Eaton Panel - Which is Neutral/Ground?

Hello,

I'm adding a 30A Dual Breaker for my Generator Interlock Kit. I'm confused on which bar is Neutral/Ground in my panel. They both look like they are exactly the same thing? Appears that both neutral/ground wires are terminated on the same bar, on both sides.

I'm assuming when I terminate the neutral/ground for this 30A breaker than I can just use this bar for both?

You can use either bar because the neutral is bonded to the ground in the main service panel where the first disconnect is located.

In a main panel like this one, they are the same.

If this was a subpanel, there would be 4 wires feeding it and the copper bonding strap in the middle of the right bar that connects the bar to the metal box would be removed. A separate ground bar would be screwed to the box using some of the tapped screw holes elsewhere in the box.

Forgot to add, even though you use the same bars for ground & neutral neutral wires still must be one-per-screw on the bar. Grounds can usually be doubled or tripled per screw depending on the panel label.
