This commercial oven has a wiring of three colors: Red, white and black. Is this single phase or three phase? How do i wire it if i have a power supply of 240VAC at the power point?

 

What does the nameplate on the oven say?

Most likely -- assuming you are in the U.S. -- it is intended for 240VAC split-phase in which the red and black are the line connections and white is the neutral.

But check the nameplate.

 

The brand is WOLF but it has no model number written on it. Although, i had done some research and it looks like a DF366 model. I am not in the U.S but this was bought from U.S. Can you Specify on the wiring of the Oven?

Okay thanks! Now our usual color coding here is Red/Brown for Active, Black/Blue for Neutral and Green/yellow for Grounding. Which colors go together?

 

Is it similar to this?

This sounds like single phase (not split phase). Which country are you in?

In the U.S. the normal color coding for 120VAC appliances is black for line, white for neutral, green (or bare) for earth ground. For 240VAC the second line is normally red.

If you only have 240VAC, the you may have a problem with the controls for the range because they may be intended to run between one line and the neutral.
