How Does an Electrical Service Work? Electrical Service Panels Explained
Вставка
- Опубліковано 22 чер 2024
- The term “Electrical Service” can be confusing for many electricians. What does it consist of? Why are there different sizes? Why do we have overhead and underground services? Where does the service start/stop and where does the building power take over? In the latest episode of Electrician U, Dustin answers several of these questions surrounding the topic.

In the simplest terminology, the electrical service is the point at which power from the utility enters the residence/structure. Usually this takes the form of a utility transformer, which steps down the power to something we can use (say 120/208v or 277/480v). That transformer consists of a primary side (coming from the power generating station) and the secondary side (that which is at a much lower voltage) going to the building itself. As with all electrical circuits, each side of the transformer consists of a complete loop (or circuit) that allows the flow of electrons to return to its source. Different sizes of loads require different sizes of services. A house for example, since it is not large in size, will have a service from 125a to 200a, while a commercial building can have a service up in the thousands of amps depending on the size of the building and what’s being powered. Something to consider is the ground. Electrical services do not have a grounding conductor with them (normally). We derive the ground at the point of utilization. In other words, once the utility has brought power TO the structure, THEN we bond our neutral point to the earth so that a safe alternate grounding path is available for the circuit to return to its source and trip a breaker or blow a fuse. Most utility companies will disperse their power in three phase, dropping two of them off to be used at single phase installation (like a residence or smaller commercial space) and using all three phases at the larger commercial/industrial applications. Most residential power circuits do not require three phase to operate, so the utility doesn’t typically send three phase to residential neighborhoods. The commercial/industrial installations require three phase to be more efficient with all of the different items needed to make the building operate- lights, large and small motors, receptacles, equipment, etc.
When it comes to grounding the system, there are 3 basic items to remember. The Grounding Electrode is the item used to connect the system to Earth- like a ground rod, or grounding plate, or Ufer ground. The Grounding Electrode Conductor physically connects the Grounding Electrode to the system, usually in the form of a wire. Without it, the system would have no way of being connected to the earth. The Equipment Grounding Conductor is what we would normally associate with the ground wire connecting our electrical equipment together. It is meant to bond all of our equipment together and leave everything with a safe alternate path of grounding.
Overhead and underground services are available, and you will see both used frequently. While newer installations will put the service underground, the older ones you normally see overhead. Aesthetically, it is much more pleasing to the eye not having to see the overhead wires and poles, and technology/equipment have become much better in the recent era to allow us to dig them in. The meter itself is also considered part of the electrical service as this is where the utility can measure the amount of electricity being used and charge accordingly.

I’ve been an electrician for a long time and the question I would like to see answered is how electric produces the energy without any loss of mass in the circuit.
Energy is not produced. It changes states and electrons move. Nothing is created or destroyed. Mechanical energy or solar pv is converted to electrical energy. Then changed back into whatever form the load is. If the load is a heater, the heater is not destroying electrons to produce heat, it is changing electrical energy into heat, another form of energy.
@@jeremiahemswiler4540 I knew that electrons weren’t consumed the strong force being what holds them in place. I remembered that a volt is defined as the force that it takes to (push ) one amp through one ohm of resistance. The others are defined in the same manner relative to each other. So I guess then my question would be do we have an understanding as to why current flows through a conductor if it moves through a magnetic field?
Ive been an Eletrican for 28+ years an if that ole poor boy wasn't lost he sure the He'll is now lmao
@@jefflenway4510 I got my masters in 1988 and I’m not lost. What he’s basically saying is that power is obtained not from the electrons in the circuit but from the electromagnetic field in the circuit. My question then would be do we have a good understanding of the force that causes electrons to move back and forth when a conductor is moved through a magnetic field at an angle? I realize that this is really more of a physics question since electromagnetism is a fundamental force. Still important to know as far as theory goes. If a magnet collects energy since there is no conversion how well do we know that process.
@@deweyplanck9850 You might be meaning your question in a deeper perspective but it would be the electric field. I suppose it's like a chicken and egg question since you have capacitance and inductance that have inverse characteristics but if you have the voltage you have the electric field. So if the circuit can close any kind of way where you have the current flow then you have the magnetic field as well as electric field. The conductor has been aptly named rather than some kind of generator since it is just a conveyor of charge that contains a ton of electrons so in a basic water pipe analogy the water pipes only lose Mass over time through corrosion etc. I suppose another way to frame your question more generally would be asking whether electron theory is entirely accurate and I'm far from knowing the answer to that.
