I’ve watched over 20 different dudes explaining hooking up 3 way and they always start half way through or they go to fast, they don’t show and explain where flow goes every wire every step of the way. I had only 14/2 hooked up between my 2 )3-way switches on 1 light. Had 3 different 14/2 wires coming into secondary switch. Holy fuck was I lost because everyone on KZfaq shows you with a 14/3 going from switch to switch. Because of your video and my multimeter I was able to determine it was the first example and was able to safely hook up my new led dimmer in the secondary switch. My wife is so happy and so am I with my new slim disk led lights. Thank you thank you thank you for being an actual teacher who covers everything include materials needed and then finally a label of wires.

@austentownsend5612 2 жыл бұрын

This is a great video explaining 3 way switches. I have a few other comments to add. In your presentation you say put the black travelers on the left screws and the red travelers on the right screws. Left or right doesn't matter, you just need a pair of wires between the traveler screws. Also, looking at the 4:42 point in the presentation, I prefer using the black wire going to the right switch to connect the common terminal to the light fixture. Then use the white wire to the right switch as a traveler by connecting it to the black traveler from the left switch at the light box. Doing it that way, you will have a black wire and a white wire to hook to your light fixture.

Found it. I’m installing a new light switch on the other side of the light and at 4:00 I found the exact circuit I’d be wiring. I ran wire for 3 years but I didn’t do any finish wiring so I didn’t know to cap the black and white at the light box but I knew that eventually in my circuit Common would be Hot. This explained EVERYTHING I needed to know to do the job. I enjoy many of your videos as a new technician training myself in all trades at a very large apartment complex. My bosses know I have the ability to troubleshoot so I’ve been forced to learn on my own. Well partially on my own thanks to Grandpa KZfaq and all his infinite wisdom. Thanks for the video and to all of you who produce boring ass content like this lmao.

@peterkilleen3061 3 жыл бұрын

Good video, with good diagrams and clearly explained and spoken. But only 99% concise... to make the video more accurate, he shouldn’t be saying ‘electricity will flow up to the second switch which is broken’ - flow indicates a flow of electrons. Not the case for a broken circuit as everyone should know, you need a complete circuit for current to flow. He should really be saying ‘the circuit will be energised up to the broken point, no current can flow due to the broken circuit and the light doesn’t illuminate. Flicking the switch and Closing the open point completes the circuit allowing electricity to flow. This would be accurate and completely concise. Good video all round, but some better terminology needs to be used to be completely concise

Technically the second method and third methods are no longer legal. As per the NEC 2011 404.2(C), All switch boxes must have a Grounded/Neutral/White conductor in the box. Unless you want to spend the money on 4-Wire just wire it up using the first method. They did this due to the new presence of electronic switches. There are 2 exceptions, the first is if the box is attached to a raceway that could accommodate another wire, the neutral, at another point and not be a breach of their being too many wires in the conduit. The other exception is if the area behind the box is readily accessible without chipping away at the wall.

@sunnyjerry 3 жыл бұрын

[Method1] PRO: Always has a neutral wire in Switch Box to comply with NEC code for newer types of Switch which need neutral wire plugged into Switch. CON: May need to spend extra money for 14/2 wire from Switch Box2 to Light [Method2] PRO: May save a little bit by not spending money on extra 14/2 wire from Switch Box2 to Light. CON: (1) Generally, may not save too much on wires because it needs 14/3 wire from Switch Box1 to Light then to Switch Box2, and this whole route is generally longer than direct route from Switch Box1 to Switch Box2, and 14/3 wire is more expensive than 14/2 wire. (2) Does not have a neutral wire in Switch Box to comply with NEC code for newer types of Switch which need neutral wire plugged into Switch. [Method3] PRO: May save a little bit money on 14/2 wire under certain location placement. CON: (1) To start circuit from a Light to Switch Box, instead of from Switch Box to a light is less intuitive/less common. (2) Does not have a neutral wire in Switch Box to comply with NEC code for newer types of Switch which need neutral wire plugged into Switch.

@usmarinekenny 2 жыл бұрын

@TMWSTW1984 the 2nd option is legal as far as the neutral is concerned as it is only required in one of the switch boxes not all of them, but does violate 200.7(C) where the re-identified white wire can’t be used as a return hot or switchleg back to the light as the way he has it now there are two white wire attached to the light one being re-identified and that can’t be and must be switched with the black on the traveler screw so the black coming from the second 3 way would be connected to the common terminal and to the light on the opposite side side and the re-identified white would be attached to the black coming from the traveler of the first 3 way to comply with the code, and option 3 is the only one I saw that didn’t have a neutral in either of the switch boxes.

@cdecoro 2 жыл бұрын

@@usmarinekenny To be clear, it is acceptable to have the neutral in only one box where that box has a view of the entire room. The text is “Where multiple switch locations control the same lighting load such that the entire floor area of the room or space is visible from the single or combined switch locations, the grounded circuit conductor shall only be required at one location.”
