Service Panel

I have a 200 amp Service Panel that has only one neutral/ground bar. I am going to install double oven in a redesigned kitchen. My question is: Can i only run a 3 wire to the oven, or can i run a 4 wire and tie both the neutral and ground wire to the bar?

If the oven is a 120/240v circuit you MUST run a 4-wire circuit to it. This is code for new circuits.
If it is straight 240v then 3-wire is all that's needed.

A main panel's neutral bar is bonded to the panel box and it is used for both grounds and neutrals. This is basically the ONLY time the grounds and neutral are attached to the same place.

As Speedy Petey said, in the main service panel -- and only in the main service panel -- you can connect both a neutral and ground to the neutral bar, just make sure they go to different terminals on the bar. While only one neutral may be inserted per bar terminal you may be able to insert two grounds if you need room for ground wires (this will depend on the gauge of the grounds and your local code).