I've worked in construction for years, though not as a laborer, and it's incredibly challenging to find simple explanations of how things work if you don't become an apprentice or go to trade school. You're doing an incredibly valuable thing here by explaining this stuff in plain language.
I studied house wiring in high school and I struggled but being an electrician (Journeyman) is my dream job. I have a learning disability so I don’t learn things as fast. I’m currently working as a panel assembler. I’m trying to work my way up to custom for right now and then go back into the trade. I know the IBEW does an apprenticeship but can other companies offer an apprenticeship? Do they take people who have learning disabilities?
@@yt-kingdavid2359 how does it work
@@jeremynguyen2346 how does what work?
@@yt-kingdavid2359 electrical service how does electrical service work
@@jeremynguyen2346 I’m not sure. I watched the video for that reason. When I was learning about service entry though for house wiring, our job was to only bring it into the panel and wire it. Outside of that is a whole other field of work. Obviously higher pay. An example company is Met-ED. That is our electrical company near us
I have never been so intrigued by electricity until I became a homeowner. I used to perform receptacle and switch change outs while working with my dad but all I would do was remove and replace never thinking or knowing if it was wired correctly. Thanks to Dustin, I have received the right amount of education that has opened my eyes and give more respect to the trademen/women who make it happen so that we can live comfortably. Thanks, keep these videos coming...
Here in the Midwest we have to deal with tornadoes and crazy storms, but not earthquakes. Falling trees have ripped services apart. I've seen cases where the whole breaker panel and meter have gotten ripped off the walls. So our AHJ and power company force us to go underground for all new and rebuilt residential services.
The major cities have adopted service laterals over service drops for safety and to reduce clutter.
In some areas, particularly where tornado's are plentiful, underground makes sense. In other areas, I have seen power companies fight underground tooth and nail, even threatening to leave an area if they are forced to go underground. Thanks to Dell, I spent a year in Oklahoma City, including a storm in which I as a trained spotter was looking for a place to hide, only to find all of my neighbors outside in the driveway pointing at the tornado headed for them.
Great explanation! Regarding overhead vs. underground - In MN it's getting more and more rare to find overhead lines to buildings, or even within a town. We consider that mostly more reliable. In our part of the country it's very, very rare to have disruptions because of weather. Farms still tend to be overhead, but residential service is underground, and we don't worry about high wind, ice storms, tornadoes, etc. taking out the power. Local power companies are finding it saves them money, especially for repairs.
and he forgot to mention hoodlum's cant screw with it as easy as things like a kite doesn't end up in the powerlines ect. and a car wreck is less likely to nock out power as there is no poles to hit every 100ft or so
When I was a kid a mole decided to eat the forbidden spaghetti and electrocuted itself. We didn't have power for a couple of days until the power company dug up the line and figured out what happened
@@bobby_greene was it in pvc S40 or 80?
I would love a video on how to calculate the electrical load of a service using both the standard and optional methods. Also how to properly use a clamp multimeter to read all phases and how accurate this option is. When trying to determine if someone needs to upgrade their electrical service what is the best and most accurate method to use? Thank you and love your channel!
As someone who got laid off 6 months ago, having worked as a Commercial Electrical Apprentice for the last 4.5 years, your videos are entertaining as always and factually accurate as well. Thanks for the great content.
@PickleRick7571 lol. I'm not some chump. I had some personal reasons as to why I couldn't finish school. School was the least of my worries. I work hard and do good work. I apply myself in anything and everything that I do. The reason for my lay off might've had to do with me but I think there was more going on behind the scenes that I'm not aware of
Thanks for your videos. You are a natural teacher. I came across your channel two months ago while I was studying for my ETCP Entertainment Exam (concerts, theatres, events). In the exam the had code questions which is not something I was really shown in the past. We mostly deal with NEC 520/530, I found myself watching a lot of your videos to really understand the basics or the building blocks. It’s made me understand it all much better. One thing I haven’t seen you cover is harmonics. This was a topic that was stressed during my exam prep. While I understand the concept enough to get by, I’d love to see more in-depth explanation and some examples.
