I'm retired now after 35 years in the trade, but something that I learned early on is depending where or who you're working for, you're going to hear all of these items referred to by different names. Great video for the individual just getting into the commercial side of the trade and a portion of them being used in industrial. Remember, it's not a competition to see who's better, we're all in the same trade so instead of tearing each other down, build each other up.
That's true , I've got started in the trade I know some of them in different name .
You retired too early. Keep going :)
@venividivici4253 I'm enjoying my new job of being retired way too much!! If I had known it was going to be this fun, I would've done this earlier.
Your cool asf
Amen brother
Went from "my dudes" to "my friends" to " my friend," next will be " to whom it may concern." lol
Lol
Nice one

Hi Dustin. This is Bill from Sparky Channel. I want to sincerely thank you for mentioning the new Sparky Channel on one of your videos/instagram. For those who don't know, the original Sparky Channel got hacked and the hacker deleted my 934 videos and I lost my 182K subscribers. I have started a new Sparky Channel which now has 62 videos and 2600 subscribers. Some of the new Sparky Channel subscribers came from your channel after your announcement so I want to really thank you for that! Best wishes!
Sparky Channel I haven’t seen anything recently by you but I thought it was because I only subscribed in my other account. Between the two of you I learn most of my electrical. 👍 Sorry for your hack, and resubed. ✅
Bill, thanks for the info. I was wondering where all the sparky channel videos went.
What? That's horrible... No wonder your videos have disappeared from my KZhead recommendations. MAKE A SUPER TOUGH PASSWORD!!!!!
New subscriber sparky
wow sparky, very impressed with your video out put and quality. I feel so awful for you about your channel. I hope you can someday recover from that.
Not sure why you decided to start doing these videos but I’m very grateful. As a visual learner it took months for this stuff to click reading about it but going through these videos cuts that process tremendously. Keep up the great content!
Here in Michigan, we call the "1900 box" a four-square box. Four-square deep, or shallow for the different varieties.
4 square deep, 4 square shallow
It’s called a 4x4 where I’m at
Yeah 4x4 where I'm at, and I'm assuming when he says 2100 box hes talking about the 4x4'11 boxes
Same here in FL
4 square, 4x4
1900 was the original part number for the 4" box sold by Bossert in the previous century.
Thanks for that bit of trivia! I was expecting it to be the size in cubic millimeters since the metric system has been creeping in everywhere. Close, but no cigar: 1900mm = 74.8 inches vs. 4" x4 "x4" = 64 inches.
That’s interesting. When I was in the field, we never referred to them as a 1900 or 2100. I moved to another state and realized how different the nomenclature is area to area.
In NH I never heard either term in 38 years
@@gerdberg4188 made it to Mt Washington a few months ago. That’s a pretty area up there
I didn't know the company, but I did know it was a product number
Tomorrow is my first day with an electrical company. I'm super nervous. I've never done this kind of work. They said I will be doing pre-fab for 6 months to a year then I will be out in the field doing 3 phase work. The cool thing is they are paying for my apprenticeship school after I'm there 60 days. I bought a bunch of tools yesterday from harbor freight because that's all I can afford. I subbed to your channel. Good information! Thanks. I'm going to just take it day by day and not get too ahead of myself. I will learn as I go.
I really like your videos, in particular these two about the different devices and connectors. I am a Electrical Department supervisor at a Home Depot, and trying to be more knowledgeable about the products that my customers need to buy. Keep up the great work and thanks again from a different sort of industry professional!!
The 'mc' in mc cable stands for 'metal clad'.
This is so convenient ,i just got hired today and our company is working on a commercial site
Nice one
Tom Garbo Thanks,i’m still in trade school so i’m gonna make all the mistakes i can while i’m still in school.My boss told me that Florida doesn’t have a lot of industrial sites,so we’re not gonna he bending much pipe at all but it’s still good to learn it.Since i’m the youngest guy at the job (18) he told me to expect to get teased a lot by the older guys Lol
Ummm. U sweep the jobsite. This wont help
Tom Garbo i got financial aid so i used that to buy a code book.I also purchased an UGLYs book last week.Ill definitely keep that in mind about the harness Lol
You'll be carrying alot of conduit and alot of item chasing lol
Hell yea this is my first week in commercial electric, i needed this !
iver been apprentice for shit...damn near umm 6 weeks!
Congrats! I've been an apprentice seven months so far, how's the trade treating you?
@B M fine i guess, been in 3 Unions as a young man im 55, havent been in one since i left IL in 2002, one of my unions was taken over by the Justice dept. it was so corrupt, no man should be Forced, to Pay or Join ANY organization...JUST to work..
@@Bonavire well i got very Lucky...finally i guess, im prob too old, but i do like it a lot , SO much to learn and always punch out having DONE something, etc.
Dustin, please do more of these on commercial electrician work. Always enjoy your videos, thanks man!
