I am rebuilding an old Duncan DK820-2 kiln for testing glazes. I need to replace the elements because of age and plan wind my own. I have ordered from Euclid 14 gauge Kenthal A1. Euclid says that the ohm reading should be 4.5 ohm for each element. The problem here is that this is close to the OLD manual that says it should be 4.6 but the new elements from Paragon (the current owner of Duncan) are 5. I did the math and according to the formulations it should be 5 for the specs on the boiler plate of the kiln. Paragon sells 220V elements at 4.6 ohm, 240V at 5 ohm, my kiln is 240V. Is Euclid covering for a under powered kiln by trying to push more amps through the kiln? My concern is if I go with Euclid's recommendation of 4.5 ohms will the elements burn out much quicker? Will I have a harder time reaching the top temps for the kiln if I go with the 5 ohm recommendation from Euclid? Who out there has had experience with this kiln and what has your experience been with the element replacement and performance?
