I’m hoping to get some troubleshooting advise for my kiln. It’s an old manual kiln but new to me, I’ve only completed 1 bisque fire (cone 04) and 1 glaze fire (around cone 6) since I’ve had it. The witness cones on my top and middle shelf look consistent, though I did find it odd that the cone 6 and 7 are bent nearly identical, and none of the cones on my bottom shelf bent at all. It had to be at least near cone 5 because the glaze came out looking normal on all my pieces. Visually I think the coils look ok (see picture). I don’t have a multi-meter yet but I noticed that there is a decent sized gap between my bottom ring and the floor of the kiln, and it looks like some of the bricks on the floor could use sealed in between. I just bought kiln cement and I plan to use that on the bottom bricks, would it be ok to use the cement for the gap in between the bottom ring and the floor as well? The gap is there even when the kiln is cool, so it’s not just from heat expansion. Could the gap be my issue or is it more likely an element problem? Thanks

@Linchimb Was a kink in the belt your issue and did you get it worked out? I bought the exact same wheel about a month ago and it has the same thumping noise. I’ve used it several times since buying it but maybe not enough.

Thank you both for your help! My voltage supply is 240v. @Hulk thank you for the source on the cable. That is definitely cheaper than the 4/3 and local prices. I’m an amateur in this field, do you know why the 6/3 cable that you recommended is rated at 75amps while the 6/3 I’ve found locally is only rated up to 55? I’m just curious what the difference might be since they’re both the same size.

Thanks for your response/info. I’m not sure why the photos didn’t work on the original post, but hopefully they show here. So I should be ok with the 4/3 cable with a 60amp breaker?

I just bought my first kiln and I’m hoping for advice on how to proceed with the wiring. I’ve done some research online and consulted an electrician, but the answers they are giving me don’t all match up. kiln specs are: 43.98 amps - 10,555 watts - 240 volt - model J230 My kiln is going in an outbuilding separate from my house and it will require about 55-60 feet of cable between my breaker box and the kiln. My electrician told me to use 6/3 copper cable with a 50amp breaker. But from the information I’ve read online it sounds like that may not be enough because of the distance of the wire. Plus the 50 amp breaker doesn’t fall in line with the 125% range for amperage, and 6/3 wire is only rated up to 55amps. Am I over complicating this? Would the 6/3 wire be ok or do I need to go up to 4 gauge wire?
