New High Voltage wiring for my Skutt kiln rebuild ⚡️

- In this video I start wiring the high voltage side of the skutt kiln I'm rebuilding. First I mount the thermocouple which will be used to read the temperature for a digital controller. Then I use high temperature wire and crimp on connectors to wire the existing thermocouples. The two elements in one ring are wired in parallel like a modern Scutt 1018 kiln. The high temperature wire is then connected with a spade terminal to two relays, one for each section. Next the relays are attached to a terminal block for the 240 volts needed using short pigtails. Finally I attach the cord to the terminal block and the ground wire.

Thank You!!
You're welcome!
Also really happy to have found your video! I just bought the same kiln and now I think I will upgrade everything! So good to have you walk me through it!
Also thanks for all the purchasing links for a quick price out on the project!
that's great! Mine was obviously in sad shape and needed a lot of attention but I'm very happy with how it turned out!
Thx for this!
You bet!
I'm so happy I found your video! I am making a kiln for my mother but got a bit stuck on the electronics. It's a smaller version of your kiln. Many thanks for sharing this. Is it possible to put the wiring diagram somewhere online?
I don't have a wiring digram for what I did specifically. However I more or less followed the basic wiring of other Skutt kilns. This pdf shows how they are wired: www.skutt.com/pdf/op_manual/2009_op_manual/KM_Manual-09_WiringDiagrams.pdf Hope that helps!
@@PotterybyKent That helps a lot! You will propably hear from me if I succeeded (or if I'm stuck, but the diagrams look pretty straight-forward :) I hope my calculation for the element wire was correct. Thanks again Kent.
You're welcome!
I have an older kiln (25ampl that I'm looking to get set up (will be installing a 30 an outlet in my garage).
Similar to this kiln, mine has a 3 prong cord (2 hots and the neutral acting as ground to the body of the kiln). The local electrical inspector said I'm fine sticking with 3 prong cord.
Can you explain why your switch to a 4 prong cord is better? To my (admittedly limited) understanding, I don't see an improvement in safety since you're still using two hots and one as a ground while not utilizing the 4th wire.
Thank you for any insight.
It's been awhile so I don't remember all the details. You do only need 3 conductors - the 2 hot lines and 1 ground (not neutral!)
One reason was I wanted to bring it up to what Scutt does with their modern kilns. I also wanted to future proof in case I needed as 120v line for the controller (it turns out I didn't do this). But your electrical inspector is the expert for sure!
Nice video. Is it 10 gauge high temp wire? Can you use 10 gauge instead of making the pig tails of 2-14’s?
The high temp wire is 12 gauge (I didn't see 10 when looking) and I think this is what is commonly used.
As far as the pig tails in the junction box - I just used what I had laying around the garage. It is just normal 14 gauge and I doubled it up to make sure it could carry the load. A single wire would be simpler. A 12 gauge wire should work, but 10 could also be ok. I'm not sure what the weakest link is - my guess is the elements. Either way I didn't want the wire to be an unintentional fuse!
That's not a Skutt kiln The hinges are wrong, Skutt uses mushroom shaped porcelain insulators on their elements and they don't use screw on connectors
It is a Skutt kiln. It has a Skutt nameplate and serial number. However it is also a very old kiln, so I wouldn't be surprised if other parts had been grafted on over the years. It was obviously not in pristine condition when I got it.
