I need some help looking something up in the code but I'm not even sure if it is there. I dont know if it is code or just something someone came up with. I've heard that at a receptacle if you have just say for example a 12-2 nm romex coming in from the panel to a nm plastic box and a 12-2 nm romex leaving out of the box for the rest of the receps. that it was now code you had to make T taps on all your wires and only have one hot wire to the recep and one neutral and you can't take one white wire coming in to one screw and one white wire going out to the other screw like it has always been done. they say because if that tab were to burn out and you had t taps then the rest of the circuit would still be complete. but if it stayed the other way that everyone is use to doing and the tab burned the rest of the circuit would be open and that is what they dont want. i tried to look in the code but couldn't find it.
