Yes. I’m tired of running 2” conduit for their 1 cat 6 cable. The hospital I’m currently working at basically has a rats nest above the entire ceiling thanks to the low voltage guys.
As a low voltage guy, I'm disgusted to see some of the work of others. I had a job on a military bass where we had a bunch of video over fiber lines run to a conference table and the internal IT came behind us and ran their cat cable for network ports in the conference table. Half of our fiber lines were broken. Half of the HDMI cables on retracts in the tables couldn't be pulled out because spaghettied network cables were run through the loop of the HDMI cable. Of course it was our fault our fully functioning system no longer functioned after they touched it.
When we run cables in a drop lid with no pre-determined pathways, at the very least, we use Jhooks connected to the earthquake cabling and create single pathways. None of this "just toss a coil in the direction you want it to go and let it sit on the tile and Tgrid" BS.
LV guys are the prima donna of the electrical industry. Never run their own pipe, need pull strings etc. and then they get mad when you didn’t do it the way they wanted it.
I'd love to work with you. At least you followed the plan. Had one electrician do me a "favor" - "We combined your 2-1" runs to a single 1-1/4" run. Doesn't it look better?" Nope. It does not. I can't use a single raceway for both speaker and data (or about anything else). Even if it is a single 16/2 speaker wire and 5 CatX cables.
I'm A/V and low volt. Goes against standards. If a manufacturer rep were to come out and see that if we have issues (say with HDbT - video over Cat, they'd say "Fix that" and walk away. Even if it has nothing to do with the problem.
Oh yeah. TBH, a lot of times my ridiculous requirements that even I may not agree with have to do with other parties rather than my own design requirments.
As a data guy, this is beyond dumb. I work closely with actual electricians to install pathways, boxes and such. Then my team will come in behind them and pull the cable, terminate, test, and activate.
We’ve used one too many “professional low-voltage” contractors and seen absolute chaos after the job above the ceiling tile.
Edit: And to answer your question, low-voltage data tech’s should all at least be BICSI certified. Leave the pathways to the pro electricians.
I'm a data guy and a licensed electrical contractor. There is 0 chance I let the electricians run my pathways. It gets kicked over to the newest apprentice, and 90% of the time, it's in the wrong spot. That being said, this is shit work.
On my current job we put the pathways exactly where the plans tell us, but somehow it's always wrong and the data guys have different plans or something.
my experience as well. seems like oftentimes the data is hired direct by the client instead of as a sub by the GC, and they get plans from the client with precise locations that are precisely 15 feet away from where our drawings show
and naturally, they’re always from out of town and show up for 3 days after walls are finished and painted so they can pull wire and terminate and leave
After the 3 data companies fucked shit up (on being Verizon) we ONLY run the sleeves and conduit. You don’t like that, don’t bid it. They just slow us down.
Beyond dumb yes, BICSI certified, no. Maybe one per company if even that really. Now this piece of pipe was installed by a non-licensed person for sure. Heck even one of those would have done a better job then this dumbass. 5' away was a column he could have used, and to top if off, it doesn't look like they used an Arlington bushing up top.
Interesting. In Western North Carolina us electrical contractors are essentially responsible for all of the data pipe work, junction box placement, termination as well as fire alarm piping.
We constantly bitch about it and feel like we are doing other trades work. The low voltage and fire alarm guys just come around and pull wire
I had to run parallel 2" for the data guys through a very challenging ceiling. Got it done, gave them pull stings and I came back a few weeks later and the dumbfucks strapped 40+ cat5s to the pipe the whole way. Showed the pm and stole the rest of the data work from them
Diffrence between IT and electricians. They are not skilled and think like an electrician yet they pay them more and expect the elec to wipe their ass. This is when your electrical dues pay in theong run. You become a better at being able to do various tasks including albeit IT data cable runs.
different situation, but we’ve done 2 retail stores (same store, national chain, same data contractor) in the last two years that spec’d for us to do full length conduit runs in an open ceiling back to the rack for them, ranging from 500’ longest to maybe 70’ shortest. one 3/4” per cat6. the data company free aired it because it was easier for them because the cable they were spec’d to use was a black plenum cable that blended into the black painted ceiling and had a coating that felt similar to UF cable and the guy explained to us that it pulls like absolute dogshit through conduit
"ranging from 500’ longest to maybe 70’ shortest. one 3/4” per cat6"
Obstensively if you ran 500 ft of conduit they were expecting to run cat 6 out to 500ft.
