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.

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!

Went from "my dudes" to "my friends" to " my friend," next will be " to whom it may concern." lol

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!

1900 was the original part number for the 4" box sold by Bossert in the previous century.

Here in Michigan, we call the "1900 box" a four-square box. Four-square deep, or shallow for the different varieties.

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!!

This is so convenient ,i just got hired today and our company is working on a commercial site

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.

Dustin, please do more of these on commercial electrician work. Always enjoy your videos, thanks man!

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 appreciate these videos that take you back to the basics. 👍🏻

Sir, I just found this channel and I am beyond impressed. Thank you so much for sharing your knowledge and experience 🤙

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

Love your videos trying to get into electrical right now. Definitely teaching me alot.

The 'mc' in mc cable stands for 'metal clad'.

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.

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.

As and electrical estimator that was never in the field, I really appreciate your videos especially this one.

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!

Thank you, I have been wanting you to make a series of videos like this love the channel

Just came across your video - Amazing. Very informative. I am getting into the commercial electrical as well and this helps a lot. Stay safe.

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

Hell yea this is my first week in commercial electric, i needed this !

1900 was the original part number for the 4x4 box.

THANK YOU soooo much Dustin! You're awesome!!

This was awesome for starters man.

Man, god bless you for pouring your knowledge into us

Lovin' the Letterkenny big shoots!

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 guy is so good at explaining things.

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!!

Gonna get a hoodie for Christmas this guy is good at explaining, I've done that before...

Excellent video for people learning electrical work and Great UKposts channel Att (Rivera Electrical service LLC) from Puerto Rico 👍🏻

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!

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.

I’m a low voltage guy and absolutely needed this. Thank you ❤❤

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.

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.

👍👍up thank you bro for your time I really appreciate you teaching us your good information

Keep these comin, the more material vids the better

Good basic info, but we have some different lingo here haha! Good vids, keep em comin!

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.

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

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. 🤓

Awesome video, keep making more of these...

Try this use a 3/4 mud ring on 5/8 drywall best fit.

thank you sr. i have learn more from you than my actual super intendent.

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 😅🥳

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

In reality, those terms/ brands come out in the exams. Thanks Sir Dustin.

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

Awesome work thanks for Sharing

You gonna do PVC and fittings, also liquid tight and fittings. We do a lot of underground with PVC schedule 40 & 80

man, you are terrific. thanks for your videos

Thx for the info 👍🏻

Thanks for sharing, knowledge is power

Love this now to find the residential one

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!!!

This is such.a coincidence today i was running rmc in lab lol nice video

Yup! There’s way more but this was a great overview. Commercial rules!!

Thank you so much for this video it really help me out a lot

Currently in the HVAC trade but thinking about switching to electrical and working to get my masters and own my own business one day

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.

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'.....

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.

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

You are awesome! Thank you.

Thanks for the great video.

Usually called a 4 square box or 4 11/16 box but then depending where you are people call it differently

We test all of our employees on some of these parts! You've got to know!

Thank you!!!

I looked it up. They're called 1900 boxes because that was the original part number from the manufacturer Bossert.

Thanks!

Hey thanks! I'll be checking out the channel!

Great video! It’s good to go over the basics and also just to see what materials people are working with from region to region. Thanks 👍🏼

Great video. How about one on all the different emt clamps.

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.

Awesome videos man

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 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.

Very informative thank you, you didn't mention flex that has as a rubber coating what is it used for

I start my apprenticeship this Monday I’m excited I’m doing commercial

Thank you!

Really helpful tips. Hope the channel keeps growing.

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.

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

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 )

Thank you

Not to be a fly in the ointment, but there's PVC coated rigid conduit, called Rob Roy in the field. Also, threadless connectors can be gotten for type RMC conduit, so you're not threading it.

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.

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.

Something weird, my house is wired with EMT and 1900 boxes with mud rings. I don't know why that's code in my area, but it is. I honestly hate it because if I ever want to add an outlet or something, I have to run conduit and use octagon boxes or 1900 boxes! Plastic boxes and Romex isn't allowed here! There's even industrial covers in my basement where there isn't drywall! Something else that's weird is how they wired the house. There is one 15 amp circuit that supplies power to almost all the lights on the main floor, outlets in the living room, outdoor outlets, and lights in the back yard. That seems like a lot of devices for a single 15-amp circuit. Theres also a single outlet in the master bedroom that is on the same 20-amp circuit as the bathroom outlets. The rest are tied with the lights on a 15-amp circuit. If that's not weird enough, the garage outlet is on a 15-amp circuit with the outdoor lights and the laundry room lights. i don't understand why they used a 20-amp circuit for one outlet next to the breaker panel, but used a 15-amp circuit for the garage, where you have high-power tools! Not to mention, 2 separate bedrooms share a circuit, and the office shares the upstairs hallway circuit. Even my bathrooms all share one circuit for the outlets, and another for all the lights. TLDR: My house is wired weird!

In my area flexible metal conduit is called greenfield. I assume that was originally a brand name.

great help. Can you please make a video of the math that will need to be used? Thanks

You're doing fucking great. Never heard of 1900. Just a 4in sq to me lol. Ours has less syllables.

Been out of distribution since 2015 and this was a to down memory lane.

The 1900 box gets its name from it being part number 1900 from bossert.

It's amazing just how many companies manufacture Unistrut.
