Most important to proper operation of your new kiln is to make sure it has enough of the correct power to operate.
If this is done, your kiln will give
you years of satisfying service;
if not, your first firing could be
disappointing or even disastrous
for your kiln. The specification
charts on the following pages
show the recommended electrical
specifications for each kiln model.
If you are uncertain about your
existing outlets, have them checked
by an electrician. If you are
installing a new receptacle, have the
electrician follow this guide:

OperatiOn
On occasion we are asked if it is ok to use two legs of a 3 phase power supply to electrically connect a single
phase kiln. This is possible in most cases, however, you should have this connection made by a licensed electrician
who is familiar with 3 phase power supply and National and local electrical codes. It is not possible to connect a
3 phase kiln to 1 phase supply.
v
Oltage
As you can see from the chart, most Skutt models
are available in either 208 or 240 volt versions. The
exception is Model KM714 which is universal, and will
fire with a 240V or 208V power supply.
While 120/240V supply is still by far the most common
supply in residential communities, 120/208V supply is
increasingly encountered in commercial areas, schools
and occasionally newly-built communities.
If you find that the designated voltage of your kiln (found
on the serial plate) does not match your supply, do not
connect it. Doing so could damage the kiln and possibly
overheat wiring in your electrical supply. Contact the
factory for instructions on how to safely convert your
particular model.
714 Wiring
i
MpOrtant
:
The wall outlets for Model KM714 must be
powered by 3-wire 120/240-208V solid neutral supply. No. 10 wire is required for runs under 50 feet. 30 Amp
fuses or circuit breakers are recommended. The U-shaped fourth blade of the 4W30 Amp grounding plug is for the
solid green grounding wire. The blade opposite this U-shaped one takes the solid white neutral wire.