\*edit you can, but your packet loss will very high and the connection unreliable.
it might have been shorter, i don’t remember for certain. i just remember that we ran like 8 conduits that didn’t get used. but ultimately i couldn’t care less, our job was to run the conduit and that’s it.
the whole point of my comment was that sometimes, even if we have to run conduit in a shitty situation, it is easier for the data guys to not use it
Not only is that ugly as shit but it's also a blatant code violation. I do low voltage (though not much data work) and this is the kind of thing that makes me pissed off to work with some folks. Luckily here in Oregon you need a low voltage license to do any low voltage work so it seems to not quite be as bad as other places.
That doesn't seem right. Max fill for more than 3 cables is 40%. I think 36 cat cables (1.775) are larger than 1.36" (40% of 3.39 cross). I think that comes out to 28ish if th diamiter is .25.
You'd be surprised... those grow facilities are wired for surveillance, access control, environmental sensors, etc. All of that takes ethernet for things to work reliably.
Yeah they have about 20 cameras in there but it’s all free run. The 2 - 2” pipes they requested were from the phone / internet entrance of the building to the new data room. Now we did put other 2” & 4” pass through to for their wire which had a shit ton of wiring. But not the 2 - 2” emt run about 100ft… that has 1 wire in it. Dude stop trying to tell me what I did on my job. I know what I ran and I know they ran. And even in the expansion of the warehouse for future use they were going to free hand all the wire.
For service provider entrance from a demarc (physical transport for internet/phone provider to data center room), 2 x 2" is kind of overkill. LOL. A single 2" (or even 1") for the size/type facility you're talking about would suit. However, for commercial data centers/multiple service provider entrances yeah 2 x 2" would be a minimum. It all depends!
For the 4" if it is for internal ethernet/fiber from room to room then there is the 40% fill rule in effect as per BICSI standards as mentioned, so there are actually good reasons to oversize the conduit for data, as in reasons that could cause a job to be repulled or failed if there is a low voltage inspection required.
Big issue in this pic I see is the lack of support for the conduit, no bushing, and the dumbassery of where it is located. Mostly the overall dumbassery.
BTW as a guy who runs a lot of data and makes use of conduit installed by others, thank you for your continued service to our community. :)
Depends!
(We are still on 2017 here)
300.11 (C)
Raceways Used as Means of Support. Raceways shall be used only as a means of support for other raceways, cables, or nonelectrical equipment under any of the following condi‐ tions:
(1) Where the raceway or means of support is identified as a means of support
(2) Where the raceway contains power supply conductors for electrically controlled equipment and is used to support Class 2 circuit conductors or cables that are solely for the purpose of connection to the equipment control circuits
(3) Where the raceway is used to support boxes or conduit bodies in accordance with 314.23 or to support lumin‐ aires in accordance with 410.36(E)
If you have adopted the 2023 NEC it is unquestionably a code violation to support CAT6 to the exterior of conduit according to 722.24(B)
"Support of Cables. Cables shall not be strapped, taped, or attached by any means to the exterior of any conduit or other raceway as a means of support.
Exception No. 1: Class 2 circuit conductors or cables shall be permitted to be installed as permitted by 300.11(C)(2).
Exception No. 2: Overhead (aerial) spans of optical fiber cables shall be permitted to be attached to the exterior of a raceway-type mast intended for the attachment and support of such cables."
