    4S box.

  2. Richard Sherman on August 25, 2021 at 9:49 pm

    Who is going to be making that can with the MC connectors?

  3. Tyler Amick on August 25, 2021 at 9:50 pm

    You forgot to add ground bushings or bonding bushings

  4. speed1984 on August 25, 2021 at 9:58 pm

    When I work with metall, I’m working on something from the 1980s or older.

  5. Ibrahim Mohamadi on August 25, 2021 at 10:01 pm

    Were these materials made in us or China?

  6. NH Entertainment Tv on August 25, 2021 at 10:01 pm

    Some people call a MC a BX

  7. Ivo VIM on August 25, 2021 at 10:03 pm

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

  8. Quinn Lessard on August 25, 2021 at 10:03 pm

    In Canada the first two are called 4×4’s and 4×4 duplex covers lol but I’m guessing the name 1900 comes from Iberville’s product number

  9. JCC Silverback on August 25, 2021 at 10:05 pm

    man, where were you 40 years ago? LOL

  10. Gerd Berg on August 25, 2021 at 10:05 pm

    So I think you give good explanations but , you need to be more thorough and careful in your use of terminology .
    It is not a big deal for us but very confusing for those that don’t have a full grasp of how the terminology is applied !!

  11. Modern Homestead on August 25, 2021 at 10:10 pm

    I’ve cled uni strut

  12. GoudaGames on August 25, 2021 at 10:10 pm

    Are commercial public buildings and apartment complexes in the US required to use halogen free cable against toxic gas released when heated like in Europe ?

  13. vandoo66 on August 25, 2021 at 10:11 pm

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

  14. Ron Rowhani on August 25, 2021 at 10:11 pm

    1900 box is called four square in California.

  15. Rachel East on August 25, 2021 at 10:13 pm

    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.

  16. Jay Cominos on August 25, 2021 at 10:14 pm

    Question for a guy that does not know. Not all residential items can be used in a commercial setting, can all commercial items be used in residential?

  17. tom on August 25, 2021 at 10:15 pm

    cut in boxes tried and true.

  18. WoodyDaAlien on August 25, 2021 at 10:16 pm

    Thank you!

  19. Nicholas Thon on August 25, 2021 at 10:17 pm

    Never heard it called a 1900, always a 4-square or 4-and-11 depending on size. I’ve only worked in the northwest, so maybe it’s regional.

  20. Gerd Berg on August 25, 2021 at 10:17 pm

    You need to call it what it is a 4×4 x 2 1/8 deep box.

  21. MikeL on August 25, 2021 at 10:17 pm

    Dont forget the pipe/wire stretcher

  22. John Doe on August 25, 2021 at 10:18 pm

    What is the proper name for any material? Whatever the manufacturer names it, they made it they can call it whatever they want. The supply house commonly change names to match local slang.

  23. john alt on August 25, 2021 at 10:19 pm

    HEY DUDE, YOU LOOK BETTER WITHOUT THE BEARD, SO SHAVE THAT FUZZ OFF. THE BEARD MAKES YOU LOOK OLDER LIKE RIP VAN WINKLE.

  24. Gregory Martinez on August 25, 2021 at 10:19 pm

    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

  25. Uriel Alva on August 25, 2021 at 10:21 pm

    Starting my apprenticeship next week any heads up ? It’s commercial

  26. Zfrenchy on August 25, 2021 at 10:21 pm

    I am not an electrician, just a fire alarm guy working with conduit sometime.

    6:42
    just one question, why blank cover has marking says "inside box side" ? For me both side look the same.

  27. tom on August 25, 2021 at 10:21 pm

    4 square

  28. Jeffrey Knowles on August 25, 2021 at 10:23 pm

    It’s a lock-nut, not a lock ring.

  29. tj e on August 25, 2021 at 10:25 pm

    Lol…please don’t actually "hide" any boxes

  30. Ray Oshima on August 25, 2021 at 10:26 pm

    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.

  31. Roy Tellason on August 25, 2021 at 10:27 pm

    I’m surprised that you didn’t touch on the plastic variants of a lot of this stuff…

  32. mike mac donald on August 25, 2021 at 10:29 pm

    man that 12×12 with the mc knockouts looks expensive ! won’t see too many that type

  33. Sir Nordeng on August 25, 2021 at 10:30 pm

    You hide your joints in that 1900 box??? You hand roll or pre rolled?

  34. Benjii Boutabag on August 25, 2021 at 10:31 pm

    Nice !’

  35. Gerd Berg on August 25, 2021 at 10:32 pm

    You called the relay electronic at first , You confuse sometimes

  36. 410_Redline street-team on August 25, 2021 at 10:33 pm

    Gangable box-aka the old work box.

  37. Karl Horton on August 25, 2021 at 10:33 pm

    Got curious …. This electrical box is usually called a 1900 Box because that was the original part number from Bossert almost a hundred years ago. From electricalslang.com

  38. Computer Rodeo LLC on August 25, 2021 at 10:36 pm

    You forgot about IMC ????

  39. charlesjcobb on August 25, 2021 at 10:37 pm

    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

  40. Wec19k on August 25, 2021 at 10:37 pm

    I’m an industrial millwright, not an electrician nor are my coworkers but we do some electrical work. We call a "1900 box" a junction box lol.

  41. Ben Gonzalez on August 25, 2021 at 10:38 pm

    Im an Electrican frm el paso tx. And a single gane utility box blank wit a knock out r known as chalupas here lol aka a canoe lol

  42. Paul Kronyak on August 25, 2021 at 10:38 pm

    That’s not a 1900 box that is a 4×4 deep box a “ 1900 “ box is 1-1/2” deep

  43. mos 8541 on August 25, 2021 at 10:38 pm

    so 1900 is what we call 4 square and the 2100 is the 4 11 or four eleven right?

  44. Mark Chidester on August 25, 2021 at 10:41 pm

    What is the difference between MC and BX?

  45. METALKILLSemosNpunks on August 25, 2021 at 10:42 pm

    This is pretty much all we use in NYC. Whether it’s skyscraper or a townhouse.

  46. Adjahni Thermot on August 25, 2021 at 10:43 pm

    Can MC cable be used in residential or does it depend on local jurisdiction?

  47. Chris H on August 25, 2021 at 10:43 pm

    IMC conduit is stupid

  48. Travis McDonald on August 25, 2021 at 10:45 pm

    I work mostly in refineries. We use a bunch of strut and spring nuts. Most of the time we rip the spring off the spring nut.

  49. james conklin on August 25, 2021 at 10:45 pm

    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 )

  50. Alex on August 25, 2021 at 10:46 pm

    In Canada we call those boxes 4x4s
