Why? It allows you to use both 15A and 20A appliances.
Because it allows both sorts of appliances to be plugged in? Note
that it would be against code to install this outlet on a 15A circuit.
You haven't looked hard enough. They aren't all that common because
most appliances draw less than 15A, so 15A cords are plenty. However,
they do exist. Many air conditioners have 20A plugs. The plugs are
also available at the usual places.
A NEMA 5-15 plug and cord set applied to a 20-ampere branch circuit could be
exposed to approximately 78% more real power than it's Listed rating. The
conductors are essentially resistors ... and in a resistive circuit, power
increases as the square of current. Subsequently (20 amperes)^2 is much greater
than (15-amperes)^2. As a result, the power cord will overheat and possibly
burn up. It's really quite easy to conduct this experiment with an extension
cord ... but have a fire extinguisher present ... because loading up a "Listed"
extension cord beyond it's listing or labeling requirements will most probably
result in a fire/electrical hazard ... and since it's listing efforts (Testing
for Public Safety) did not include exposing the extension cord to possible
overloading (up to 20-amperes).

Wrong. What is the rating of 18ga wire? ...or are you saying that
there are no appliances with 18ga wire? I suppose it's illegal to plug
a lamp into a NEMA 5-15 outlet on a 20A circuit? You'd probably shit
if you caught me plugging a lamp into a NEMA 5-20 outlet! <sheesh>
Completely irrelevant. The circuit breaker is *NOT* there to protect
your cord, or appliance. Good grief! LEARN SOMETHING!
Now there's a response that clarifies absolutely NOTHING! KRW ... Review
Articles 100, 200, 300, and 400 of the latest NEC for clarification of the
purpose of circuit protection. I also encourage you to contact U.L. for
clarification of requirements of Listed and Labelled equipment.
It appears you have a denial problem ... and either refuse to debate the issue
... or just can't. When you grow up, I'll explain it again to you ... but with
Power: there is real, total, and imaginary power. Goggle it for yourself and
perhaps you'll be enlightened.
May the force be with you.

Speaking of explaining things, why haven't you explained why the same
alleged safety problem related to breaker sizing with 20 amp circuits
doesn't exist when we all plug floor lamps, radios, clocks, etc that
draw an amp into 15 amp receptacles.
just like a fundie...blame everyone else for their failures. your
inability to debate is demonstrated on almost all of your posts, unless
in your feeble mind calling someone a PLCCF or Liberal or Lefty
qualifies as debate
krwless goes to the hospital with her mother to visit her Grandpa. When
they get to the hospital, she runs ahead of her mother and bursts into
her Grandpa's room.
"Grandpa, Grandpa," she says excitedly, "as soon as my mom comes into
the room, make a noise like a frog!"
"What?" said her Grandpa.
"Make a noise like a frog because mom said as soon as you croak, we're
all going to Disney World!"

The idiot liar takes a month to come up with some lame lie that no one
will ever read. Malformed is such a dumbass. But that goes without
saying because he is a lefty snot-nosed kid living under mommy's
