yes Gary

But that's all about convincing an archy ,some of which aren't very 'flexible'

Speaking of architects...

In my business (PV design) I often have to port a set of architectural pdf files into AutoCAD to build rooftop layouts. I had always thought that architects were all anal to a fault about precision, but what I have seen often says otherwise. I see lines that are obviously meant to be orthogonal or parallel which aren't... quite, lines that are obviously meant to converge but don't... quite, measurements that aren't precisely what they say they are at the scale they quote, etc. It's frustrating at times.

When you go to the site URL that's posted, click on the video on the same page and listen to what he is saying as he installs it. It's around the .50 second mark. The guy clearly states it's for Fire alarm and Cameras. I went there looking for this. No way the drop ceiling could ever be bonded in a way that if there was a fault in this box could it be relied on to trip the breaker. At least the drop ceilings I have dealt with.

Please post where Galvin is saying it's for lighting, fans.

Thanks,

Gary

Check out “product description” below that video.
Only thing I haven’t come across yet is if it’s listed.

Are these PDF's that were produced straight from AutoCAD or did someone scan the drawings? For some reason, scanned PDF's are still popular.

The ones about which I speak are straight from CAD. I get scanned pdfs from time to time and they really suck.

If you're not Anal, you are not an Architect! lol.

These poor guys are squeezed between the owners, Generals, Subs, and Lawyers coming after them for something. They are in the cut and paste era now like the rest of us. I'll look at a set of new drawings and see the spec of another project with the exact same errors.

It's a tough business and I have a lot of respect for these guys.

ggunn'; what version of AutoCad are you using?

I listened again. He says, "not recommended for high voltage"

Why would you not recommend not installing this product? You would think he would want to push his product out as much as he can.

I wonder what Mike would think about this one.

If Mike says OK, I'm OK...

In the 80's, I would say, Mike, can't be right on that. He was.

In the 90's, no way Mike can be right on this. He was.

Now, present day, forget about it. Whatever Mike says, it's correct!

I was quite anal about my measurements for column placement, stairs design, etc, on my house I am building in Jamaica.. Designed it to specifically address the situation of neighbors property line, etc, and maximise the space.
However, was in another country and let local architect handle the foundation, and basement, trying to keep employed so could pay for it. Did things like design stairs around common building materials to cut down on cutting forms, so everything could be rented...
Hallways designed to be exactly so many tiles wide, etc.
Get there and every measurement off. Everything has to be custom. Instead of the whole blocks many times part blocks and wastage
So... It sometimes is not the architects but the builders that cause all the headaches when you later try to do stuff.

Do you think, when he says high voltage he's talking 4160 volts?

To this guy, 120 volts IS high voltage as opposed to thinking Fire alarm and Cameras.

I would think some common sense should apply here.

Low, medium, and high voltage are defined in the NEC, are they not?

You are taking the guy literally on what he said.

Gavin does not recommend you put lights on this product. They are saying, use this application for Cameras and Fire alarm. To me, that's anything at 49 volts and below. I can not see this any other way. Now, the guy screwed up using the term high voltage in the NEC term sense. This is a smo on a ladder at Gavin industries with a pair of dikes in his hands showing installation, not a code class. But, when he says not to use this product for X, I will listen. Especially since I think you could kill someone using this in lighting. Nobody here on this site has showed me where this drop ceiling is bonded by code and will trip a breaker under fault.. Crickets. If I were wrong, I would hear it...

I don’t disagree, but the way he throws around the term incorrectly makes me question his competence entirely.

I don't think 4160V is high voltage, either; I think that's medium voltage.

There is this:

They also come with labor saving installation and mounting tabs that align with most lighting fixtures.

K8HMZ, you are a smart guy. Can you please show me how I arrive at an answer to this problem. I sitting in a test for a Masters Electrical exam.

Article 314.

Let me know how many wires, of #12 THW I can install.

I'm having a heck of a time finding the volume of T-Bar here.

Thank You

Answer: 0

No need to look for T-Bar volume. It's a non-standard box and the volume is not marked on the box. 314.16(2)