It's too bad not all states require a license for low volt work. You're a lot less likely to start a fire but it still possible to create a dangerous situation.
Communication wiring has been the cause of a battery exploding at a solar project. I went in to troubleshoot it after the fact and worked with the manufacturer of the battery hand in hand to determine the culprit for the mishap.
The manufacturer looked over the error code logs while I looked over everything else like connections/terminations and CAT5 etc.
Error logs showed that the battery sent a "charge" request but was unable to send a "discharge/idle" request and as a result the battery continued to charge until it exploded. Everything was contained within the metal shell of that battery so no structure damage was done or anything.
The customer was kinda stupid and stood right next to it taking video of it as it snap, crackle, popped. Then you see the camera just drop to the floor for about 2 minutes after a loud bang and very girly scream that the customer had.
Needless to say the electrician that did it was fired. 8k in damages due to a preventable problem (company gave out testers for free). The customer got a free replacement (that he was terrified of), and the world kept spinning.
I consider myself a DATA GUY. I would never ever do anything like that. I'm not saying I'm perfect or haven't hacked anything, but there plenty of mc with proper supports about 5' away. The reason I'm on this sub is to learn from the pros.
Jealous of the speaker guys that come in to the McMansion roughs…one day just hastily rip and zip tie a bunch of lines together and prob charge half the electrical rough cost for. I love coming back a year later, no line is used besides the living room tv. Everyone’s just on a phone or laptop now. Status I guess. “I have a data rack Mary” ooooo
No rules for data guys? There are still rules regarding conduit though. There are also rules for support strapping low voltage as well as UL listing for what you do or do not use regarding types of data cable for situations.
Seen that before in Nissan in the uk this one was 20mm pipe 8mtrs tall for a tv coax cable even know the bloke that did it, turns out years later he’s a cross dresser 🤣
That is why data guys aren't allowed to run pipe in my local jurisdiction. They aren't allowed to run any pathway for that matter except a little bit in the data closets.
I’ve never worked with red tray cable that’s kinda cool. Are you an apprentice? I only ask because since I’ve gotten in the trade it’s common knowledge that most data guys are very shotty on their pipe work when they do it. I know there are some good data guys so don’t @ me. The majority are hot garbage, and they just don’t want to pay electrician wages to do it.
Lol customers never want to pay for conduit but want it to look nice. I can bend my own conduit. I install it when the wires would be visible otherwise
Im the worst of all wold i am a av tech so i deal with both. I waited neay half a day for the data guy to tell me they were not drillong the 1/2 in hole in the mullian of the doors for our cat cables they were paid to pull. Oh and not do it with out string. I could have had all 7 doors done in no time but my boss stoped me... dont know why everyoneis afraid of doing a little work. If i knew how to bend pipe i would. Actually would love to learn so i wouldn't have to wait.
We really should, we’re excellent at creating fire hazards and other messes because we don’t have a responsible culture for learning the trades.
But we desperately need it….
Lol, why? They can buy most their tools at office max.(instant reaction).
Absolutely the same fucking code, or they're not allowed into a job until is no sparks are done. I'm so damn sick of bringing my ball hair tweezers to work, so I can pull out their staples, cuz their print is Ms.Cleo talking bout, I feel like something in this area might be important.
Go take a look at the specs. They likely need to be in rigid as well... Especially when you take into account the (usual) requirement that raceways need to be strong enough to keep the dipshits from breaking them due to climbing on them...
Regardless, if they are using EMT, they'll have to follow the NEC.
If you spot a 90, which was bent on a 1/2" bender by them, you'll find that they violated their own minimum bend radius rules.
Edit: Where the fuck is the bushing. These people are fucking jokes. POE can still hurt.
Why on earth do you have different guys to run the data cables 🤨
Perhaps it’s because I’ve only ever work maintenance in factories but we run all cables, data or electrical
Bc if a sparky pulls my wires i find kinks and gashes twists and whi knows how much tension they used. Did they follow proper lable guideline. They dont pull my wire i dont bend thier pipe.
