The grounded white conductors "neutrals" can only terminate with one conductor per terminal and the EGC's may take two or more of the same size under a terminal when the instruction so state that fact per 110.3(B). If that picture is a sub panel then the problems get worse and the reports expanded, see 408.40 and 41 in the NEC. Let me know if you need a copy. PS: This forum is a breath of fresh air!