Sir, I just found this channel and I am beyond impressed. Thank you so much for sharing your knowledge and experience 🤙
1900 was the original part number for the 4x4 box.
Good
I love your content by the way. I was just given my first apprentice, and I told him to check out your videos in his spare time!
I have like nearly 2-3 years experience (as a helper) but its very scattered with a lot of different contractors so your videos are a huge help. Nice to catch up on stuff I have not touched in 6 months! Greatly appreciated, thanks! In NYC its either you attempt to try to get into a union which takes years or you try your luck working for private companies that sometimes do not even hold an electrical license under their name.... Lets just say credible info is scattered -- thats if you even get coworkers that speak english.
Isn't this the truth. I've been doing this for almost 20 years, & i do work in the boro's but mostly on Long Island, & it's pretty much the same thing.
No lies detected here
Dope hat!! I work in commercial but I do EMS, low voltage controls for grocery remodels but I deal a lot with these materials. I have to pend pipe and your videos are amazing. Appreciate what you do
I’m just getting into it. Thank you for the help. I’m taking my own notes but videos like these are great for newcomers and those who would like quick refreshers.
Love your videos trying to get into electrical right now. Definitely teaching me alot.
Would love another video of this as you could def cover Conduit Bodies and anything else you missed like wire pulling materials like bird cages, baskets, fingers, bullets, sister hooks, etc! Great video!
yes please
I appreciate these videos that take you back to the basics. 👍🏻
I love how comprehensive this video is!
Thank you for explaining and teaching us about these commercial materials. This coming Monday is my first day of work in commercial electricity and I found this very helpful. !! Keep up the good work!!
How did it go!??? I also start in a few days and I am excited!
Hey Dustin I hope you pick up the video grind again soon I’d love to see some of your day like even if you wore a go pro and recorded your day or your most annoying things you come across. I’m an apprentice 6 month’s in and I enjoy your content and wanna see more day by day struggles like how you would solve getting a wire around a corner when roughing or stripped screws stuff that happens but not often and cause a big struggle for you. It’ll give me some experience or tips on my own day to day. Much love keep up the good work my dude
I’m an apprentice in NYC so according to code here we literally only use these kind of commercial materials on everything including residential and never use romex or plastic boxes so it’s just interesting to see that my daily use materials is other people’s commercial only materials. Great video tho thanks a lot!
I’m a low voltage guy and absolutely needed this. Thank you ❤❤
Thank you, I have been wanting you to make a series of videos like this love the channel
Good
Lovin' the Letterkenny big shoots!
Just came across your video - Amazing. Very informative. I am getting into the commercial electrical as well and this helps a lot. Stay safe.
Gonna get a hoodie for Christmas this guy is good at explaining, I've done that before...
As and electrical estimator that was never in the field, I really appreciate your videos especially this one.
There are videos that make you feel compelled to "subscribe, like, and save". I am an electrician, without a license, but I work 100% for the NEC which I also love. Thanks for the Spanish translation, (I think it was you) .. thanks for the video. Subscribed.
This was awesome for starters man.
THANK YOU soooo much Dustin! You're awesome!!
Next size up from 1900 is the 11-B. There's also an 8-B which before I learned what it was I called it an octobox. Spring nuts can be ordered without a spring. They are called strut nuts.
8:00 That box looks very busy. We use the grey boxes with the 5/8 inch and 3/4 knockouts for bx and 3/4 pipe. Anything bigger and you can use a knockout for larger sizes. You probably won't have that many pipes or bx collecting in one box. Unless it's a pull box around a panel.
This guy is so good at explaining things.
Hi Dustin, not sure if you have already but I could not find a video on single phase vs 3 phase. Thank you. Keep up the great work!!!
Adolfo DiBiasio hire a professional.
Excellent video for people learning electrical work and Great KZhead channel Att (Rivera Electrical service LLC) from Puerto Rico 👍🏻
Great video! Thanks for another Great one!
Thanks. I am an engineer who works in maintenance of PLCs and such, and get tossed facilities electrical work sometimes and just have to go thru piles of random electrical to figure out what to use, now I have a better idea.
Important note about contactors: the ones used in HVAC equipment are "definite purpose" contactors. You CANNOT use them for a different purpose, such as controlling lighting in a store. Contactors for lighting are MUCH more expensive, and are listed and approved for the purpose. Definite purpose contactors have a definite purpose that is NOT lighting a store. Make sure that any contactor you install is listed for the purpose. I'm just sayin'.....
4 inch square memphis tn
You could use any contact anywhere as long as the amps is what is rated for the contactor.
I do lighting controls with contactors that are only meant for 12 V and I have other lighting contactors That are rated for 2hundred amps at 480v
@@richt5986 Actually, no, it is against the national electrical code to use anything except an approved contactor for lighting. You cannot use an HVAC “definite purpose contactor,” which is why I mentioned that. The difference in cost between a definite purpose contactor and one that is listed for use as a lighting contactor is about 10 times.
