I wired up the new switches in exactly the same way as the old. It could be some combination of C, D and E for all I know. A common, either 120v power or the wire to the light fixture. I have one line going to the fixture ( D), but I haven't verified it yet. Yes a 3 way switch can be wired using a marked white wire (not a neutral) provided your 3 way switch has the following 1. I don't know if there is a junction or anything else along this, but it does connect through. I assumed C by turning off power, then checking continuity with a multimeter. With the two wire version you just turn one switch through 180 degrees and it. Verified both are hot with main on with a multimeter. The three wire versions only virtue is having both switches the same way up. I verified A is connected to B by turning off main, then checking continuity with a multimeter.
#3 way switch with 12 2 wire series
It seems like 3 way switch in box 2 was wired in series with the rest of the circuit. My next task (tomorrow) is to open up the fixture and see how it is connected. Is my assumption correct? Is Carter the only one with main/hot to both switches? If so, what do I do from here? I'd rather not wire up another Carter setup.Īdditional information: I've attached a picture with what I've discovered.
#3 way switch with 12 2 wire code
A little disturbing, as this house was build in 1970, and Carter hasn't been code for ages. The only thing that I can figure is that it was a Carter system, as that is the only diagram that I have seen with hot/main into both switches. By that, I mean that with no switches installed, each box has a hot pair into it. Each switch box has a hot line coming in. After removing the switches, I did some testing. As soon as I looked at the old wiring, I got confused. Very simple setup - two switches, one fixture with four lights. I recently installed a bathroom fan, and so had to replace two three way switches. The Leviton Decora Edge 15 Amp 3-Way Switch, White is exclusive to The Home Depot. relay to 3 - way PAOZZ 6145-0 7056678 switch ( early model ) WIRE. I have tried with 5 cheap switches and then 2 of the higher quality switches.I've read up on three way switches, and have replaced a few over the years. ( 1 ) Illustration ( a ) ( b ) ( 2 ) ( 3 ) ( 4 ) ( 6 ) Description ( 7 ) ( 8 ). The black wire that is coming from the light is connected to the common of the second switch. the black and red wires from the 12/3 feed are on the travelers for both the first and second switch. On the second switch, I connected the white wires together, and then the copper wires together. Kasa Smart 3 Way Switch HS210, Needs Neutral Wire, 2.4GHz Wi-Fi Light Switch works with Alexa and Google Home, UL Certified, No Hub Required. There is a copper wire also connected to the switch itself on both switches. The white wires are connected to each other and the copper wires are connected to each other. I connected the black and the red wires to the travelers on the first switch and to the travelers on the second switch. I have 12/3 running from the first switch to the second switch. I connected it to the common screw on the first switch.
The one trick is, before you disconnect any wires from an existing 3-way switch, make sure you find the wire attached to the common screw terminal and. This black wire is the only hot wire when everything is disconnected and the breaker is on. wire stripper and wire cutting tool 14-3 or 12-3 cable 3-way switches Neon Circuit Tester. NM 12/2 - 12 gauge wire with a yellow outer jacket enclosing 2 current carrying conductors and a ground NM 12/3 - 12 gauge wire with a yellow outer jacket enclosing 3 current carrying conductors For this guide we are going to assume you will be working with 14-gauge wire, though it is possible to have 12 gauge wire. I have 12/2 coming from another switch on the circuit to the first switch on the 3-way circuit. When I connect the black/hot wire to the common of the first switches, both travelers are live. I believe I understand the wiring clearly but I've replaced it with several new switches with the same symptom. I am installing a single hall light on a 3-way switch.
