Thanks for the compliments Sanchez. In regards to the 442A, I will be working on some additional videos shortly the assist with PLCs, magnetic starters, and the 2024 CEC.

Cheers, that's the intent. Electrical is tricky, invisible & dangerous. Hence the requirement to know EXACTLY what will happen when we connect wire A to wire B. I'm glad the content is helping you along the path with your career. Best of luck on your upcoming 442A Ontario exam!

@Red_Seal_Electricin thanks a lot

Glad this has helped you. The grammer in that section 4 rule is ridiculous!

Glad I could help you Jean Claude, TX calcs can be tricky in the CEC...

Ahhhhhh yes. You will fnd a video on this in the CEC playlist under Section 26, Motors & Capacitors. These can be tricky applications!

Excellent find! Yes this app B info is very pertinent to the discussion. Thanks for sharing it here!

Pleasure! I totally understand the challenges associated with training in the electrical field. Hopefully these vids will make the burden of learning a little easier-helping make the next generation of effective field electricians!

@Red_Seal_Electricin I spent countless hours searching for answers .Your videos make gaing practical on point knowledge so much easier .I am really grateful that u r sharing this with us .

Absolutley fantastic. Really glad to hear uncre838. Each level of training poses it's own unique challenges, good luck on your L4 final & Red Seal exams. Your career is about to begin!

My pleasure. The CEC is a dense read that really requires additional visuals to make sense of. Glad its assisting!

Interesting question! At time marker 13:58 you can see me pointing at the divide 0.8, which covers the 80% efficiency of the three motors. So to answer your question, I did! Is there somewhere else you were thinking?

Hi there, this is a manual I wrote for CEC calculations years ago for the electrical department I was a part of. At this point, I am determining next steps for copyright & distribution.

@@Red_Seal_Electricin thanks for the reply! I hope you're able to publish it someday. It looks far better than the manuals currently available from CSA.

Hi ziplock, glad to hear they are helpful! Yes, this was something I was planning on uploading over Christmas. There are a number of additional videos on HV, PLC & CEC 2024 changes that I have wanted to get too. Just waiting for the time to get 'em done. Any other ideas are welcome!

@@Red_Seal_ElectricinSi r, you are very much valuable for providing us knowledge videos in a very easy way which can make any one in electrical field to understand CEC. CEC is very vast field of information and understanding by reading book is just a huge task. Your contribution can trigger basic understanding of CEC chapters to hit this overall huge tasks completion. May God bless you and keep motivated for doing good stuff. Also waiting your Christmas gifts in terms of new videos release to all of those struggling to go through CEC stuff. Sincere Thank you for doing this.

Thanks for the comment ziprock, I totally agree. It took me many years to finally realize the actual differences between cable types-and their actual names. Once I had that clear it really helped me in identifing the rationale for different requirements in the codebook. Simply put, now when I read the CEC, I can picture the cable being referenced.

LOL, I think the details of their shouts may not be appropriate on RUclips comments

Hi there littletyke, your confusing the difference between calculating individual OC protection for a branch cct and calculating the max OC of each branch for determining the main. When doing the later, one must use the multiplier that corresponds to the OC type that aligns with the main. It can be confusing. I encourage you to walk through the video again, along with the CEC rules for reference.

@@Red_Seal_Electricin Thanks, appreciate it, I see where I went wrong!

Good question. The rule indicates we cannot select an OC larger than what is calculated. Since 150A is a standard size OC in Table 13, we are permitted to use it. Remember, we can select an OC equivalent-to or smaller-than the maximum calculated. Its similar to speed limits on the road. 100km/h or slower is acceptable to drive at on the highway, but no faster. Hope that helps...

@@Red_Seal_Electricin Thanks, but for exams purposes, 125A is the correct answer?

@@ricardod4321 If the number falls on exactly on 150A then 150A breaker is fine. If it fell on 149A then you would size down

@@littletyke76 Got it, thanks!

Hi Zwang, yes that is correct. A depreciating suite calculation would be done for the main service, then again for the feeders supplying each floor. Good question.

Appreciated.

Lol, thanks for the compliment guangyang. The CEC is an intensely challenging document for a number of reasons-you are not alone in your confusion. Not only is it highly technical, but it also uses English grammatical nuances that have not been used by native speakers for decades. Perhaps one day Canada will align with the US in their codes. The American national electrical code, NFPA70, is far easier to read.

Cheers, thanks for the comment. Education is a challenging task in every sector-the electrical trades included. Perhaps, in time, educators will reach beyond the basics of their texts and creatively connect concepts to the field.

Hope it helped in the studying!

My pleasure, hopefully it was helpful.

