Assuming that I understand box fill calculations correctly, 8 cubic inches would allow for a maximum of 4 conductors with 14 gauge wire (and only 3 for 12 gauge). If the shallow box had an outlet or a switch, that counts as 2 conductors. The hot and neutral wires would bring the total to 4. Then the ground would bring it to 5 - too much for the .Multiple ground wires are only considered to be one conductor. It must be calculated as the largest ground wire that enters the electrical box. As an example you have a two 14 gauge and one 12 gauge ground wire in the electrical box.
