I just removed on older lighting fixutre from my dinning room. There two groups of wires to this fixture. I think one group of black, white, bare wires appears to come from a wall switch. The second appears to be going away from the fixture. My problem is now I will install a ceiling fan with light fixture. As I have not installed this yet none of the wires are connected. Leaving the wiring for another day I went upstairs only to find that the bed room had no power. Could this fixture and the bed room be a series? Why would a room upstairs and a room downstairs be electrically in line?

Hi, first post here and hope someone can help me out. I have a circuit that is 20A that is feeding 9 outlets. I have three fish tanks running off this circuit, and have never had a problem with it tripping the breaker for the 1 1/2 years the tanks have been running. I just noticed lately though that 3 outlets feel warm to the touch. These 3 outlets are the first of the 9 and they have nothing plugged into them. The strange thing is, the last 2 outlets that have nothing running on them are not warm, neither are the outlets that have the tanks running off them. Just the first 3. Now I looked into the wiring, as it's in the basement and found that this circuit is feed from a 12/3 wire that is running 26' from the panel, and it splits off into two circuits of 12/2 at the first outlet. The circuit in question has another 36' at least after this split. So, my main ? is, is the warm outlets a concern? The breaker doesn't trip and doesn't get warm either. I haven't added up all the power yet, but plan to do so, art least add up the watts being used. Will that help, or does it need to be the Amps, not the Watts?? Also in ? is the 12/3 wire. I can run two 12/2 wires straight from the panel and not use the 12/3. Would that help any? Does sharing the white "common" make a difference? Sorry for all the ?, but hopefully one of you here can help me out. Thanks -steve
