Rewiring 3 Phase Kiln To A 1 Phase?

Piece of cake, especially for an electrician. The big difference is that the 3 phase model uses an external contact switch, and the single phase doesn't. What that means is that the kiln sitter is not actually connected to the power inside the kiln. It's connected to a cord than runs outside the kiln, to a contact switch on the wall that's connected to the kiln outlet. When you push the power button on the sitter, it turns on the contact switch, which send power to the outlet, which goes to the kiln. The 3 phase model has the leads in the power cord going directly to the 3 sections of the kiln. It does not connect to the sitter block. You'll need to get a new power cord, and the two hot leads will connect to the top of the sitter block. The feeds to the kiln sections will come off the bottom of the sitter block. Contact Skutt to get a wiring diagram for the single phase setup. You may also need to get a new set of internal wires, as the old ones may not be large enough since the 3 phase setup runs on lower amperage. If it has the old interbox plugs, I would upgrade that as well. Those plugs are a major weak point in the system.
