Scott,
I checked my copy of Richter and Schwan's Practical Electrical Wiring and
they have a table of allowable distances from your service to the device
based upon the amperage and wire size. Contact me off line with the amperage
and the distance and I will look it up in the table and give you the info.
It sounds like a low voltage condition.
Regards,

Last year I redid the elements to 208 Volts which is what our school runs.
Then I rewired the wiring with new 12 guage high temp wire and connectors,
new switches and relays, and a new dedicated 100 amp line. It starts out
pretty quick and hits 2000 degrees in about 10-12 hours. The last part

think of what else to try at this point. Any ideas?

Sounds like everything is new and should work but somethings wrong when you turn it on high. Bad switch, bad element.

Michael,
I'll throw this up to the group also and see if it "sparks" a memory. This
summer we rewired the kiln to a dedicated line direct from the transformer
building which is about 30 feet as the crow flies and probably a few more allowing
for twists and turns. A professional electrical outfit put in the new panel with
one 100 amp breaker and direct wired to the kiln with no plugs. It should be
drawing in the area of 65 amps. We have talked to the Olympic Kiln people who are
helpful (love the Georgia accent) and have tried everything they suggested. The
connectors that go between the elements and the connecting wires are new and
tight. The kiln for glaze loads is started on high andgets going pretty quick
according to the pyrometer. It's just that last 200 degrees which is slow.

Scott,
I have a question about your kiln setup - do you have mechanical switches (i.e. "it
starts on high . . ) or are you using a digital controller? If switches are they on
hard (no clicking on & off)? Same question if you have a controller - are your relay
locked fully on or are they switching on and off?

Scott,
The reason of asking was quite simple. Whether manual switches or controller controlled
relays, the elements with in the kiln can't produce their max heat unless they are fully
on. So when I read you were experiencing slow ramp rates during the last part of your
firing, I wondered if cycling switches or relays were the source of the problem. As stated
in an earlier post, we are testing a new digital controller and experiencing slow firing
rates too - which I'll address in a separate message.
Sorry we don't have any other advice or solutions for your problem!
