Valid Circuit Diagram


I live in Hattiesburg, MS, and I am extending a 20 amp circuit that is currently only supplying power to 2 unused receptacles. This extension will supply one more receptacle and 3 lights (switched by a single-pole switch). The layout of the devices is a bit odd:

Source - Light1 - Light2 - Receptacle - Switch - Light3

I do not want the receptacle to be switched. Here is a diagram that I think will work, but since I could not find another layout online similar to this, I thought I'd first ask if this is acceptable.

The blue lines are neutral, and I did not include ground wires in this diagram, but assume everything will be properly grounded.

Thanks for the help!

Welcome to the forums.

Your drawing is correct. Nice job !
The use of the three wire cable will carry switched power back to your lights.

Welcome to the forums!

That looks like it should do what you're trying to make happen.

I guess I was only really concerned with the neutral path. I have never wired a receptacle in the middle of a light run and wasn't sure if that neutral path was okay.

Thanks for the quick response!

What room is this circuit serving? Most 20 amp circuits are limited to what they can serve. some cannot have lighting on them.

It is serving a covered back porch. The 2 receptacles existing on the circuit are in a hallway. Inside, the wiring is 12/2 romex. It will change to 12/2 THHN traveling through gray pvc conduit once it leaves a jbox in the stud wall and goes through the cinder block to the back porch.
