC wiring-device series… NEMA “FSL-1” rated 28VDC 30A.

You're getting rather close to British ideas there, where a BS1363 plug has the ground pin whether it's needed or not. Some of the latest molded-on plug sets actually have a plastic earth pin.
