A colleague has pointed out that the NEMA 20 A plug is indeed
accepted by some North American certification houses as meeting
the Pluggable Type B definition.
The thinking is twofold: 1) the 20 A receptacle is ALWAYS a
grounding type, and 2) the 20 A plug is not subject to the same
abuse as the 15 A plug.
Best regards,
Rich
