Thank you to all the responses, I just measure both phases and the ammeter gives me 45 amp each one, for stay more sure about my safe I will upgrade the breakers to 60amp each phase and I will have to change #8 copper to #6 copper. Thank you!

Thank you Bill, is very useful this information, I already contact another electrician, he will rewire to copper #6 both phases. I contract a 220 service but as you know and said sometimes I get above the estimated. For now I will not turn on the kiln till I know all the wire and breakers are the better for the power of the kiln.

Both breakers are feeding by a #8 copper wire, my bad, I figured that was enough because I didn't think the kiln would go over 45 amp.

Thank you Neil, I just bought the 60 amp breakers, I will be telling you what happens.

Hello Neil, thank you for your reply, yes I was referring to the circuit electrical panel, when I turn on the kiln with all the switches on Hi-Fire, the kiln run like half of an hour before the breaker trips off. When I set all the switches in the “Ceramic” option, the kiln run like two hours before the breaker trips off. My electrical service give me 220v. Here is some photos…

Hello to all, I am new at this forum and not that good in English, but I will try to explain my problem: So I bought this old Kiln (Duncan Automatic The Pro-plus) 2 years ago, since then I use it normally but I noticed that the medium part of the kiln was not turning on while I set up to a firing, due to this, kiln was taking to long for bisque firing so I decided open the electric panel of the kiln and I found out that a cable was disconnected, I proceed to connect this cable and it solve the problem, but it brings another one, since then, all the kiln elements are turning on, but the kiln is overloading and is turning off the 50amp relay of the control panel, my kiln is 45 amp so I suppose that it should not turning off the relay. Should I bought a 60 Amp relay? THANK YOU FOR YOUR PATIENT AND YOUR HELP!
