I am replacing a worn outlet. Upon removing faceplate & receptacle, I discovered 3 romex feeds into single box. Each has 3 wires: 1 black, 1 white, 1 copper As I understand it, usually black=hot, white=neutral & copper=ground.
Testing with a non-contact voltage tester: - one black wire is hot - one white wire is hot (both coming out of the same romex) - no other wires are hot
All grounds are combined to a pigtail with the pigtail lead going to the ground screw on the outlet.
All three white wires were connected to old outlet silver side; all 3 black wires were connected to outlet brass side.
The new outlet (just your basic, generic outlet) has screw-type connectors, not backstab (actually it looks like there could be backstab openings, but the gauge would have to be super small - existing wire will not fit): it has two brass screws for the hot leads, two silver for the neutral, one green for ground.
I've considered a few connection options:
Connect the black hot lead to the top brass screw; wirenut the other two non-hot black wires with a pigtail & connect the pigtail to the bottom brass screw. Connect the hot white wire to the top silver screw, wirenut & pigtail as with the black.
Wirenut all three black wires with a pigtail, run the pigtail to the top brass screw; repeat for white running to the top white screw.
- or -
Hot black to top brass, wirenut the other two w/pigtail to bottom brass screw; one of the NON-hot white wires to top silver, wirenut one hot & one non-hot white w/pigtail to bottom silver.
I'm hesitant 'cuz of the one white lead being hot.
Thanks in advance for advice, guidance, direction, assistance...or just the number of a good therapist...;-)
