Code Question

I'm afraid I'm not near a NEC code book at the moment and I need to know a code number. It is the rule governing the running of power from two different transformers through the same raceway. Termination in the same box. Anyone know the code?

updating outlets to gfi in a 1930's house with old nm wiring

G

gklg723 on Oct 22, 2003

I own a 1937 house with old NM brown jacketed cable (2 wire one with a black stripe the other solid). I am in the process of updating my outlets with GFI's and 3 prong outlets downstream of the GFI with all the required marking for this installation without a ground required by code. I'm in the process of trying to find the line/load so I can install the GFI outlet properly and over this past weekend I have uncovered the following conditions. In a few locations i have found the end of the run (2 wires coming in the box) but in the middle of the run I have found 6 wires and on one outlet 9. (From my research I was expecting to find only 4 wires.) Of the 6 coming into the box 2 have the black stripe and are pigtailed together, 2 are solid and are pigtailed together, another 2 are solid and pigtailed together and on some of the older outlets there is a connector wire connecting 2 of the terminals with the solid wires (on the same side of the outlet). I am confident there is no ground in this system. What is that 3rd pair of wiring? (I think one pair is hot, the other neutral and the 3rd??? I don't know.) In order to find the line side for the GFI i need to break apart the existing wiring with the pigtails. How do I do this without damaging the existing wiring? (It is taped together and fairly stiff) Once i determine the line side with my voltage tester i assume i can pigtail the load wires together and connect them to the outlet. What is the best way to pigtail this old wiring? Plastic wire connectors or electrical tape? Can anyone recommend any books for this type of wiring and repair? I have Rex Cauldwell's book "Wiring a House" but it deals mostly with newer houses and not older houses. I hope someone can help me out there or is it time to call in a professional electrician? Thanks for your time.
