Hi,

Is your new Hob gas or electric?

Being new, it should have come with some kind of manual or install instructions...are they missing?

Has any body measured the incomming power lines with a volt meter...across black to red...red to yellow, and black to yellow. Post these and Mr Wgoodrich should be able to help :)

Jeff that Mr. part never did fit me just being a country boy. Wg or just Warren is fine. YOu make me sound like somebody important wiht that Mr. bit. Ha Ha.

I have a question then a concern.

First WHAT IS A HOB ? Don't mean to sound dumb but you got me on that term.

IF IN THE USA;

My concern is the rules of electric demands that green or bare or green with a strip must be used as a noncurrent carrying equipment grounding conductor only.

White or gray must be used as a current carrying nuetral if 220 volt or current carrying return path being a grounded leg if 120 volt.

All other colors in the spectrum is considered as hot wires.

You state that your existing wiring is black red and green with yellow stripe being two hots and a noncurrent carrying equipment grounidng conductor.

Your new appliance has a red white and blue being two hots and an current carrying neutral but no equipment grounding conductor.

If this appliance is a USA made appliance then look for a green grounding screw mounted to the metal casing of your appliance. This will be your fourth wire being where the equipment grounding is supposed to be connected.

My major concern here is that your old appliance did not use 120 volt components due to the missing white wire on the old equipment, thus not needing a white neutral wire in your branch circuit wiring.

Your new appliance is showing that it has 120 volt component because of the presence of your white wire on the appliance.

Look at your installation instructions and it should confirm what I am saying.

Then take a voltage test on the existing branch circuit between the black and red wires, you should read 220 volts. Look at the name plate on the mysterious HOB and confirm it says 220 volt rated / 120 volt rated.

Let us know what you find.

Be careful. That green wire is not supposed to carry the current of the white neutral wire. I am suspecting you will need to install a new four wire branch circuit with a neutral wire being black red, white and bare or green.

Right now just don't know what a HOB is.

Hope this helps

Thanks Jeff, that brings up a concern we haven't touched on. Europe, Canada, and USA all have different rules that would apply to this installation. Need to know what country this applaince came from and what country it is being installed in.