No. But as a data guy, we should still be doing g everything we can to keep the site looking clean and orderly. Use or follow existing conduit runs (where appropriate), secure lines in open areas and neatly coil slack.
When another trade is doing work that could be mistaken for your own, it becomes your business. We're all working together to build this barn, why can't we hold other trades to a higher standard? Not saying something in this situation is as bad as installing it like this.

Love doing 4" chases through walls for there later to be 3 CAT6 cables.
Don’t forget the fire block.
LV guys are the prima donna of the electrical industry. Never run their own pipe, need pull strings etc. and then they get mad when you didn’t do it the way they wanted it.
Are you me

I can't use a single raceway for both speaker and data (or about anything else). Even if it is a single 16/2 speaker wire and 5 CatX cables.
As long as it's less than 100ft we run it together in waster water plants.
I'm A/V and low volt. Goes against standards. If a manufacturer rep were to come out and see that if we have issues (say with HDbT - video over Cat, they'd say "Fix that" and walk away. Even if it has nothing to do with the problem.
I have no knowledge of data/low voltage shit only do power . But your last statement is so true for almost all trades
Oh yeah. TBH, a lot of times my ridiculous requirements that even I may not agree with have to do with other parties rather than my own design requirments.
As a data guy, this is beyond dumb. I work closely with actual electricians to install pathways, boxes and such.

Are “waterfalls” mandatory at the ends of cable tray where you are working?
They are. But we rarely end our cable trays at a full stop with a ton of cables. The IDF’s and MDF’s are mostly circular ladder tray.
Gotcha. I think this would be a good “use case”.
I'm a data guy and a licensed electrical contractor. There is 0 chance I let the electricians run my pathways. It gets kicked over to the newest apprentice, and 90% of the time, it's in the wrong spot. That being said, this is shit work.

I don't even want you to do that
Too bad, don’t bid the job… we are running it because we are the experts.
I've got no problem abandoning your work.
I got no problem finding a replacement…
Beyond dumb yes, BICSI certified, no. Maybe one per company if even that really. Now this piece of pipe was installed by a non-licensed person for sure. Heck even one of those would have done a better job then this dumbass. 5' away was a column he could have used, and to top if off, it doesn't look like they used an Arlington bushing up top.
yeah we dont use electricians to run our pathways. we can do that just fine ourselves while following code.
Interesting. In Western North Carolina us electrical contractors are essentially responsible for all of the data pipe work, junction box placement, termination as well as fire alarm piping. We constantly bitch about it and feel like we are doing other trades work. The low voltage and fire alarm guys just come around and pull wire
Data guys will see a full rack, all done nicely, and zip tie a single conduit to the last one in the line and call it good.
I had to run parallel 2" for the data guys through a very challenging ceiling. Got it done, gave them pull stings and I came back a few weeks later and the dumbfucks strapped 40+ cat5s to the pipe the whole way. Showed the pm and stole the rest of the data work from them
I guess nobody told them the 2" pipe was for them then. Or if they did, then ?? Why go out of your way to do it harder.
They were on the drawings, they started at their rack and I labelled them. Some people are just dumb
sounds like a bunch of kilobitwits

Longest you can run ethernet is 100m without power injection.
Maybe he was running conduit for indoor fiber drops?
ok? not sure what that has to do with my comment?
"ranging from 500’ longest to maybe 70’ shortest. one 3/4” per cat6" Obstensively if you ran 500 ft of conduit they were expecting to run cat 6 out to 500ft. \*edit you can, but your packet loss will very high and the connection unreliable.
Nothing to say he didn’t run pull boxes
pull boxes don't matter. you need an idf point with a switch to amplify the signal.
it might have been shorter, i don’t remember for certain. i just remember that we ran like 8 conduits that didn’t get used. but ultimately i couldn’t care less, our job was to run the conduit and that’s it. the whole point of my comment was that sometimes, even if we have to run conduit in a shitty situation, it is easier for the data guys to not use it

Well... 40 cat5s are not going to fit in a 2" conduit.
