COMMERCIAL ELECTRICAL MATERIALS Apprentice Electricians Should Know

[@gregorall9779]

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.

[@Son_scorpio]

That's true , I've got started in the trade I know some of them in different name .

You retired too early. Keep going :)

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!

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.

[@lukasvilla2657]

@@anhtuanestevez5427 hey how's it going? It's going well! I started off doing residential for a few months then I got an offer from a friend to do commercial work. I got a much bigger pay increase and I enjoy it more. It wasn't as hard as I thought it would be. They taught me alot and didn't throw me into the fire right away. I worked side by side with someone for a whole year and learned alot. Now I can do rough in, trims, install gear, bend pipe, pull wire, terminate panels, wire disconnects, etc. I also started at $14/hr in residential and as a 2nd year apprentice in commercial I currently make $21/hr which isn't bad for someone only doing it 2 years. Good luck!

I’m curious if the job worked out for you? Im a bit over 3 years in the trade and love it more then I ever thought was possible for a job. Next week I’m kinda getting thrown in the fire to show I’m capeable of being a lead in the future. My lead is gone all week for thanksgiving and I’ll be by myself 3 days roughing in a 4K sqft house. It’s about halfway done so still have a decent bit to go. Hopefully it goes well but I’m sure some dumb shit will happen. The homeowners/builder come with 400 change orders they want done ASAP.

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

[@docferringer]

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.

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.

[@edgerrr]

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

[@arthouston7361]

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'.....

[@firemayne]

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

[@arthouston7361]

@@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.

[@richt5986]

@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

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

[@Mr.Sparks.173]

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.

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.

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.

[@garbo8962]

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.

[@BudoThePaladin]

I'm only 3 years into the trade so far, but personally I prefer using the type of MC connectors that use a nut and tighten with two screws whenever possible over a snap in connector, they're easier to install. Edit: forgot to mention the 2nd part that's better is if you have a change order for whatever reason whether it's the location of a lighting changing or a desk's location, these types of MC connectors are also easier to remove when needed. Just better for the long term.

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!

1900 box was the part number for steal city in the early 1900s. Ita actually NOT CALLED A 1900 box anywhere but the east coast. That is a slang term. The correct term is 4 square deep or shallow.

[@GreatLakesDirtFishing]

I am baffled that 'four square boxes' are called anything other than that anywhere in the United States. I have heard some people call other electrical parts by their actually part number from the supply house. IE Circuit breakers, meter bases, etc.

[@santiagogarcia9436]

"Four square", "four square box" here in FL

[@marcelp7059]

Santiago Garcia never heard anyone call it anything other than 1900 in FL

4x4 where I live.

[@mos8541]

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

[@jameshaas5680]

This first company to make the 4x4 box at early turn of century. Its part no. For the box was 1900. It has carried through the century

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 )

[@LucasGresham610]

As a service electrician I prefer the locknut MC connectors as well.

[@jamesconklin120]

@@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

[@jamesconklin120]

@@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

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 👍🏼
