Confirmation of wiring


Just looking for some confirmation along with an answer to a question.

I've wired a circuit in the following order:

1. Panel
2. Light box (ceiling) Supply + 3 x 14/2 wires
3. Wire 1 - goes to switch (for the light at this electrical box)
4. Wire 2 - goes to outlets (3)
5. Wire 3 - goes to another outlet/light

I've attached a diagram to make it a bit easier. Could someone please confirm that it is correct?

Question: Does it matter at the switch whether the white is on the top screw or the bottom screw?

make sure you remark the white wire used as the switch leg as a hot wire.

the other light has it's own switch, right?

on the switch; doesn't matter which screw the hot/switchleg is attached to.

I may be wrong, because I get this mixed up sometimes; but I think you need one small change:

At the junction box in the middle of your picture, the two wires from the cable labeled "Switch" should be swapped. The white (marked black/red/whatever) should be the constant feed to the switch, and the black should be the switched power from the switch.

I don't believe I know the reason for this, but there you have it.

This is 100% correct.

Thank you and I will change it as suggested.

Is this a safety issue or is it a consistency issue?

I have marked the wired by covering it in electrical tape (I didn't have black so I used green).

In addition, the other light has it's own switch, I'm just labeling it to make it easier to understand what I've done. That is the supply line for the next light.

If I open up a junction box and find a white wire nutted to three black wires I would know it is a switch leg.

Green is not acceptable.
Use a black marker.

Okay... I will change it all to black.

Curious: What is the problem with green. I figured it was okay because it was still electrical tape.

The NEC reserves green for grounding conductors.