I’m not an electrician. I got interested in this while reading about about electrical charging for a vehicles. This was REALLY helpful.
Much more concise, love how quickly you've integrated feedback and corrected mistake in same diagram used in the last video. This video was pretty much perfect.
I'm 9 months into my pre-employment Electrical program through IBEW in Manitoba Canada. Just want to say that I'm so grateful to have discovered your channel. I'm sure you get this a lot, but the work and effort you have put into this is just incredible and definitely surpasses the lectures I'm getting in class in terms of both quality and information communicated. I've subscribed and I have a feeling I will be watching your videos for years to come as I work through my apprenticeship. Thank you so much :)
Thanks for this vid bro!. I’m a Local 1 NYC plumber. You’ve answered questions I was ashamed to ask my local 3 bros. Salute.
Great video Dustin! I am going to share this!
Maybe a future clip can go into UFER’s? On new additions or new construction. Are they allowed everywhere? Are grounding rods better? Thanks for all the info. I didn’t know that the main breaker meant for each bus but now it makes perfect sense. Thanks for that knowledge as well.
Back in 2001, I installed on a Single Dwelling Residence a 350 Amp 120/240 VAC Single Phase RT / WR Meter Base with a 120/240 VAC 200 Amp RT/WR Disconnect Panel next to it with '' feed thru lugs'' to feed power to the Square D Homeline Main 120/240 VAC 200 Amp Panel in the House and also to feed 120/240 VAC 200 Amp service to a 50' x 100 ' prefab Metal Shop Building about 75' from the house. The Shop Building has a 120/240 VAC 200 Amp Square D Homeline Main Panel which feeds power to a 120/240 VAC 60 Amp Sub Panel (#1) in one part of the shop, and one 120/240 VAC 60 Amp Sub Panel (#2) in the Machine Shop and another 120/240 VAC 125 Amp Sub Panel (#3) in the Machine Shop also for Welders and other machines in the machine shop, such as a 240 VAC 25 Amp Single Phase Metal Lathe, a 240 VAC 30 Amp Single Phase Industrial Band Saw, a Single Phase 240 Volt Drill Press , a Industrial 240 VAC 30 Amp 3 Phase Milling Machine with a Phase Converter (from 3 Phase to Single Phase) with a 5hp 240 VAC 20 Amp Single Phase Motor. The Service from the Power Company (OnCor) Power Pole mounted Transformer to the house was a underground , a '' lateral '' in 4 '' PVC Conduit and the service to the shop building was also an underground lateral service installed in 2 '' PVC Conduit. All Conductors were Copper. The middle part of the shop is the Woodworking Cabinet Making Shop and it has yet to be completed in regards to the electrical rough in for the required outlets for the table saw, Drill Press, Wood Lathe, Sanders, etc; I also installed all of the Lighting fixtures for the entire building , all done with 4' four lamp LED low profile types fixtures mounted to the overhead purlins all done with 1/2 '' EMT and also installed 6 commercial type ceiling fans in the building for air circulation during the warm summer months .
Sounds like here, on our farm. Feed through for house and main run to barn and... beyond. 👍
Congrats on your career and your channel, man. Really glad this stuff is out here & can't wait to throw some support. You're great at breaking things down in a way that's easy to understand. Inspiring stuff!
I've worked as a shipyard electrician for a decade--really without proper schooling, just winging it--and these lectures are really humbling. If nothing else they show me to be more careful, ask questions, don't just jump in. The least little bit of slop, like lightly nicking a conductor or tightening down on insulation instead of only the conductor, etc. can lead to grief down the line. I am chastened and will really watch it from now on. Thanks a load to all of you making these videos. You all really know your @$#%!
I love the way you articulate the topics in your videos. I’ve been watching several of your videos in the past week and all of them are very well done. I especially enjoyed your three and four way switch video. Thanks for the great content!
