I have had to do this at times but it is not strictly allowed by codes and not at all recommended.
It's an active fire hazard. The cables aren't rated (= built) for the power draw.
That's a problem in the other direction, but plugging a 20A device into a 30A feed shouldn't be a hazard at all.
Unless the device you are plugging in does not have its own breaker. If it doesn't, then your 20A cord could catch on fire before the 30A breaker trips. Not incredibly likely, but possible. -Randy
