Default Wire for 0-10v dimmers

What are you running for wire for new construction were LED lights are going in and are being dimmed with 0-10v dimmers? I've been using 14/2/2. Was wondering if something worked better?

That may or may not be compliant. I ran 14/4 but I also ran a 12/2 low voltage class 3 wire. Sometimes the high and low voltage needs to be separated.

I know that south wire makes an armored cable specifically for this but who wants to do that in a house. It may be the safest way to go.

It depends on class on the conductors on low voltage side .,, some can run together with line voltage but some can't.

check the manufacter for their specs to make sure you are hitting the right spot .

and few spots the low and high voltage connections have to be seperated too so just be aware of that. ( same with multi gang switch box watch that part too )

Good question. I know you can get MC cable with a gray and purple for that purpose. Is romex available that way too?

Kinda of that the XX-4 or XX-2-2 will work if your unit can work together like that.,,

but yes If I recall it correct there is couple Romex that have specail coating that used for low voltage purpose but I am not sure what they are called now due I am in diffrent country now so I will be lagging a little but not that far behind.,,

I know what you mean about the foreign country --stuff lagging behind cause I called into the building dept. a few weeks ago and yup, we still be jammin the 08...........

Canada does not have 14/4 or 14/2/2 romex; only have 14/4 AC90. Would be nice to have the NMD90 4 cond for bathroom fans with options.

Cheers
John

Am I right in gathering that there are two separate issues, inside the box and outside the box.

In the raceway, conduit, etc. control wiring can be there as long as its insulation rating is sufficient, but there are no other exceptions.

If the control wiring is only for lighting control, which would be the case for dimmers, it can be in the same enclosure - even if the insulation is NOT sufficient for the line voltage - as long as it's routed 1/4" away from the line voltage.

So if I have this straight, that separation is easy in a panel, you can just sleeve the low voltage with some carflex or whatever. But in a switch box or etc., I don't realistically see how you're going to keep them separate.

So if you have to have line voltage and low voltage control in the same switch box shouldn't you use cable OK for line voltage?

The blue MC made by AFC will IMO be superior because there's a twist on the 0-10V cable which will reduce the induction of voltages that will screw up the dimming.

What is this wire Splatz?

I'm looking at 0-10 dimmers that need to be fed (from the fixtures down to it) , as well as carry the low V to the driver

I did see it not too long ago and I like them pretty good and only gotcha I have is.,, I have to jump one island to the other island to get this.,,

But I did talk to my supplier in my main island so he will set it up so I can able get it without end up hitting ferryboat charges .,

most of my jobs have been commercial with MC so we used the special MC but I've used Romex with separate 18-2 in a house.

have to ART 725 carefully

Basically, the answer is find out who made the controls and follow their recommendations, as well as the code rules for (usually) class 2 low-voltage wiring. This is a discussion for some Acuity drivers: https://www.acuitybrands.com/product...ntrols_pdf.pdf

That said there are a few general pieces of advice that probably apply for 0-10v analog signaling; for digital signals, find out what standards are being used and follow the applicable recommendations:
  1. Typically drivers will draw 10ma or so (this might be as low as 2ma or as high as 50ma.) They can be ganged in parallel, and controls can put out as much as 500ma (0.5A.) You don't need heavy wire for this; 18/2 is probably enough in most situations, however, watch out for long runs or high currents that can result from many ganged dimmers.
  2. Because these currents are, relative to controlled power, low, it is best to use pairs of wires with a grounded shield; otherwise induced currents from power equipment can affect the drivers. An air conditioner motor near the cable might, for instance, cause the lights to brighten when it turns on or off.
  3. If you have more than one 0-10v pair in a cable, make sure they are individually shielded; otherwise you may get crosstalk between the controls when levels are changed.