@Art Houston sorry not the point. I may have not explained better. You can use any contactor for whatever as long as it is rated correctly by the amps and volts
The gangable boxes are a pain, but they are a hell of a lot more durable than the blue plastic boxes that flip around in the wall. That romex is “acceptable” in houses, barely. I don’t think the rodents in our area have learned that 120VAC is a bad thing to eat, fair number of plastic chews.
Awesome video, keep making more of these...
Man, god bless you for pouring your knowledge into us
👍👍up thank you bro for your time I really appreciate you teaching us your good information
Awesome work thanks for Sharing
Try this use a 3/4 mud ring on 5/8 drywall best fit.
it's called a 1900 box because back in the day it's catalog number was 1900. At least that's the story here in Chicago. As far as those other materials, the trade names here are so different that I just had to turn the video off because I didn't want to confuse them.
That's what I've heard too.
We test all of our employees on some of these parts! You've got to know!
I been working in this company for around 2 months and your equipment look way better than what I’m using. Like those single connectors and doble gang connectors I’ve never seen
Good basic info, but we have some different lingo here haha! Good vids, keep em comin!
Could you maybe do a video about magnetic and manual motor starters with ladder diagrams? I’m doing motor controls in school and having a hard time understand ladder diagrams for motor starts. Like how do you figure out where auxiliary contacts, overload contacts ect are on diagrams and motor starters. Love your content man. Thanks.
jared thompson KZheadr "Watch Wes Work" video called "CNC Machine Stuck in Emergency Stop" will help you out.
For those north of the border. 4x4 box, Bullnose receptacle cover (decora/standard), mud ring, steel stud box, gang box (device box), different from a cut in box, L16/Twins, AC90 (where is the spool?), Connector/coupling/liquid(or concrete tight), 4x4 blank cover, 12x12 JB (would never need a box that big for residential, useless in commercial), relay, contactor, spring nuts/spring nuts that someone broke the spring off, unistrut (deep/shallow), EMT/Rigid Conduit, Flex
Great video. How about one on all the different emt clamps.
You gonna do PVC and fittings, also liquid tight and fittings. We do a lot of underground with PVC schedule 40 & 80
Keep these comin, the more material vids the better
1:21 in my experience, city, county and state, hiding a junction box is against code. I know that's not what he meant, but some people might take that wrong
In Canada a junction box just needs to remain accessible. As long as an electrician can get to it and service them, its good. That means hiding them in an attic or crawlspace is a-ok by code. Same with tucking them up into drop ceilings.
Yup! There’s way more but this was a great overview. Commercial rules!!
man, you are terrific. thanks for your videos
My favorite part of doing switches is when you discover at the final that one of your lovely coworkers has tied in the wrong switch legs at the rough-in stage. Not just tied into the power pigtail... No.. Tied-in to the wrong 2gang switch box entirely 😅 (side by side in the wall but in different rooms 👍) Not *that* hard to fix... But.... Yeah 😅🥳
Thank you so much for this video it really help me out a lot
As someone who is going to be running the MC cable (but not connecting to the fuse box) throughout my place, I appreciate your videos; thank you! Due to our location, companies demand huge money, and many use interns to run the cabling at $150/hr! Of course, the interns stop watches videos, plays games, questioning everything, calling friends, etc. and I refuse to pay $10,000 to run MC cable! This helps me understand the lingo better, especially when ordering or talking with my inspector. Don't worry interns, there is still enough work for you in the future, and growth isn't stopping any time soon.
wtf I get paid $22/hr to run MC
@@Bapuji42 are you an intern or electrician?
@@inve lol apprentice obviously What's an intern?
@@Bapuji42 haha, right! Sorry about that. It’s common practice for companies/firms to bill there apprentices and interns out at near full rates. Law firms do this all the time, so do plumbing and electrical companies. Sad they don’t pay you more, considering what they charge.
I remember watching this video shortly before I started my first job in electrical (didn’t know what any of them did) and then a couple months in (had a good idea what most of them did), and now 18 months in I can say that I am familiar with everyone of these materials. 🤓
thank you sr. i have learn more from you than my actual super intendent.
You are awesome! Thank you.
This electrical box is usually called a 1900 Box because that was the original part number from Bossert almost a hundred years ago. It is the most common box used when a simple SwitchBox is not large enough.
Hey bro just wanted to tell you thank you I'm going to print using as an electrician right now and I'm starting out my first year for your schooling and I found your channel and I'm hooked I appreciate you taking the time and effort to explain things I catch a lot of crazy looks on the job because I don't know certain types of connectors and boxes and everything and I'm learning 😂I appreciate u bro 🤙@electrician u
Thx for the info 👍🏻
Awesome videos man
Thanks for the great video.
