one more for the STB, and you've exceeded the safe rating of the
receptacle.

Only if you're plugging everything into the same receptacle.

That's why I said the 'safe rating of the receptacle'.

Consider a plug strip used with a home theater setup.



Add an electric blanket or waterbed heater and you've
blown the circuit. Then
add a window AC unit, or plug in the rug steamer...


Though to be fair - are you really going to be running all of those at the
same time?

How many homeowners know what circuits each receptacle is part of? I assume
the worst case, most uninformed homeowner, who does plug the iron into the
same branch circuit his/her A/C window unit is using.

Given that a (not perhaps typical) home theater setup can easily
draw 12A+, I think 20A circuit should be used for all living space receptacles.
