I have a problem. I need to install three breakers, I have four free spaces left for the white wires, but only two free spaces for the ground wires. Is it allowed, under the code, to put two grounds into one space? I do not want to install a subpanel. By spaces I mean the screwed holes on a rail where the wires are connected. I am not sure whether I can install more of those connection modules, this panel seems closed on one end. I do have enough spaces to put at least 6 more breakers.
I have also noticed that some of the spaces have more than one wire in them, but they all belong to the same cable. I am not sure how the builders arrived at this imbalance, since for every white there should be one ground and the number of spaces for whites and grounds is the same.
