NEMA 6-15P versus 6-20P plugs

Does the equipment documentation specify NEMA 6-15P or 6-20P?

Computer-generated illustration, not a photograph. — P273 · ConnectorNEMA 6-15P plug

How they differ

NEMA 6-15P plug Confirm NEMA 6-15P from permanent markings or exact documentation before selecting any mating equipment.
NEMA 6-20P plug Verify NEMA 6-20P from markings or product documentation before reasoning about the circuit or mating receptacle.

Then askDoes the equipment documentation specify NEMA 6-15P or 6-20P?
