Would like clarification


Looking to purchase some new outlets, I've heard folks say that you can't use 15 Amp power cables in 20 Amp outlets,
it looks like the 20 Amp outlets I commonly see will accept a standard 15 Amp power cable plug. Why not?

20 amp outlets accept 15 or 20 amp cords.  20 amp IEC (component end) is different than 15 amp IEC and are not interchangeable. 
The rule is if they fit together they can be used together. Remember that one simple rule it works with everything.
