You may be thinking of the requirement that if a 20 amp circuit only

single receptacle then it must be a 20 amp receptacle. If there's more
than one then 15 amp receptacles are OK. The packaging for 15 amp units
usually says something like 15 amp plug, 20 amp feed through.


In case it isn't obvious, a duplex receptacle is not a single
receptacle. A 15 amp duplex receptacle can be installed as the only
device on a 20 amp circuit.
