The limit on box fill is set in term of the number of wires entering the box -- splices don't count against it. That said, it's time to jump right into the box fill calculations. You have 9 10AWG box fill units there (1 for each hot and neutral entering, and 1 for all the grounds taken together). For each pair of marretts you count one wire(i.e 4 marretts=2 conductors, 6 marrettes=3, etc,. Each device counts as 2 wires. Divide the box ML by the wire ML and see how many your allowed to use and always round down and not up with your final answer(12.75 conductors=12 conductors)
There’s code for how many conductors you can put in per size of box. For 12 gauge wiring with 8 conductors and external clamps. It’s 9 * 2.25 (1 for ground so long as less than 4 ground otherwise # ground / 4). So 20.25 cubic inches required. If box isn’t that big you need a bigger box If that’s 14 guage then it’s 9 * 2 = 18 cubic inches.
The receptacle manufacturer should document how many wires can be put where. In general, if there are screws, you can use at most one wire per screw. For quickwire/backwire holes, you can only use one wire per hole, and further, that one wire can only be 14 gauge. Previously, 12 and 14 gauge were allowed for quickwiring, but not any more.

With most devices you can only have one wire per screw terminal, however, some breakers do support multiple wires under terminals. If the device allows multiple taps, it must be listed for the purpose. NEC 2008 110.14 Electrical Connections. (A) Terminals. The number of wires you can put in an electrical box depends on the wire size and the size of the box. A 4-inch square box that is 1 ¼-inch deep can accommodate up to eight #12 wires, nine #14 wires, or ten #16 wires. On the other hand, a 4-inch square box that is 2 ⅛-inch deep can hold more. I bought a new IKEA light fitting and its electrical box has 4 holes (2 for N and 2 for L). The instruction said to put 1 N to N and 1 L to L. And I saw many videos online doing the same thing. Mine is different. I have two cables (each has 3 N/L/E). I know that one of them is for the switch while the other is for the consumer unit.