Excellent video, Dustin. Keep em coming. Last year when I was running the Cat 6 cables in a newly built 3 story apartment complex in Charlotte, NC as a subcontractor, I saw a lot of larger apartment complexs with a very large disconnect, sometimes one on each end of the building, that was labeled like "1200 amps, 208Y/120 volts, 3ø" then of course each unit inside would get 208/120 volt single phase while the elevator and main HVAC system would run 208 3 phase with or without a neutral
As it would be extremely uncommon for 3 phase to be found in a residential situation, unless there was a home workshop where the homeowner is running his own woodworking business and had a bunch of heavy duty air compressors and lathes that requires 3 phase, or it was a custom built luxury home that is exceptionally large, and the utility company would allow it.
my suburban aera's had it 3P intel about the mid 1990's as my 1950-70's subdivision was the pathway for the main city step down T's/lines 240v/120v 😉 sp but they change it to put more houses in under where the poles/equipment where ect. and had i had the chance id have liked to had kept it but in didn't move into this house intel after 2006
"Richard Price I've heard of certain places in the country, notably Arizona and Texas areas, in the 50s and 60s, some larger homes had 120/240 3ø 4W delta service. As I'm told, when central air c..." . um what happened to you reply? and i thing 🤔 are's was a delta configuration 3 or 4 wire id have to ask down the road from me as he is still running the same equipment but changed/modified for 400A SP 240V service in a 3k-4k sqft home as my newer setup my older one was single phase as well but i don't know if that is from the occupancy tax disk aka new or not
Excellent video. I passed it to my apprentice electrician class.
This is great for anyone trying to get a basic comprehension of 3 and single phase service entrances!
Well done!
Excellent video! How about a video on cautionary tales regarding “power strips”? Overloaded power strips, plugged into a 15 amp outlet, cause many house fires
I tracked a powerstrip that was back feeding a whole phase onto the ground buss. Like phase to ground read 208 and ground to neutral read 120, the the affected phase to ground read 0. It was f@cked. I found outlets with 208 etc. Still dont understand why it didn't cause a ground fault.
@@Makitafan It sounds like the neutral and ground weren't bonded at the service. The earth ground, grounding electrode conductor, does not always provide a path with little enough resistance to generate enough ampacity to trip breakers. The neutral is the return path that allows the breaker to function under that condition. Also, if the neutral and ground were bonded, you shouldn't have read a voltage differential between them.
Awesome video, love the board. Licensed in VA. since '06. Keep up the good work. I've try to explain things to people for years, not easy. A portable version of that board will really come in handy
Another great vid man! In the "why we don't add up breakers" video you said you were gonna go more in depth on the standard and optional load calculations. In that still In the plans for an upcoming video?
Personally you are a good teacher. Ya talk where us part time electricians understand. I live in Florida and it does seem our codes may vary some from northern codes. And materials are a wee bit different. But I truly appreciate your help.
Dustin, can you cover 3-phase wiring in a home shop. There is a lot of smaller older industrial equipment available (woodworking equipment, etc) that DIYers can use if they have 3-phase. I’ve done a lot of single phase wiring but have never dealt with 3-phase.
Good Video Dustin. Another great video idea which you may have done already would be on derating factors and how to use the charts to decide which size/type conductors to use.
Great explanation well done even! Would love to see your ways of upgrading and layout of 200 amp panel from 100 amp, on residential where ac, microwave and other upgrades were not considered but added anyway, turns old panel into a nightmare when troubleshooting or adding etc. Thanks ahead of time.
must be a common residential electricians licensed mistake and homeowners playing into that as well as 150A's-down is no longer relevant as the average person use's more electronics than in say the 1980's and back
@@richardprice5978 exactly! Alot of 70s homes still have the 100 amp, and the owners haven't made the decision to upgrade instead try to pack it all into the smaller panel, and think they are OK, my inlaws for example had issue with tripping breakers when appliances ran and hvac ran at same time, when I dug in found out it was all Jerry rigged to make it functional but not safe or up to code, either had to go through it, to fix it. Figured it might be good content, his presentation is very good and explanations are helpful for those that may not have the know how to begin with.
@@tlheingrunst same i liked his challenger panel explaining for the most part and was vary helpful in telling the miss ( and for translating from are residential licensed man as im on the industrial/maintenance side of it ) why we couldn't just add the generator disconnect or solar system and ended up with a 400A as for the head ache might as well plus we/prior owners had added so much on the 100A/sub-90 socket that it browns out and did start one smaller fireball that we are lucky 🍀it didn't do to much damage and was just a wake up call to fix it the right way and it leaves a little room to grow into it but not much, are utility said over head max they let us go was 150A but had all of the head aches ect so thats not how we redid it
@@tlheingrunst i like learning about historical things but sometimes if really does belong in the past as a box from 1920 would be fascinating to me and others but its missing the last 100 years of knowledge and change ect.
