![]() ![]() It fits in boxes better, is easier to manipulate and work with etc. Also a lot of people prefer working with 14/2. Many times it is a good money saving option if you have a lot of lights to wire but the switch box is fed with 12/2. Diagram 3 is an old style switch loop on the left (not to current code) and an always hot receptacle on the right (which is OK, but irrelevant).There are a few situations one might see the need to use 14/2 wire with 12/2 on the same circuit.The black marking on some of the white wires is because white is being used as hot instead of neutral. But new installations are not permitted as code now requires neutral at the switch, which this does not provide. Existing installations of this type are grandfathered and perfectly safe. Diagram 2 shows an old style switch loop.The brown (bare copper) wire should be connected to each box if you use metal boxes, and does not need to be connected to the switch if you use metal boxes. Diagram 1 shows panel -> switch -> lights, which you don't want (but is legitimate).īut as requested in a comment, here is Diagram 1 expanded to include a third light:.3 for a shorter distance (panel to lights to switch). The tradeoff is, essentially, /2 for a longer distance (panel to switch + switch to lights) vs. However, that is not compatible with "power goes to lights and then to switch". The way to use the least actual wire may be to use /2 cable instead of /3 cable. Switched hot (from switch, connects to each fixture) is red, by convention and not code.If you ever put in a smart switch that needs neutral, you're ready for it. Neutral is white, by code, connected to every fixture and left available in the switch box (recent code).Hot (from panel, chained to switch) is on black, by convention and not code.Switches get ground automatically if in a metal box. All grounds are connected to each other, to the box (if metal, as it should be) and to the fixtures. Grounds are not shown, but every cable will include one (normally a bare wire in standard NM cable).Is the final image below correct, safe, and to code, and does it have any special considerations for grounding? If you have a diagram like the first three, that would be super easy for me to understand. I find the first three images easy to understand. I found the one below, but it's confusing to me because I don't know what the red is, and I'm not sure if grounds are included in it. I'm not an electrician, I'm just DIY, so having a diagram that shows what I need would be very helpful. But I don't want the power source in the middle, because the place for my switch is furthest from the power source: This diagram below is the closest to what I need that I've found, if we pretend the outlet is a light. This diagram below is close, but I want another light in between the switch and the light: This diagram below would be ideal, except I want the power source to come in to the right-hand light from the right, and continue on to the left: I just want to show where the switch, lights, and cables are. This would be the best way to use the least amount of wire.įor the first 3 images below, disregard the wiring. I want the power to start at one light, which is furthest from the switch, and then continue to the next light, and finally end at the switch. I have one switch and two lights for that switch. I'm not sure if what I want to do is possible, as I've Googled this for a long time and I'm not coming up with any answers. ![]()
