what needs to be done to change a skutt 1027 kiln from 3 phase to singls phase

used skutt kiln not reaching temp.

updated tue 31 dec 96

RCGolly on tue 17 dec 96

I just picked up a used skutt elec. kiln and am having trouble with information technology
reaching glaze temp.
It is a model 231 which proceeded the 1027 I believe. It is rated to fire
to cone 8 but I am not able to fifty-fifty accomplish cone 6. I fired a bisq that took
12 hours to reach 06, a niggling longer than I thought it would take but
maybe I didn't step up the switching to med & loftier presently enough. When I
tried to practice the first test glaze firing to ^6 I allow it run on low for 6
hours on low, when looking in the spy pigsty, it was not fifty-fifty a low red.
Switched to med, with same results. When I went to high, the elements were
finally red and it looked like it was on its fashion. I permit information technology run on high for
12 hours and the ^four cone was not fifty-fifty starting to curve so I shut it down
after 23 hours.
Demand some assistance in troubleshooting this prob. Do the elements demand to
be replaced or the switch? The kiln is on its own 50amp breaker that has a
#8 wire running to it so I believe it is getting enough juice to information technology. I am
pretty mechanically inclined so I accept no trouble rebuilding it if need be
merely dont want to merely offset replacing all of the parts.
Thanks in advance for any direction ...

First affair I would check with a used kiln firing this slowly is whether
your curcuit is 240v. or 208v.; a lot of schools, etc. save ability past
running 208v. I got a used kiln here, wired for 240v., and on our 208v.
service information technology behaved as you describe-- firing slowly, not reaching temp. This
necessitated changing elements to those made for 208v. And then, sometimes
elements just wear out, oxidizing to where they no longer provide
sufficient oestrus.

The Skutt 231's that I've used drew 47 amps at peak. Yous need xx% more on
the breaker rating, and then a l amp breaker ain't gonna cut it. I'm surprised
that it wasn't tripping on you lot! Skutt says that you demand a 60 amp breaker
and that's what I've used. Also, #viii wire is too pocket-sized for that kind of describe.
You demand #6! Forgive me if I'thousand beingness insulting simply accept yous checked the
plate on the kiln to decide if y'all have a single phase or three phase
appliance? You might want to become some specs on the kiln and find out what
the element resistance should be and bank check them with an ohm meter. Sometimes
a visual cheque of the elements volition tell yous a lot. If they are pinkish with
lots of night grey areas, they are probably nearing burnout. If the windings
are sagging into a solid mass instead of standing alone with a lilliputian space
betwixt, they are badly anile. If the elements are old, and are causing the
boring down in reaching temp., I would alter them even if they weren't burned
out. It will amount to a big savings in elec. and your time. Besides cheque the
interbox plugs to see if they are heating during utilize. The male blades volition
be discolored and kind of burned looking if they are not making tight
contact. If the plugs await bad yous may take to change them. Make sure all
circuit connections in the kiln are TIGHT!! When yous are drawing a lot of
amps, you don't want to cause whatsoever boosted resistance with loose contacts.
Check the wall box and plug, and make sure the contact is tight at that place as
well. If your kiln is not "difficult wired" at the wall connection, bank check the
male blades on the plug for telltale burn down color. It is sometimes appropriate
to "difficult wire" kilns to eliminate arcing at the plug and minimize resistance.

Hope this helps, Craig Martell-Oregon

Virtually THE USED SKUTT KILN, IF ALL THE ELEMENTS Exercise GLOW RED WHEN You lot Accept THE
KILN ON Loftier THEY ARE Not BROKEN Merely MAY Be WORN OUT. THE OHM READINGS FOR
THE TOP OR BOTTOM ELEMENTS SHOULD Be Nigh 23.3 AND FOR THE Centre ELEMENTS
SHOULD Exist Nigh 32.6. I AM Bold YOU HAVE A 231 RATED FOR 220-240 VOLTS
AND HAVE 240 VOLTS AVAILABLE, Not 208 VOLTS (VOLTAGE IN SOME COMMERCIAL
BUILDINGS). IF YOU Take LESS THAN 220 VOLTS Bachelor Yous WILL HAVE TO GET
Appropriate ELEMENTS). I AM Besides CONCERNED THAT YOUR WIRE SIZE SHOULD Exist SIZE
vi COPPER AND YOUR BREAKER A sixty AMP FOR THIS KILN. IT SHOULD DRAW 48 AMPS ON
Loftier AND THUS A 50 AMP BREAKER IS NOT Big Plenty. Need MORE Assist I Can Be
REACHED AT 518-274-2722.