@@richardprice5978 agreed, the old ways are truly interesting, nice to visit, no need really any longer to know the ins and outs. For the most part it's pretty self explanatory.
Your other comment, yes alot of people have gotten away with being lucky playing with their panels and not knowing what they are getting in to. Or doing their due diligence to either get an experienced hand to help, or taking the time to ask questions and learn. In the past I've found homeowners thunk they can tackle so much more than they are capable of because of a diy show, or some self help book or the wing it. Let alone the surprises just walking on site and seeing the rats nest and trying to make heads or tails out of it with no labels either, pencil doesn't last who uses pencil to label? Lol
Thank You very much for what you do here.
Out here in the wilds of Hutto, we have an interesting (to me) set up. This area was apparently wired once before by a different provider as there is wire on the poles with transformers every so often, except all the doors are open. On different poles we have the presently used service feeding underground cables. For my street, we start at the cross street (Front street) with a single phase connection that feeds underground via what I think is an Auto-re-closer. It looks like a normal door except it has a large base that appears as though it could be used to re-connect an areas service remotely. From there they feed pad mounted transformers (I think there are six on my block) and each of these in turn feed up to 4 pedestals located between duplex units. Other streets in this area were apparently razed and rebuilt as single family homes. Each such pedestal feeds 2 duplexes or two homes. We recently had our front yards dug up so that AT&T could add fiber to the area. The city took great effort to keep the water and sewer separated on different sides on the dwellings. Behind my duplex there is a commercial area on Front street. On one pole there is a large, what I am guessing is a switch that can connect the southern part of Front Street to a different circuit. It has what looks like a large slide switch, but then has a cable that runs up to an antenna at the top of the pole. My guess is that this is a remote switch. I have talked to people at the businesses and none mentioned ever seeing or hearing it switch, so I could be wrong. The item at the top of the pole is too thick to be a lightning ground. It definitely looks like an antenna.
This area and most of Pflugerville is serviced by Oncor, which got a lot of bad press when I lived in Pflugerville 20+ years ago for long outage times after a storm. If a breaker could reset it, you were only out 20 minutes. Otherwise we had to wait for a crew to be paged out, get to the office and pick up a truck and then go find the fault. This typically was a 2 or 3 hour outage, and these happened often back then. I have only been out here for a few months with only one outage over 20 minutes, but it was still less than an hour. Sorry for the short novel - that's just the way my brain works.
Going for my journeyman's test on Friday an I definitely know most of this but it was a nice refresh, if you ask me I don't mind the longer videos one bit. It makes me feel like I'm actually learning instead of just skimming thru. Not saying you don't do a great job! Keep up the good work!
I appriciate the videos, im an electrician in training and this stuff just gives me a head star on stuff i gotta learn
Dustin, the new smart board setup is a really great idea! It really helps us visualize the concepts you're describing. I'm still hoping for a video about wiring HVAC systems, especially in commercial environments. I ran across one recently that seemed to be 3 phase for the heat strips and single phase for the blower motor. I know NEC allows for smaller wire to be run with larger breakers, but why? Inrush current? And if the heat strips are 3 phase then would I still base my wiring on the name plate on the blower motor?
I would love a video on "separately derived systems" and delta (isolating) transformer secondaries in reference to grounding and ground faults!!! Thanks so much!
same
Thank you for making this video. It taught me alot. Also I love the service call videos. Please make more. I also do electrical service and it nice to see other opinions on things i see alot.
Amazing kid! Don't sweat the time it takes to explain electricity. Plumbers have pipe. We have raceway. Never ever miss a chance to distinguish us from plumbers. Ha. Watch all your stuff. MORE service calls!!
+1 on the service calls!
don't know if you've made one yet(can't find it), but a breakdown of different panels/manufacturers would be nice. I'm looking to swap out a 60year old panel with something modern and don't know where to start. Maybe also some pro-tips/dos/donts for home-gamers swapping circuits over(or like me, running brand new wire altogether)
Square d qo panel is nice, it’s got some upgraded features over a square d homeline
love your videos! Just curious, what kind of tv and software you are using? I might try to explain to my kids like that, and that will be a lot fun I guess………………
Appreciate the informative videos brother. Keep up the great work!