Cheers baniceeee. I hope you find things here that will improve your understanding of this exceptional career path.

Thanks MTfor2023. Anything to help apprentices along the way. School can be challenging, I hope my videos can take some of the edge off!

It really does. Again amazing work ​@@Red_Seal_Electricin

Hi dragon818, in reference to box fill, any receptacle is considered to be mijnted one single strap. This would include single receptacles, duplex, and other quirky combos such as a switch with light or switch with receptacle. Let me know if I understood your question correctly.

@ Hi there, the 14-30R usually uses for a dryer, it is larger than a single strap. Does that count 2 straps?

Cheers, glad this is helping you along your training path.

Glad this helps. It can be a challenge to find Canadian content-especially with the calculations. Depending o the province you are training in there can be quite a difficency of learning resources...

LOL, I do enjoy a good mountain goat. Glad this video was of assistance to you!

Great idea. It has changed-for the better! I'll get that put out soon.

@Red_Seal_ElectriciThanks a bunch, see if you can do a comprehensive take on all orientations, for example: known conductor, known length, or known CCT size individually.

In CEC table d3 there's an example we multiply those numbers why did you divide them? Kinda confused now

Hi there, as long as you follow the process laid out section 26 CEC you should be fine. It is always up to the designer to determine if they will size based on load, or size based on TX capacity. The choice is yours...

Good question, the only change to the calculation is the requirement to remove EVC AND climate (heat AC) when determining suite demand. Also, there is no longer an EVC demand table, deleted. Should have been done years ago, terrible table. There currently is a mistaken omission for the total service apartment calculation. The CEC currently does not provide a process to add the suite EVC load back into the total service calc. Check your local province to determine how this will be dealt with.

Habks for the question. This could have been better articulated during the tutorial. There really is no reason why this could not be a single phase transformer. In some respects it may actually make more sense considering the tx ratings shown. In a course/assignment it would need to be clarified to ensure students are aware of the tx configuration.

Great question, typically no. The volume of wire contained in a box by these conductors is so small that it is not considered significant enough to count. This is evident with table 22 & 23 having volume data down to #14awg, no smaller.

Good question. Volume of the two boxes added together, typically twice the volume for a gangable box.. no need to subtract sides.

Thanks for the comment. I am considering the possibility of sharing files in the future, but presently no immediate changes are planned.

Good question. 4-004(13) states a maximum of 600mm that multiple multiconductor cables can be in contact before deration must be applied from T5C.

@@Red_Seal_Electricin thank you Do you have any videos about that?

My pleasure, keep up the studying!

My pleasure. Glad it was helpful.

Thanks! I'll be coming out with a big code update presentation later this month which may interest you.

My pleasure. I'll be coming out with a big code update presentation later this month which may interest you.

Thanks for the comment munchkin eater. This is a good trade, you have chosen well! At this time I am not conducting tutoring sessions, although that is an interesting idea for the future. Level 1 will be allot of DC theory & CEC. If you know what CEC topics will be covered, searching on my channel should render some relevant videos-on most-but not all topics.

Indeed I do. But one can at least rewind and replay if necessary-which cannot be said of a face-to-face classroom environment.

turn the playback speed to .75

Hello, thanks for the comment. Indeed the secondary circuit is challenging when calculating wound rotor motors. If you take a look at my Specialty motor calculations from Section 28, further rule reference and directions are provided.

Thanks for the comment. My pleasure, hopefully the content provided will assist you through your apprenticeship levels of training!

Good to hear. Thanks for the comment

Great to hear, thanks for the comment

Hi good job. That’s need to know everyone.

Not a problem, Soars Book on Grounding & Bonding IAEI This has been the best resource I have found for many years. Clear, concise, color images, excellent rationale and application-even for rare situations and systems. Every journeyman electrician should read this book before the end of their technical training. Thanks for the question.

Tap conductors length is 7.5 m or less -> Rule 14-100 1) c) Item i) or ii), whichever is greater: i) one-third of the overcurrent device that is protecting the feeder conductor Or ii) The rating of the overcurrent device that the tap conductor supplies

@@Dayvon11 Sorry I think I asked my question wrongly. I mean that how should we size a bonding conductor for a tapped circuit? for example what is a bonding conductor size for a 5 meter tapped conductor which come out of a 125A splitter?

This is a great situation you bring up Abouzarfallah. Although the bonding rules do not provide specific directions for this situation, it is likely your local inspector would require the bond to be the greater of 10-616(3)(a) or (b). If larger tap conductors were chosen from 14-100(c), it would be logical to increase the size of the bond to carry the increase capability of the tap during fault conditions. By the way, my name is not Alex :)
