Understanding Blueprints: Electrical Symbols Explained

[@nunoaugusto20]

I have to tell you something. I'm an apprentice, I have 30 years old so I don't have the same habits that the younger generation has. Besides that, I'm Portuguese, and I work with American and Hispanic people, so the language I kind of a barrier. With your videos, I started bending pipes by myself, checking the blueprint, boxes, mc cables, you name it. I knew all the materials in the first two or tree days because of you. I have to thank you, because with your help I'm getting to enjoy my work, and all I have is positive feedback. Thank you!

Studying to be a cost estimator for a electrical, wanted to say thank you for the lesson. Not a lot of quality content on KZbin for the topic so this is much appreciated.

You are the man thank you for my raise…..

[@jasonh8542]

this was great. hope you will do more electrical symbols. I feel this is a overlooked for many Electrician influencers.

[@ybloc1428]

That's awesome! Could you do one on electrical diagrams for devices like generators or tracing wires through enclosures in a plant settings?

[@jay5.77]

Got to write out some plans on my test next week for my electrical class, thank you dude🙏

[@zokotziggy3981]

Hey bro , my teacher gave me because of your notes. Thank you salute from Haiti

[@Hatim.13]

Thanks alot Dustin! You re the reason I am in the electrical trade (1.5 year non union and 10 months IBEW), I would ve been a plumber otherwise!

[@Wizard__J]

Out here in Jersey we call them big eyes! Good video! It’s covered things I haven’t seen yet before, but extensive otherwise, and covered pretty much everything we do lol, ty for this

[@Bennerover]

Been needing this video! Thank you!

[@RCRoads]

Thanks for sharing. Landscape stub is a new one for me. Great advice on running a 3 wire for landscape lighting.

[@dmt5codm811]

pls do more of these videos, I really appreciate them

[@garyarthurs]

I can’t speak to the history concerning how electricians may have used the terms 220 V and 240 V differently over time, but just a friendly tip that there is actually a difference. Check out IEEE Standard 141-1993 (aka The Red Book). See Table 3-1 on page 63 (pdf page 79 of 765). 240 is a “Nominal System Voltage” (aka the supply voltage). 220 is a “Utilization” voltage (aka what the equipment is designed to utilize). The idea is to account for voltage drop between the supply and the equipment. Thus the supply voltage of 240 V is higher than the utilization voltage of 220 V. The voltage drop can of course vary which is one reason the equipment is designed to operate over a range, e.g. 220 V +/- a percentage. Hope that helps.

Pro tip, if you have a fresh out of college engineer that thinks they know everything on the job site, make up random symbols and draw them in all the wrong spots. You'll get peace and quiet all day.

[@brainmeat1]

Thanks for the videos Dustin. I’ve really appreciated these recent blueprint tutorials you’ve been making. Would love it if you made a video in the future explaining the process of running an entire commercial electrical project from start to finish. Perhaps some tips on staying organized and keeping a crew busy.

[@ghostofgalileo84]

Great explanation! Please make more of these.

[@darkflux]

the "NITCH" vs "NEESH" thing is an old argument. it is actually "NEESH", as niche is a French word, like quiche, but many Americans back in the day we did not have good schools, and so many people incorrectly pronounced the word as they read it in books as "NITCH" (and honestly, some people pronounced it that way just to be silly, but then others just thought that was how it was pronounced, and emulated that!). so the "American pronunciation" was actually an "American MISpronunciation" which just stuck and spread. likewise with cache, another French root word. some people pronounce it "CAH-SHAY", but it actually doesn't have the little accent over the e, so it is just "CASH". what's even worse is that English pulls from several different Latin-based languages: French, German, Spanish, Italian, and even Russian and others sometimes. so we get words like lich, which IS pronounced "LITCH", that throws all the other words into question, lol. i always look at the etymology or origin of the word. that often gives you an idea of how to pronounce it. it reminds me of when i was a kid, my younger sister always tried to prove herself smarter than me, and this one time, she used a word "AW-REE". and i said to her "AW-REE?" and she said "Yeah, you know, when things go wrong, people say they have gone "AW-REE". and i said "You mean 'UH-RYE'?" and she said "NO! 'AW-REE'! A-W-R-Y!" so it's a problem wether you are reading a book or hearing somebody say it to you directly. you never know who's right!

[@johnburgess2084]

I've wondered who (Electrician or Architect) is responsible for making sure lighting and electrical meets BUILDING codes? I know that you, as an electrician can wire an area that meets all electrical code, but the plans might omit required Exit signs, or satisfactory power capability for the likely intended purpose? And then the customer has to pay you again to come back out and fix THEIR design errors.

[@curtw8827]

Whoever signed/sealed the drawings is responsible for the design to meet Code. The electrician is responsible to install his/her work as shown on the drawings per the Code minimum unless the drawings indicate work that exceeds the Code minimum.

[@jongorman346]

Huh..Always great content..our symbols up in the north run the other way...like 2 vertical lines in circle for duplex. Always great content and pretty cool to see how things are in other parts of the country

[@benlawmusicofficial]

Killer video! This was super helpful! I gotta say thank you as I’ve learned so much from watching every one of your videos I can! Regarding this topic though, what about hardwired devices such as disposals, electric fireplaces, hot water heaters etc? How would you indicate those on a plan?

[@refraf8030]

I don’t want to be an electrician I am however a dilettante lol . This video was incredibly clear for someone like myself who has little to no experience with blueprint reading to understand.

[@robertmartin5167]

love your video . can you do a video on smoke detector, locations and how to run wires with W s

[@mattdelaney584]

A big thing happening in the industry with commercial, industrial and the addition of BESS systems is the need and requirements for As-Built drawings. Should get this discussion into your blue print videos. It's a big skill to have to keep track of and document dwg mark ups.

[@josegaitan7105]

Dude you're awesome man I learned a lot from you man

Cómo puedo conseguir libros o videos de presupuestos can you help me with that? Please

[@LumpyYT]

This is probably a silly question but why does the outlet say 150v with the multimeter?It also says the neutral to ground has a current can this be wires crossed or do you have any advice?

[@atmtim3783]

Preciate the info bro

[@brianwarren6886]

2X4 night lights often have battery backup in them too.

[@THE-T7]

What happens if the live became shared when the live wire and the neutral wire are reversed on the main breaker without grounding ???and why every thing turn off in the kitchen when i unplug the refrigerator and back on when i plug it back this is a real case !! our standard is 220v- (50 Hz)

More blueprint videos.

[@CatholicElectrician]

One of our contractors used these lights that we call “fake recess.” They mount to a standard ceiling box but they’re made to look like 6in recess trims because he’s too cheap for real cans

[@throttlebottle5906]

I kind of like those, since there's future flexibility for installing other forms of "non-recessed lighting.

[@curtw8827]

Or you could just look at the legend table.

Why do you have that receptacle Fed out of the lighting panel 😂 just busting ⚽️ s
