I recently ordered this kiln: http://www.bigceramicstore.com/cress-bt711h-kiln.html, thinking I could upgrade the breaker from 15 to 20 amp (outside GFCI outlet on a covered porch), only to find out the wiring to the outlet is 14 gauge and would need to be 12 to handle 20 amps. They recommend 20 amps for this kiln but it doesn't say it's required. I also have a Paragon Fusion 7 Glass kiln and have used this outlet going to max temp. (1700 deg.) for pot melts many times with no problems. I usually fire my glass overnight with nothing else running and would do the same with ceramics in the Cress. Am I going to have a problem tripping the 15 amp breaker? The cost of upgrading the wiring to handle a 20 amp breaker has me worried. Thanks
Hi, Had a bit of a scare on the weekend. I have a Paragon Model LT-3K kiln, and have run it for three years without much issue. I was firing cone 06 on the weekend and was moving the top temperature dial from 1 to 2 and I saw a flash on the top side of the kiln while adjusting the knob. I looked into the kiln as the lid was notched open at this point and the top element was on. I called my local Paragon dealer and they asked if I had vacuumed the coil channels recently, and I replied no. She said sometimes if a bit of glaze gets in there it can create a small arc. She said if the element is still working it should be ok. As the kiln was working fine, and I could not get the flash to occur again (I tried to adjust the temp using the knob up and down) I continued on with the fire. Fast-forward 5 hours, the lid is closed, and plugs are in. The kiln is not at Max heat yet but pretty close. As I move the top knob to 5.5 on the dial setting a large flash occurs, very bright, with an audible pop. The flash (what I think is an arc) then knocks the power to the whole house out. The kiln is in the garage and I have a dedicated 30A breaker for it. I went to the basement and tripped the breaker restoring power. I went back to the garage, the kiln didnâ€™t reach temp so the kiln sitter had not tripped, the power light however was not on. I unplugged the kiln, and let it cool. Yesterday I unloaded it and there was nothing touching the walls or coils in the kiln. I donâ€™t feel that I have glaze in any of the coil channels. I am at a bit of a loss to what may have happened. Paragon is closed today as is my local dealer. I plan to have an electrician look at it, but would like to give some direction to him. Any thoughts on what may have happened? Thanks ~Mal
I live in Los Angeles, I've just started renting my very own studio in a commercial space, and I need to find an electrician to do some upgrades to include installation of a new electric kiln (either Skutt or L&L, my first kiln, and I've never even fired a kiln yet!!) I've already heard and read more about the myriad nightmares that can come from a bad electrical job than is good for my mental health. Even done by a licensed electrician, when they don't understand the extreme requirements of a kiln! (has anyone seen the instagram pics of @lyonclay's kiln meltdown?) I plan to avoid that from the start if I possibly can Whoever does this work will be getting a strict lecture from me about taking no shortcuts and following the manufacturer's specs and installation instructions TO. THE. LETTER. but it will be more of a comfort to know that the one I hire will have done this at least once beforeâ€”successfully! Thank you for any and all recommendations and advice!
I fired (04) my kiln last night (Skutt KS Manual) and everything went fine. It did cut off at the appropriate time, BUT the sitter switch did not fall. (Which is weird.) The timer still had 3 hours left and the breaker was not blown. When I tried to test and see if the kiln could be turned back on this morning, it won't respond at all. No lights, no noise, nothing. I just put new elements in the kiln in the fall. I don't know a lot about the electrical or "how it works" of kilns, so anyone with ideas or advice will be a great help and much appreciated. Thank You!
