Main load center grounding question.

There are just enough spaces on the right side for what I currently need without even adding more circuits.

There are several spots on the right bus that are for larger cables and a 12-14 ga wire won't fit tightly in them.

I have several circuits that were combined due to the limitations of the old panel. I am separating them as well.

For example, the kitchen counter outlets are wired on the same circuit as the well pump. I am putting the pump on its own circuit.

I would double/triple check that. Every well pump I have run across has been 240V and that wouldn't do well for kitchen counter recepts.

Ground bars come in many different lengths. You can buy one that fits above the main breaker. This would remove the need to wire nut all those grounds. Screw it to the box and it's considered compliant, but I'm a little OCD so I'd run a little scrap wire to the neutral buss. The label on the door will have listed a maximum number of circuits. If you put in tandem breakers, you have to stop at the circuit maximum. If you're required to put in Arc Fault breakers, they each require a full space.

They are indeed wired together. The well pump was "tapped" into the kitchen line via a JB. I will be removing the well pump from the JB and running a new line for it directly to the panel.

The pump can do 240 or 120 and is currently wired for 120. Since this is just for irrigation, I will likely leave it for 120.
