2 hots in light box + fixture screw question
I replaced a standard procelin light fixture in my basement with a similar replacement. It and a second light are controled by 4 way switches (controlled at 3 locations).
Inside the box there was 3-12g wires. (1 neutral, 1 black hot, 1 red hot). The red hot was connected to the light fixture and the black was heavily wrapped in electrical tape and a red wire nut.
I hooked up the new fixture like the old and removed the electrical tape and put on a yellow wirenut and did not wrap with electrical tape. I mention this because of one of my following questions.
1. In that configuration, why is there a second hot wire in a light fixture box??
2. I was concerned that the second hot in box could at sometime come in contact with the exposed screws of the fixture. I figured that why it was wrapped heavy in tape.
Its placed at the top of the box and dont see it coming in contact with screws but it could occur I suppos and I didnt otherwise want to gum it up with electrical tape..... Should I be concerned with this scenario?
