existing new LEDsHave a basement with 4 beams that had 2 lights in bay 2 and 2 lights in bay 4. Dropping ceiling and want 3 LED lights in each bay. Can I run 3 new 12/2 wires to bays 1,3,5 which will be spliced to the old 12/2 rerouted from bay 2 and new wire ran to bay 2 in a new junction box?

  • Hello, and welcome to Stack Exchange. It's difficult to know what you mean; would you add a diagram to your question? – Daniel Griscom Jul 6 '18 at 20:43
  • What makes you believe you can't? – ThreePhaseEel Jul 6 '18 at 22:10
  • Well the diagram now looks like you want to do more than add a light to each of those bays. What is it that you are really trying to do? – Ken Jul 6 '18 at 22:30
  • those are 2 different diagrams, bottom is existing, top is the way I want to do it – user87466 Jul 6 '18 at 22:36

    Your top drawing does not make sense - do you want the lights to operate like a regular 3-way switch wiring would operate? If so the top drawing does not look like it will do that.With the J-Box you only need to supply voltage from switch to j-box as if it is 1 light and the j-box feeds power to the Lights - see normal 3-Way switch and make like J-box is your light. What LED's are you using BR30 Recessed Light equivs, or something else ? Post a link to it or a picture of it - make/model is helpful if you don't use a link. – Ken Jul 6 '18 at 23:21

Here are some samples for how a 3-Way switch is wired.

Depending on how your power comes in via the switch or the lights will determine what to use. Basically the Ceiling Box in the diagram is your junction box and the Light in the circuit is all of your LED's you are running from that Junction box. Remember you can't just put 10 wires together and wrap them and claim it is acceptable by code. Daisy Chain your bay runs for your LED's (all led's in one bay are connected in parallel) - so you have 1 line feeding each bay (4 lines from the LED bays to the junction box [J-Box]. Those would be wire nutted together with the switch / neutral and ground. See the diagrams below. Depending on how your 3 way switches are wired up - will determine what you need to do and how to make it right and easy on yourself.

First Image is a brief look at what you should have when you are done.

What the Wiring should be similar to.

This is a 3-Way that depicts the power going through the switches.

3-Way Neutral through and 2 wire with ground

3-Way 2 wire

There are other ways a 3-way could be wired but I felt that this would be easy enough for you to follow and if you needed to (if yours was wired power through the lights for example) - you could research and find that.