This is such.a coincidence today i was running rmc in lab lol nice video
Another name that some people call flex by is “greenfield” especially in and around Chicago area.
Another thing is people might call the industrial covers “garvins”
It's greenfield on the east coast too.
it's greenfield if it has no wire in it. MC has wire in it.
Thanks for sharing, knowledge is power
I looked it up. They're called 1900 boxes because that was the original part number from the manufacturer Bossert.
Thank you!!!
Love this now to find the residential one
Started working in the shop so I have to know every single part. I’m putting together foreman’s lists for different jobs and dropping them off. It’s pretty cool. I’ll be getting in eventually as well.
stockman?
@@adrians.1154 material handler. same shit.
@@Alex-jo2oi nice, im about to start as one, any tips?
@@adrians.1154 stay on point write everything down and keep a list of the break times. Don’t ask the same question more than once. Don’t show up on their lunch or break. If you have stops to go to don’t mess around until at least after you drop everything off. Ask questions about the jobs and be interested. Learn as much of the material as you can. Show them you’re serious about the job and don’t be arrogant. Put your ego to the side. Embrace the dumb things you might do and learn from it.
@@adrians.1154 almost forgot an important one. Take initiative and don’t wait for them to tell you what to do.
Currently in the HVAC trade but thinking about switching to electrical and working to get my masters and own my own business one day
Hey thanks! I'll be checking out the channel!
In reality, those terms/ brands come out in the exams. Thanks Sir Dustin.
Good video! Anyone know If M/C CABLE can be used in cellulose insulation? Not sure if it can harm the casing. Having trouble finding info on this!
In my area flexible metal conduit is called greenfield. I assume that was originally a brand name.
That's what I learned it as, too. And the weatherproof or Raintite, as Dutin referred to it as was called Sealtite.
Really helpful tips. Hope the channel keeps growing.
Usually called a 4 square box or 4 11/16 box but then depending where you are people call it differently
great help. Can you please make a video of the math that will need to be used? Thanks
This is pretty much all we use in NYC. Whether it’s skyscraper or a townhouse.
same near the Chicago area.
Not to take anything away from you brother your awesome this is just for the apprentices. I'm a 9 yr commercial journeyman electrician out of San Antonio Tx. Great video I watch all your content, The 1900 boxes or 2100 refer to cubic inches in the code book, used for the calculation of the box fill.
المحتوى الخاص بك جميل - لقد استفدت كثيرا أخطط للبدأ في العمل ككهربائي شكرا
Been in the commercial field for the past 25 plus years , recently been working in Hospitals and medical buildings , the company I’m with now uses most of the material you mentioned , except the snap in connectors , we use the locknutables 🤪 , better to use when you fish mc cable down a wall and install a cut in box , Also the mc cable in hospitals has to be Hospital Grade ( FYI , industrial covers is also called raised covers )
As a service electrician I prefer the locknut MC connectors as well.
@@LucasGresham610 well we know how bulky those locknutable connectors are especially if you fishing down a wall into a 4”sq box that already has a snap in double barrel connector in it 🤦♂️ A lot twisting involved, not a fun fishing trip
Thinking about dropping hvac school and going to commercial electrician, mind if I ask how much u make? I’m trying to get a feel for what pays most
@@mistanipples4958 It Depends on where you live , and what kind of commercial work , you could get on with a company doing government contracts and make bookoo bucks or get in a union
In Canada the first two are called 4x4’s and 4x4 duplex covers lol but I’m guessing the name 1900 comes from Iberville’s product number
Maybe it’s just AZ but I have NEVER heard of a 1900 box. We call them 4S boxes here lol.
Great Review.
Here in the East we all call MC cable, BX cable. When it was being developed, there several versions being tested. A experimental, B experimental, C......., their names were shortend to AX, BX, CX..... The Bx won out and the name stuck. So, around here that's what we all call it. We call armor jacket (bx with no wire) , Greenfield. But that's another story
It's amazing just how many companies manufacture Unistrut.
Yes, and how many different materials/finishes they are available in.
Been out of distribution since 2015 and this was a to down memory lane.
Thank you!
In nyc we use all those commercial grade material in residential high rises
Thanks!
For commercial work always purchased panels & junction boxes without KO'S so I could make KO'S to line up with handy unistrut saving an offset . Also used steel EMT fittings instead of POS garbage die cast fittings.Have to be careful with handy gangable wall cases. Boxes from different manufacturers often will not gang together. Love the 12 by 12" JB with built in MC connectors & ground bar. If you are going to connect a critical motor or motor that will turn on & off more then say 30 times a hour best to go with a made in USA NEMA full size real deal starter ( Square D & Allen Bradley ) starter rather then inferior IEC contactors which most will not allow you to replace contacts.Flex = greenfield.
