A pretty common practice where I live is to twist the grounds that pass thru a jbox say for a receptacle or 2 gang box with two switches. I see the grounds twisted together for say 1.5 inches or so, tight twists, then cut off the grounds and leave one or two long to connect to the switches or the receptacle. Is that acceptable by code?
As iwire and others noted --- this is definitely not kosher.
To use this approach properly, use a green wire nut to basically "cap" those cut off grounds:
Personally, I find this method ungainly -- plus the greenies are more expensive than regular wire nuts.
I'll use a pigtail if necessary, but prefer to just leave one ground wire long (12" or so), wrap it around the ground screw of the box and/or device and then terminate it with the rest of the grounds using a std wire nut.
