Ground & Neutral Placement in a Panel

Rdbesq1 · Jan 22, 2022

I am pretty sure I know the answer to these questions, but because this isn’t my own panel, I wanted to double-check. I am installing a single 20amp circuit into this panel in Florida and it seems that the ground/neutral bars are full. I believe that you can only put a single neutral under any screw, but two grounds under a screw. Based on the photos below, would it be acceptable to move a ground on the left bar and double it up with another ground to free up a space for a neutral? Although this panel was neatly separated with neutrals (for the most part) on the right and grounds on the left, it is OK to mix them on both sides as long as they are not under the same screw, correct? Please point out any other issues you may see.
Thanks for any help you can provide!!!

If that is the main panel outside at the meter then you are allowed to have grounds and neutrals on the same bar. Having said that you need to keep them separate if you encounter a sub panel. You are correct stating that one wire for one screw. Be safe and turn off the power.