Dustin I just want to thank you for your channel. Around this time last year my career in mental health abruptly ended very traumatically. I've been floating around until a few weeks ago, doing what I have to do to get by.
As someone who is entering a completely new world, with a hunger to be hyper knowledgeable and successful, but lacking a more labor intensive experience in the work day, knowledge of the language, tools, etc, heck I'm not even very strong either what is the priority for me as an apprentice? 1000 push ups a day? Eating pages of the NEC for breakfast? Continuing to immerse myself in your (and other) channels (again, I don't understand a lot of the technical lingo)?
Eat more Cheerios, 😅 they are full of FIBER OPTICS
Thank you for sharing your knowledge.
Great explained.
Thanks
I looked threw the comments, living here in Florida one thing that I've come across is generators when a hurricane hits people use generators and don't understand that if they don't turn off the main breaker to cut the house off from the service that a transformer works both ways and you can electrocute a worker trying to fix the system. This isn't isolated to Florida, snow can cut off services too... just a thought, thanks for your channel love it, Journeyman Electrician for 10 years now
It is frightening that there really are people who are ignorant enough to actually energize their homes with a generator without taking two seconds to open the main switch. What are they thinking? But hey, people used to put pennies in fuse boxes too...
Wow , this was a terrific video it addressed about a half a dozen hangups I had for years. Thanks a lot. 😃
Excellent video although I was actually expecting a series of videos broken down. You nailed my question though. And this IMO kinda helps lead into some of your other videos. Thanks
Excellent video.
Thanks
Thank you for the excellent video. I will look for more detailed explanation about residential breaker wiring.
Grounding and bonding is always a good video. Many are not educated in the differences between the two and think we "Ground" stuff because electricity looks to a path for ground and saves your life which is not true.
So true, it's looking for a path back to it's source, the transformer, not to ground. Ground can be a path back to the transformer, but it's not the preferred path if the neutral is still intact.
In Finland in urban and suburban environments everything has been underground for 50 years. The transformers typically are hundreds of meters away. There is a distribution box near the house but that is not a transformer.
Thanks for the knowledge brother!!
This is an awesome video. Anyone else would have charged us a bucket load of money for some online course to get this information.
Thanks for the video. Cool to know.
Definitely have the best videos and awesome easy to understand. Appreciate all the work bro.
Great video. This is the kind of video that my wife and kids catch me watching and then just leave me alone and let me be. They can’t complain that i am wasting time like other people watching panda bears on slides.
How about a video on a load calculation for a residence? Love your videos.
What ive been looking for. Amazing content
You're my go to dude. This one was amazing.
You’re awesome dude. Thank you.
Excellent video thanks
You did great! Most of it we don't need to know in the field, but, for me I kinda NEED TO KNOW so thanks man for taking the time explain some the topics concerning the service entrance. Like you I assume, I'm a systems guy,I need to know the whole thing, not just "black to black, white to white, green is ground... blah blah blah" I learned a thing or two or three :)⚡️
In the old days, the grounding wire was connected to the cold-water copper pipe closest to the panel. The last time an electrician came to my home to replace the panel from a 125 amp to a 200 amp, he ran a grounding wire across the house to reach the cold-water entrance on the city side of the main valve. Could you explain why?
In the future, that section of pipe where the ground was attached could get isolated by insertion of a non-conductive section of PEX tubing (or similar) or even bypassed/removed in a remodel so to safeguard against this the best place to connect the cold water ground is where it comes into the house before the meter ensuring that it will always remain connected.
The house I live in was built in 1990. I have a ground wire attached to a cold water pipe, and another wire connected to a grounding rod outside. As it turns out, there is no connection from the copper pipe to the actual ground. Not sure why that is unless a section was replaced at some point, but I've lived there for 22 years, and I never replaced any plumbing.
@@cward1954 The grounding by copper pipe and the grounding by ground rod are independent groundings, they don't get connected directly to each other if that's what you're asking. If Dustin hasn't done it already this would be a great topic for a video too, Service Grounding.