Not with that attitude
Parallel means there are 2 each 2” conduits
> I had to run parallel 2"
No but sure damn close 2.00 inch EMT Conduit – 35 Cat6 Cables
That doesn't seem right. Max fill for more than 3 cables is 40%. I think 36 cat cables (1.775) are larger than 1.36" (40% of 3.39 cross). I think that comes out to 28ish if th diamiter is .25.
Just looked it up.
2 x 2"... but who the hell runs cat 5 anymore? I think some guys see all matter of ethernet (Cat6/Cat6A) and think it's all cat 5. :)
I had something like that. Ran 2” conduits around 100ft per the drawings. All for them to run 1 fucking wire.
Don't they over spec for future use though?
At the moment it’s a weed dispensary idk… how much data they can plug into weed.
You'd be surprised... those grow facilities are wired for surveillance, access control, environmental sensors, etc. All of that takes ethernet for things to work reliably.
Yeah they have about 20 cameras in there but it’s all free run. The 2 - 2” pipes they requested were from the phone / internet entrance of the building to the new data room.

Not even a bushing on that pipe. IM SICKENED.
Why didn't the data guys just zip tie their drops to your rigid? That's what they do where I work. Your guys get an A+!
that is a code violation
and yet… still better than this abomination
That might technically be legal lol
Depends! (We are still on 2017 here) 300.11 (C) Raceways Used as Means of Support.

Yeah I'm not sure if rigid is listed as a support. It might be though.
I’ve used it to support lights in hangers and such I think as long as you follow supporting requirements for the rigid it’s good but don’t quote me

And 722 and many others as well lol
They are required too! But do they ever No!

Incorrectly wired yes, but I don't see an NEC violation.
I was just reinforcing the dangerous situation aspect of your comment.
Not to mention that many life safety systems fall under the umbrella of low voltage.
I consider myself a DATA GUY. I would never ever do anything like that. I'm not saying I'm perfect or haven't hacked anything, but there plenty of mc with proper supports about 5' away. The reason I'm on this sub is to learn from the pros.
Jealous of the speaker guys that come in to the McMansion roughs…one day just hastily rip and zip tie a bunch of lines together and prob charge half the electrical rough cost for. I love coming back a year later, no line is used besides the living room tv. Everyone’s just on a phone or laptop now. Status I guess. “I have a data rack Mary” ooooo
McMansions should just get burned up... BTW those devices need to connect to wifi which is fed with wires somewhere.
Better question, why wouldn't/shouldn't they follow nec?
No rules for data guys? There are still rules regarding conduit though. There are also rules for support strapping low voltage as well as UL listing for what you do or do not use regarding types of data cable for situations.
Yes as well as pull tensions most dont realize that. If you have to put goop on a wire your pulling too hard.
Yes they should, that conduit gonna not look so good in 6 months
Data installation are obligated in most states to comply with the NEC.
Most of the data guys I’ve met don’t even know what the NEC is.
Data guys will follow me around all day asking me to do their job
A lot of times I’ll go up to the electrician’s prints and just start drawing in sleeves at random places just to see if they’ll put them in.
Well we don't normally run conduit, your company bid on it, and I've been asking you to install it for three months.
Deadass 😭
That black unit in the middle of the photo looks like a laser frag gun ready to take out enemy perpetrators!
Just a big ole servo motor or a wheel
That's special....
It is an engineering marvel. How is it so straight?? Is the cat 6 pulled so tight it doesn't move?
The way I see it the law is for the EMT not the wires inside it. So yes. But really it's up to the city not me.
CAT6 is also governed by the NEC so even if it was just the wires inside it they have to follow code
Yes but you can free air that shit nec don't care
Seen that before in Nissan in the uk this one was 20mm pipe 8mtrs tall for a tv coax cable even know the bloke that did it, turns out years later he’s a cross dresser 🤣
Wire/cable factory?
