I'd call an electrician. I'd be afraid I'd damage the oven trying to do it myself.

definitely call an electrician. If you connect the wires out of sequence it will not work. I sincerely hope you are installing this oven in a commercial building with 3 phase coming in or you are going to shell out some bucks to have 3 phase brought in to your building. 3 phase is usually used for high power motors like on radar or hydraulic pumps. Does it say it is three phase or are you just counting wires? Sorry have to ask. I was a generator mechanic in the Army!

If it is a 3-phase system, the building has to be wired for 3-phase. What happened to me is I had a piece of equipment that was 3-phase and there was no 3-phase wiring in the entire strip mall .... a new piece of single phase wiring equipment had to be spec'd in. (It was the heat booster on my comm'l dishwasher).

Call an electrician. Unless you do electrical work for a living, I wouldn't touch it myself.

When you say the building isn't ready ... are you building a new building? Doing a build-out on an existing building? I dont' confess to knowing much about wiring but I would think to re-wire an entire building for 3-phase would be a major expense.

Let us know what the electrician says. I'd like to know how this works.

Your next call should be to the local power company and see just what they need to put in. I'm suspecting a transformer and the panels the electrician mentioned. It's probably not going to be cheap either. The panel is similar to the "breaker box" in your home except it is set up for 3 phase. It requires larger wiring and breakers to handle the power load. Good luck

PLEASE TELL ME WHAT COLOR ARE THE WIRES? IF THE BACK OF THE OVEN IS ACCESSABLE READ THE LABEL AND WRITE IT DOWN FOR ME. I AM ALSO AND ELEC SO I MAY BE ABLE TO HELP YOU. IS THIS NEW OR USED EQUIPMENT? IF USED WHERE DID YOU GET IT FROM AND HOW OLD IS IT. IF YOU GIVE ME SOME OF THE SPECS MAYBE I CAN LOOK UP THE EQUIP AND TELL YOU HOW IT SHOULD BE WIRED SO YOU DON'T GET TAKEN BY THE ELEC.

Sorry about the cap letters, Cap lock is always on for me. I would definetly go with 3 Phase wiring. Also get the largest panel you can afford. Will you own this building or are you renting it. This will determine how much money you want to put into it. Will the elec charge you for the panel plus breakers or will he give you a panel plus x amount of breakers and charge you for any additional. You need to get a detailed break down of everything the elec will be charging you for on paper from him. The cost of copper is going up. They will also charge you per outlet and fixture. If you have any questions just ask. I may be in a different state but wiring is wiring. The local codes may be different thats about all.

Your first call should be to your local electric utility company and see if three phase is available in your neighborhood. If it is not, it could be very expensive to get it built in there, or it is possible that it would not even be a feasible option. Some utilities have a minimum KW requirement before they will provide three phase service. Your next call should be your local inspecting authority, i.e. city or county electrical and building inspector. From the nameplate on your oven, it appears that you will need 120/208 WYE three phase service. What you must understand is if you have 120/208 three phase wye service to your building, you can not have the normal 120/240 single phase. Therefore, if you have equipment i.e. a single phase air conditioner, that requires 240 volt single phase, you can not get that from a 120/208 three phase wye service. You need to compile a list of all of your equipment and have a local electrician meet with you and the power company. A possible solution to this is 120/240 four wire three phase service. Ask your electrician and local power company about this voltage -- not all power companies will provide this voltage. If you exercise that option, it would require a dry type transformer at your expense inside the building to convert 120/240 four wire to 120/208 wye. THAT WILL BE EXPENSIVE.
