Go to Skutt's web site and download the Operating Manual for your kiln (I'm
guessing you don't have one because their manuals are quite explicit on
what is needed). www.skutt.com
What you are describing sounds pretty much like my 240 volt Skutt KM-1027
(KM stands for KilnMaster--it's computer controlled). It has the same
electrical requirements as the model you have described, and so what you
would need is a 60 amp breaker, AWG 6 wire (2-conductor plus ground), and a
NEMA 6-50 receptacle and plug.
But this is TWICE as much as the 30 amps that clothes dryers require! So
your dryer outlet will not be sufficient.
If your kiln has a plug on the end of its power cable (and was previously
installed properly, i.e., with NEMA 6-50 receptacle), you will see that it
will not even fit into your dryer receptacle! The various plug/receptacle
pairs are configured differently for different voltage/amperage
combinations as a safety measure in order to prevent just what you are
considering!
Issues of electrical safety have been discussed a lot here the past few
days. Please consider NOT using a plug-in connection, but rather a
hard-wired one with a disconnect switchbox close to the kiln
location. Even Vince Pitelka, always known as being anything but absolute
in his opinions, has stated, "For any high-amperage appliance, a hardwired
connection is ALWAYS preferable. Sorry, but that is an absolute." :-)

I am interested in setting up a used kiln. It is a
Skutt electric kiln, model K, or 1027-240. Max temp
2350. Cone 10. 1 phase, 240 volt, 48 amp, 11,520
watts.
1)Can this kiln be plugged into a standard clothes
dryer outlet, or will I need to have an electrician do
some special wiring?
2)Do I need to buy some kind of ventilation system?
Thanks!

NO to the dryer outlet. Most dryers run on 30amps,
and even if the plug and breaker are for 50 amps,
the wiring inside the wall will certainly be
undersized. Undersized wiring causes fires!
If you are skilled in electrical work, you can do
it yourself. If you are not, definitely hire a pro.
That's a lot of juice to mess with if you get it
wrong.
>2)Do I need to buy some kind of ventilation system?
If the kiln will be located inside the house or
studio, YES! If outdoors or in a non-occupied shed,
then no.

Dryer circuits are typically 30 amps.
You'll need a new circuit run for a 48 amp kiln.

Yes. Check the manufacturer's recommendations on
CFM required to exhaust this kiln. You can buy a
kiln vent, but I use an ordinary exhaust fan purchased
at a home improvement store that far exceeds the
ventilation requirements of my kiln, and was much cheaper.
