I still wrap conductors around the terminals without cutting them in the case of multiple devices in a box. One less splice, one less wirenut to contend with. (Mine don't come loose, though).
I used to keep track of the # of wires I'd seen in boxes. The record was 32-#12 in a 4Sx1-1/2, with a blank "sort of" on it.(not installed by me of course) [Linked Image] I quit ordering 4S-Spl boxes for the crews because of their tendency to pervert them.
