Adding 4 Recessed Lights to single wire


Here is the scenario

I have a single switch on the inside of my house that controls a single light outside on the patio. I was looking to put 4 recessed lights outside in addition to that single light. Here is the problem

I can take the current 12/2 and split that into the wiring for the 4 lights. However, how can I get power to the ceiling fan. I was thinking that I could take the main line that was feeding into the switch and splice off of it and wire a second switch and a new wire to the new panel. Could that be done? Or how else can I get the fan/new lights to work separately??

Remove the single gang switch box and replace it with a 2 gang box.

Run one cable to your lights and one cable to your fan.

There are more ways to accomplish this but that is the basic setup.

I was going to run the two seperate wires, but how would each new light swtich be powered seperatly by the single 12/2 coming to the current single light switch? Is there a switch that is a single in and double current out (seperate current) one going to the 4 recessed lights and the other to the fan?

In your switch box you will install 2 pigtails (short pieces of wire) to the hot (black) wire with a wire nut. This gives you two hot wires to hook to two switches.

The black wires from the cables going to the lights and fan go to the other terminal on the switches.

All a switch does is connect/disconnect the flow of electricity thru the black wires, up to the lights/fan.

Whites all tie together.

Grounds all tie together.

That is where my question is. Will i be good at splicing the single 12/2 into two seperate black/white lines (One to the fans and one to the new 4 recessed light boxes) so i would have two "hot" switches in that new 2 gang box?

Yes. The wiring is spliced at almost every recep and switch box in tour house.

Open up and take a look at an existing 2 gang switch box to get a better idea of how it's done.

If you don't get techinical about it, on a simple circuit, power comes from the panel/circuit breaker on the black, and returns to the panel on the white. Along that path it heats up a filiment white hot to provide light or provides an electromagnet to run a motor.
