That was a good explanation

How do you determined the trade size is 53 after going to T6j TW?

Great video, which program are you using to build the schematic?

Hello Schuler ruler. Do you teach CEC 2024 via zoom? i could pay for tutorials. Hoping you to response back. Thank you in advance!

Schuler! You were one of my instructors at sait as an apprentice. I've since moved to BC and bought an electrical contracting company. I'm tutoring at TRU in Kamloops for the electrical trades program as well now. I saw your RUclips page on the whiteboard of the class I'm in. Good job! I remember using it in school looks like it's still happening. Congrats!

I absolutly love your videos! They are definitly my go to suggestion for students who want video tutorials. Quick question, for a motor voltage drop calculation, do you use your FLA or the FLA x 1.25 to obtain your distance from Table D3 and in determining the distance correction factor (load ampacity/conductors ampacity at the rated insulation temperature). The CEC handbook uses FLA to determine the distance in m from Table D3 and uses the FLA x 1.25 to calculate the percent of allowable ampacity. Just curious if there is a mistake or if there is an explanation for this? I couldnt find an explanation or example anywhere! (None at least based on the CEC.)

Thank you

thanks for speaking in real english 😭😭😭

Great video man

Thank you for this video

Thanks man!

Thanks❤❤

Instead of focusing on the explanation he provided, I have been shockingly surprised by how he was writing. Was he behind a glass board with a camera in front of him? If so, how on the earth was he able to write from the back side? Did he train himself to write in mirrored fonts??

As well.....if the short is grounded by a ground wire that goes to the ground bar in panel and goes into the ground via ground rod and system neutral grounding. If the metal boxing, panels, metal raceways, etc are bonded to ground, yes they are energized too by the short but are safely carried away to grounding mechanisms. All this to protect YOU from becoming a big resistor going to ground.

👍

One of the best instructors to come out of SAIT, and I didn't even have you.

Fantastic explanation

Dude, what about derating factors? Table 5c?

3kW for a tankless water heater? Isn’t more?

Thank you!

Awesome! I finally found the explanation I was looking for. Thank You for posting your knowledge.

Thanks!

super helpful thank u

excellent

You earned a subscribe

Thank you very much for what you do! This helped me a lot

You basically showed the same path for both. What is the grounding wire from the ground bar to the grounding rod for if both faults go up to the service neutral and when do we remove the bonding screw from the grounding bar in the panel? Nothing was explained yet again

Fellow Canadian Sparky! if your still active on this channel, i have questions/comments that you might be able to answer. One, I heard that the curriculum is going to be updated finally, which will change when certain topics are learned, eliminating certain topics, and the length of the terms. Two, I read somewhere (that seemed legit) that some skilled trades will grant accreditation towards secondary schooling. Also, possibly a new way for the government, employers, and apprentices to navigate the whole apprenticeship process (I personally think that an app could easily replace AIT's middle man role and just have them around for enforcing/policing, as bad as it sounds). Any answers/comments are appreciated from anyone Btw, you've helped so many of us with your vids bro. Love you <3

I'm trying to calculate an ISO or German motor with a cosine of 0,95 ~ My understanding is that "european" motors are basically at factors of 1 on down to 0.85 or so which isn't very efficient. So if the motorplate says AMPS at 3.4 ~ with a cosin of 0.95 I would set my overload "at basically" 3.4 Amps IS THIS CORRECT?

It's hot == Swithed on/Under Load Wire nuts / connectors = cups for wires common guys

Thanks for the presentation, but I'm unsure if this is code compliance because the bonding conductor was not addressed here? so how the fault current will travel through the natural conductor ? or grounding conductor for the branch circuit, you provided only grounding but no bonding.

What if one of the transformers is a different size? Such as one being a 15kva and the other a 10kva?

At First Energy we called the middle pot (that's 120/240) the Lighting Pot. Smallest config wud be two 25 KVA wing pots and a 50 KVA lighting pot. Usually the three phase load is smaller than the 120/240 load in commercial customer. On occasion, all three would be 25 KVA minimum.

hey quick question!! when there is a device present ( switch, outlet) do we use the largest conductor for caluclating the 2 conductors the code requires use to account for the device? or can we use the smallest wire for the volume calculation?

I really learnt so many basic concepts from your videos, Thank you for making this so easy to learn i got one question for you Suppose if i have to design one transformer and i have to select WIRE SIZE on primary side so what should i consider for Amps by Phase current or Line current( if primary is Delta)

What does "I z" mean ?

goddamn your videos are so helpful, I was lost learning this in school but you lay out each step really well, Thanks!

Please note that this video is inaccurate for American NEC code. Especially when discussing the OCPD sizing which is calculated off rhe load, never exceeding 80% of the OCPD even when non continuous loads are used.

Nice explanation sir thank you very much

Nice explanation

so what if the wire size is # 12 ( or smaller then #4). apx 40 wires coming into a 24X24X6 jb from the back with 2" conduit. what calculation would I use. BTW love the videos.

CEC2021 26-250 Overcurrent protection for power and distribution transformer circuits rated over 750 V

Thank you Chris

Another question, what’s with the red line connection that you make between the primary and secondary? I thought transformers are separately derived systems with no conductive path connecting primary to the secondary, but rather operate via mutual inductance.

What determines the letters H1 H2 and X1 X2? In both your depictions all we can see is that you draw H1 and X1 adjacent to eachother and H1 and X1 crossed from one another, but what about the windings in an actual transformer determines which letter goes where?

Hi sir, I watched your video before my red seal exam, and it was very helpful. Thanks for sharing your knowledge!
