Need some help with wiring (House)

I want to start by recommending you get a proper permit for this work dependent on where you are located. I hope my sketch attaches to this post as this won't make much sense without it. I have never tried to attach a PDF to a post before. If it doesn't feel free to PM me your email address and I'll send it to you.


Light 1

• Attach the bare copper wire from 2 wire cable “A” to the junction box bonding screw. Connect the free end of that wire to the bare copper wire from 3 wire cable “B”. If there is a bare wire, green wire or green screw identified as ground on the fixture connect it to the bare bonding wires as well.
  
  
• White to white (Include white wire from 2 wire cable “A”, 3 wire cable “B” and white on light fixture)
  
  
• Black on 2 wire cable “A” to Red on 3 wire cable “B” (Caries power to the switches)
  
  
• Black from 3 wire cable “B” to light fixture

Light 2

• Attach the bare copper wire from 3 wire cable “B” to the junction box bonding screw. Connect the free end of that wire to the bare copper wire from 3 wire cable “C” and 2 wire cable “D”. If there is a bare wire, green wire or green screw identified as ground on the fixture connect it to the bare bonding wires as well.
  
  
• Wrap white wire from 3 wire cable “C” with black tape. This is no longer a white/neutral wire. Connect it to the fan wire on the light/fan fixture.
  
  
• Red to red (Caries power to switches)
  
  
• White to white (Include white on 3 wire cable “B”, 2 wire cable “D” and the light/fan fixture.)
  
  
• Black to black (Include the black from 3 wire cable “B”, 3 wire cable “C”, 2 wire cable “D” and the light wire from the light/fan fixture.

Light 3

• Attach the bare copper wire from 2 wire cable “D” to the junction box bonding screw. If there is a bare wire, green wire or green screw identified as ground on the fixture connect it to the bare bonding wire as well.
  
  
• White to white
  
  
• Black to black

Switch box

• Attach the bare copper wire from 3 wire cable “C” to the junction box bonding screw. . Connect the free end of that wire to the green bonding screws on the switches.
  
  
• Red wire will be common to the bottom of both switches.
  
  
• Black wire to the top of the light switch
  
  
• Wrap white wire with black tape. Connect it to the top of the fan switch.

Always remember to run the bare wires so they do not come in contact with the exposed live electrical parts in the box such as connection screws. This will cause the breaker to trip and may cause other damage like burned off wires etc.

I would recommend a deep box for light 2 since there are additional connections needed at that location. Dependent on the codes local to your area, it may not be necessary but it will definitely be more convenient for you.

As was suggested above, a timer on your bathroom fan is a good idea. The timer will directly replace the fan switch but if you chose an electronic timer over a spring wound timer you will need a 4 wire for cable “C”.

Remember, when buying household electrical wire, it always only counts “Current carrying conductors” so a 3 wire means 3 “Current carrying conductors” and the bare ground.
