Wiring for dimmer circuit

[like2wheel]

Need to start the rough wiring for my pole barn shop. Probably using high bay LEDs for liting. How is the low voltage dimming circuit actually run?
Planning on roughing with romex, so do I just use 14-3 & recolor the red? Is the low voltage even allowed in the box? Or run some sort of separate circuit for the low voltage alongside?

Tried searching, but probably using the wrong terms.

Run an 18-2 thermostat wire along side your Romex.

3 wire Romex will not work.

Yep, separate 18/2 run will do the job. Not for much longer though, wifi control is already becoming more and more common,just a matter of time before all LED fixtures have this capability.

Is it ok to put it under the same staple?

I might be confused about the type of lights you want to use, but I have installed quite a few recessed dimmable LED lights lately.

Are you going to use lights that have one voltage converter to provide the low voltage power for multiple lights? The design makes sense, but I have not seen it for ceiling lights.

The lights I've used are wired to AC like any other 120 volt light, using an LED compatible dimmer at the wall switch. Each light has a small junction box with the electronics to convert 120 volts to low voltage for the LEDs. It also serves as a 120 volt wire junction box. There is a short low voltage pigtail (about 8-10" long) that connects the box to the light housing. The pigtail unplugs so you can rough-in the housings and install the lights later.

Only residential lights use the 120v supply to dim. It is kind of a major work around so they will work with existing wiring.

Any commercial fixture, like a high bay, uses a separate set of control wires to signal the fixture to dim. These wires do not power the fixture. This is commonly called 0-10V dimming because of the voltage used.

FYI - the dimmers for the 0-10 high bays are not cheap. I paid $50 each.

They work well.

you need 2 conductors just for the dimmer control

Have you considered using MC? you could get MC-PCS which has 2 conductors just for the low voltage control circuit

Look up 0-10v dimming. it requires a 2-wire low voltage control circuit that is ran to the dimmer.

Eaton SF10P or DF10P are 0-10V dimmers with 120v ON/OFF in one device. Looks like a normal slide dimmer. You can bring your power and your low voltage to it.

I have 7 of those but don’t think code allows thermostat wire in the same box. I think you need the 18-2 wire to be rated a certain voltage to be in the same box as 120.

Thanks. Didn't know about that stuff. Pricey tho, wonder why it doesn't come in 14 with everything led these days.

cuz commercial buildings use 20A breakers

Southwire has an NM-B Romex version for 0-10v dimming. I have not found it in any of the big boxes, but a supply house might have it.

Does anyone have experience with these Lurton dimmer modules?https://www.amazon.com/dp/B07D95RRQS/?tag=atomicindus08-20

Paired with the Pico remotes?

I’m looking at this option for my up coming build.

The best solution made. Lutron is the leader in dimming technology for about 4 decades now. Vive is their newest creation and it works beautifully. Good choice.

Wow - Thanks. They have 14 awg as well. I would have bought that in a second. I didn't know it existed.

 

[ace10]

Yeah, that Romex is slick. Def woulda used that in my construction a couple years ago.

For 0-10V on my LEDs, I'm using Legrand Adorne switches. They're not smart switches, but I don't need that in my detached space.

I’m wiring my building right now. 32 high bay fixtures. I’m doing the dimming with 18/2 thermostat wire.. only $55 for 500ft.

I bought 3 of these dimmers for separate zones and it works. I’m going to add a digital volt meter so I can repeatedly set it at the same dimness if I desire. These are under $10..

It successfully dimmed 2k watts of the highways without issues.

I used the following and appear to work great.

Lutron Diva C.L Dimmer for dimmable LED, Halogen and Incandescent Bulbs, Single-Pole or 3-Way, DVCL-153P-WH, White

Can I use the 22 gauge alarm wire I have to wire my dimmer circuit?

Not sure how much current is used but I have a bunch left over from when I built my house
