Wiring Help

Helped a friend who had a bad single switch in living room. Here is the deal:

Single gang box which had three wires run into it:

Wire # 1 - Source / From Panel - White, Black, and Ground

Wire # 2 - Ceiling Fan - Black, White, and Ground

Wire # 3 - Wire to receptacle controlled by switch - Red, Black, White, and Ground

How would you go about wiring it? Can it be done to fit code?

redcx9: I assume you mean that Wires 1,2,3 are actually Cables 1,2,3 and switch is intended to control Fan and receptacle.

Source Black to one side of switch (point A)
Source White and all White wires nutted together
Fan Black to other side of switch (point B)
Receptacle Black also to point A
Receptacle Red also to point B

Hence, the switch controls the Fan and 1/2 of the receptacle. The other half of receptacle is always hot.

Yes, I am sorry. I meant cables. So it is legitimate to run 3 cables in one box off a single switch? The switch has two screw terminals and 2 push in - rear entry terminals.

When you think you want to run two wires to the same screw of the switch or receptacle, or run the two wires to one screw plus one hole extremely close in the back, do this instead:

Take the two wires and a short length of wire of matching* color and wire-nut the three together. Connect the other end of the short length to the screw terminal.

* The short length (pigtail) must be white if the other two wires are both white. Use green only for ground wires for which one end must be attached to the framework (yoke) of the switch or receptacle.

* Feel free to use the holes in back provided that the turn of a screw is needed to keep the wires in the holes.

* When a white wire is connected to a switch (rarely happens unless the black wire of the same cable is connected to the other screw) both ends of that white wire must have a band of black or red tape or stain applied.
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.

I would lose the switched recep (make it hot) and just switch the fan.

All whites together.

Source black and recep black together with a pigtail to one rerminal on switch.

Fan black to second terminal on switch.

Use the screw terminals.
