Richard, Without tearing apart my kids' bedroom outlets (mainly because I am at work) I have seen red wires and black wires in the box for the room switch, and they are on the same 120 V branch circuit. If I recall, the electricians wired a red and a black wire to the ceiling box so that I can one wire to one switch (lights), and the other wire to a second switch (fan). I wired all the ceiling fans, and they work! This may have been done to the switched outlets, but I know I rewired the outlets to be unswitched.
There is nothing in the National Electrical Code forbidding you from using any colors for the live conductors, except white for the neutral (and some similar colors like slade gray), and green or green/yellow for the ground. It is customary to use black and red in single-phase residential applications. Regarding duplex receptacles, where one side is switched, and the other is not, the way that is done is there are two built-in jumpers connecting the lines and neutrals that can be cut by the electrician if he wants to split the outlet to make one side switched.

Also all 4 outlets in the room are controlled by the one switch is the red wire some time of connection between outlets only and not fed back to the breaker box? that's my thought. any ideas on this? thanks Richard, From: [email protected] [mailto:[email protected]]On Behalf Of [email protected] Sent: Monday, November 21, 2005 5:24 PM To: [email protected]; [email protected] Subject: RF links Rich, Here is a link to some good RF sites.