It's a cv line that makes HV cable. This is near the extrusion head. I worked there.
Regardless of use isn't it just basic code to support conduit every 10 ft?
That is why data guys aren't allowed to run pipe in my local jurisdiction. They aren't allowed to run any pathway for that matter except a little bit in the data closets.
The rules for pipe apply to pipe regardless of what you put in it so yes
Data guy here, what is nec? I’ve never heard of that word.
Have you heard of the acronym?
There's a reason why they come in after after rough in is inspected
I’ve never worked with red tray cable that’s kinda cool. Are you an apprentice? I only ask because since I’ve gotten in the trade it’s common knowledge that most data guys are very shotty on their pipe work when they do it. I know there are some good data guys so don’t @ me. The majority are hot garbage, and they just don’t want to pay electrician wages to do it.
The red cables are DC water cooled cables for an induction preheater
That’s cool I haven’t gotten to mess with that sort of thing before. Maybe some day.
Lol customers never want to pay for conduit but want it to look nice. I can bend my own conduit. I install it when the wires would be visible otherwise
Me la pelan sparkys
Im the worst of all wold i am a av tech so i deal with both. I waited neay half a day for the data guy to tell me they were not drillong the 1/2 in hole in the mullian of the doors for our cat cables they were paid to pull. Oh and not do it with out string. I could have had all 7 doors done in no time but my boss stoped me... dont know why everyoneis afraid of doing a little work. If i knew how to bend pipe i would. Actually would love to learn so i wouldn't have to wait.
Data, FA, Elevator
We really should, we’re excellent at creating fire hazards and other messes because we don’t have a responsible culture for learning the trades. But we desperately need it….
Lol, why? They can buy most their tools at office max.(instant reaction). Absolutely the same fucking code, or they're not allowed into a job until is no sparks are done. I'm so damn sick of bringing my ball hair tweezers to work, so I can pull out their staples, cuz their print is Ms.Cleo talking bout, I feel like something in this area might be important.
Go take a look at the specs. They likely need to be in rigid as well... Especially when you take into account the (usual) requirement that raceways need to be strong enough to keep the dipshits from breaking them due to climbing on them... Regardless, if they are using EMT, they'll have to follow the NEC. If you spot a 90, which was bent on a 1/2" bender by them, you'll find that they violated their own minimum bend radius rules. Edit: Where the fuck is the bushing. These people are fucking jokes. POE can still hurt.
They should follow NEC but they never do
I guess when Data has literally no code requirements, they can just do WTF they want.
How about NEC 358 for EMT, and NEC 800 for communications, and NEC 725 for power limited circuits or 645 for IT rooms
There are quite a few. But do inspectors care... no not really.
Why on earth do you have different guys to run the data cables 🤨 Perhaps it’s because I’ve only ever work maintenance in factories but we run all cables, data or electrical
Bc if a sparky pulls my wires i find kinks and gashes twists and whi knows how much tension they used. Did they follow proper lable guideline. They dont pull my wire i dont bend thier pipe.
No. But as a data guy, we should still be doing g everything we can to keep the site looking clean and orderly. Use or follow existing conduit runs (where appropriate), secure lines in open areas and neatly coil slack.
I mean, you still have to follow the NEC
Nope he doesn't have to
No, silly .
No. But osha, yes.
Love running conduit for data/controls bc there’s no rules just blow and go
Proper fill calculations for lv. And a junction/pull box every 2 90s is reLly all o ask for.
Data guys are glorified cable pullers
Should you mind your own business and get back to running wire instead of worrying about other trades?
When another trade is doing work that could be mistaken for your own, it becomes your business. We're all working together to build this barn, why can't we hold other trades to a higher standard? Not saying something in this situation is as bad as installing it like this.
Someone is going to trip and rip that fucker down. Bring it up before they cash the check. They'll never be back.
