Arnold/Clayart:
I am replacing some wiring between the elements and the control relays
on one of our kilns. Realistically what is the minimum temperature
rating that this wire should have? the old wire is fiberglass
jacketed with some unknown material inside. best I could tell it is
rated for 200C. The only wire I can find available with a fiberglass
jacket is rated much higher and costs twice as much... Trying to save
the good people here some money, but don't want to have things burn
up. Do I go with the fiberglass jacketed stuff just because that was
what was there, or do I go with silicone/PTFE insulated wire rated at
200C or higher and call it good?
thanks,
jon

Jon,
The wire that we use is SRML12 that is rated for 200C. It is an insulated
silicone wire. In the old days of sitter kilns, 105C. wire would work.
Today's computer controlled kilns, use the good stuff. The lead wire is no=
t
a place that I would want a cheaper or uninsulated wire.

Thanks for the reply. I wasn't planning on using anything less
temperature wise than wire rated for 200C or more, just wondering if
it is worth the extra money for the fiberglass coated stuff that costs
twice as much and brings the temperature rating up to 250C and then on
to 400C or higher.