That was a cool video could talk about grounding for barns and why they need a extra grounding
Love you back, friend. Looking forward to the year of answering comment questions!!!👍
Great job Dustin... and thanks for using a colored background so we can see the neutral wires you draw. :)
Nice in-service! Thank you
Hey dustin, love your videos and brand first of all. Second, could you do a part 2 on panels and wiring a main panel with smoke alarms, lights, etc.
Ninicely done! Very educational especially for those of us not in the trade
Good discussion. Thanks
Awesome video Dustin! Could you go more in depth on when youre allowed to use the different temperature ratings for conductors? When can I rate my conductors at 75 degrees, 90 degrees, etc.
Idk how much experience or education you have on industrial controls circuits but I’d love to see a video or a series of videos on industrial control circuits. I started my career as an apprentice worked my way up to journeyman and I soon after that got into electrical maintenance at several manufacturing plants. UA-cam doesn’t have nearly as many videos on industrial controls as I’d like. At least not ones that are made by video makers that speak English anyway. Great vid as always keep up the good work.
Fantastic explanation.
Thanks for the knowledge pls i wanna know all the things to need to know as an industrial electrician.
thank u.
Thank you sir to much I learn this video godbless you
Exelent videos tnks
Very thorough intro!
Awesome video. Can you do one on how 480v 3 phase lighting works? Thanks.
Keep up good work. Thanks
Overall a good try to get it all in! Possible video topics. Overcurrent protection, what, why, and how, breakers and fuses. NM cable. Uses permitted, not permitted, different types. Separately derived systems. What, why, and grounding. Generators, transformers, etc.
Respectfully, Kevin
Thanks for the video =)
You are doing everyone in the electrical Trade a big service! What’s funny is I became and electrician because of the video you made years and years ago of “why you should be an electrician”
Good video man. Shoulda had a lineman on with you to explain more in depth the utility side
Yeah, the linemen would have pulled the fuse to disconnect (assuming only the dwelling was on the transformer) point out the neutral on the utility pole, then point at the ground rods every x amount of poles because some dyi played with a generator thats back-feeding the phase(s) causing everyone to slap jumpers on to neutral while they fix shit on storm duty.
Something like that
I live out in a rural area and also been an electrician a minute. One thing I’ve noticed is power companies often drop to one line in really rural areas. My question is go do you get a neutral at the residential service with just one line?
I love to see you do house generators Way they work the wiring transfer switches
Have you done any videos on box fill and how to calculate what size box you need for the number of conductors and devices? That would be helpful.
Great video! Thanks for sharing such informative content. One thing I noticed was when discussing the different conductors temperature ratings, there was no mention of the OCPD temperature rating that must correspond with the conductor terminated to the OCPD. Do I understand that correctly?
Great video I think it be very interesting to see the methods and requirements to installing/building commercial fire alarm systems
Thanks!
Great Job 👍🏽⚡️
Dustin can you put a video doing standard and optional method
Where is the Wye circuit, which is used for providing a neutral, placed when wiring up an apartment building with 3-phase? Is it at the transformer?
Yes. On the secondary.
Good informative video. It's been nice since you got your smart board.

Great Video.
Really good video
Awesome video
Excellent. Can you please cover bonded neutral vs floating neutral related to portable backup generators that back feed a panel interlock switch. Thanks.
I enjoy your videos. My home is on 6 acres and I am having my service put underground. The power Company came out and looked at my setup and suggested I change from a single-phase setup to a 3 phase setup. from 200amp to 320 amp system. They said because I have my house and an RV setup and I plan to build a shop and maybe one other building. I have watched your videos about single phase and 3 phase and the videos on above ground and underground. Is there anything I should be aware of when changing a house over from single to 3 phases that could be a problem?
I work for maintenance in a shopping mall with about 6 electrical rooms for powering the main area(none of the stores) and they lost a lot of the lists you place inside the panels and others are just listed wrong/poorly for example if it said "soffit lights" but the breakers actually go to the fascia lights. Any chance you could show us the easiest way to trace wires and any tips or tricks you have with larger buildings like this?
Dude I’d love to see more about where you’d use which raceway. I’ve got a job coming up I’m not sure what’s best to use or even what’d be easiest
Wires and raceways will be a great video!
Can you do a video on switch gears and transformers ? I just started learning distribution would be cool to learn more before starting
Can you do a video on grounding rods, lightning arrestors, lightning rods and other surge/lightning mitigations?