I would check the amp rating of the kiln and determine if the #8
copper wire is heavy enough (sounds a picayune light to me) for the voltage
(240 v, 480 v, etc.) that you are running and the given distance of the
kiln from your sevice entry box to carry the required load. ....Marshall

Hi:

CHANCES ARE IF THE KILN IS USED, SO ARE THE ELEMENTS. If they are about to
become that would add together many hours on to your firing. Are your sure all your
elements are ok? Maybe 1 is burned out. Have you tested them? Also, we
had a Skutt 231 and it only went to cone six.

I think that role of this explanantion is not articulate. 240v is commonly unmarried
phase power. 208v is three phase ability. I havent seen much 3 phase used in
schools. Schools are mostly located in residential areas and 3 phase
(208v) is but used in manufacturing zones. I would exist very surprised if
your local power company had routed three stage ability to your local school.
The wiring method for single phase uses only two bars in the billow box,
three phase uses three bars. You tin can tell by either opening the breaker box
(be conscientious) or examining the breakers. Unmarried phase breakers attaches to
2 confined (phases), three phase breakers adhere to 3 bars (phases). Now
the kiln itself if wired for one phase or iii will be wired differently
making information technology almost impossible to wire to the wrong power without some degree
of consious modification.

So the kiln is tiresome to fire. Check your elements with a device to measure
reistance, im sure that you will detect that the elements are just worn out
and need replacing.

You will probably get much more technical replies than mine, merely I await for
night, turn the kiln on high and turn off the lights and lookout. You tin see
which elements are out and which ones are weak.

out.

Belive it or not, thats a good respond. We accept seen this many times with a north
Your problems tin stem from a number of items. You need to take information technology one step a
Hither are some bones steps without getting into some unsafe areas

one) Visual inspection of the elements is unremarkably the beginning step.
2) Adjacent check your breaker box (if y'all have fuses you may accept diddled just ane
3) WITH THE KILN UNPLUGGED , Bank check the continuity of the elements with an
ohm meter to make sure the Kiln element loop is non broken.
4) Verify that your switches are working (Cycle them and check visually the east

These are some basic steps before you need to first earthworks. But please
be careful when checking your kiln.

Bob: I used to be an amanuensis for Venco Pug Mills and I received lots of
requests from schools for 208V 3ph. mills. In that location are indeed lots of schools
with 208V., particularly in newer construction.

I have 208v (not three phase, the two are different). My studio is located in an
office/warehous complex. 208v is often used in this type of circuitous as well
as schools. My kilns were ready for 220 when I moved in and so I just replaced
all the elements with 208 elements and they've done fine. I wrote 1 of the
kiln companies to see if that was a proper fix and they bodacious me it was. I
wouldn't take known I had 208v if my electrician, who was doing other work in
the studio before I moved in, hadn't brought it to my attending.

Bob,

The stage consequence volition simply confuse the matter. The supply voltage ie 240
VAC or 208 VAC has NOTHING to practise with the phase. We tin have three phase
ability in Whatsoever voltage we choose. Well-nigh schools and big power users Do
have three phase power and it can be either iii or four wire. The uncomplicated
solution is to measure the voltage at the kiln, check the elements for
proper choice and if all this is right check the size of the wire
guage from the mains to the kiln. If yous want a actually complete
description check the Archives.

Another quick test if an electrical kiln is working at all is to place
paper-thin matches (the kind that comes in a "book") all throughout the
heating elements and plough them on. You lot place the non incendiary ends (the
cardboard ends) in the heating elements, taking care non to bend the
elements. In brusque order- peradventure a few minutes- (if they're working) those
elements heat up enough to cause the matches to burst into flame. Bonnie
