I currently have an outlet that is wired to a switch. I want to turn it into only half hot so one is always powered on and the second is controlled by the switch. I understand that to accomplish this i have to break off the tab by the brass screws. Most postings talk about a white, red and black wire. I only see a white one on the neutral side of the box and the red one feeding onto the brass side. I do not see anywhere a black wire though. Any ideas? Thank you.
If you have conduit you will have to pull a black #12 or #14 copper wire from the light switch to the outlet. Pigtail this wire in the switch box to the black (feed) wire going to the switch. at the outlet connect the black wire to the screw next to the red wire. Now remove, break off, the tab by the brass screws. If you have Romex wiring, you will need to replace the /2 cable with 12/3 or 14/3 cable, black, red, white with bare ground. Wire the switch and outlet with the new wire in the same positions as above.
