I put in some new boxes in my basement and made sure I met code with having enough insulation going into the box, but I see now that I should have maybe left more free wire in the box. I found mention of a six in rule that's sated below. Anyone know if it's code? I'm pretty sure I have seen many boxes with less than six inches of free wire inside.
Cables Entering the Receptacle Box
When electrical cables route from box to box, you must leave at least 6" of free conductor wiring in the junction box for connection purposes. In article 300.14, this technique is explained. If wires are too short, it's much too hard to make a connection and in the event that you need to trim off a bit of wire to rewire a switch or outlet, you'll need a few extra inches of usable wire.
