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

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

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 :)

Abouzarfallah, thanks for the comment. Although I agree with some of the logic you have described, it really depends on where the fault originates. If the fault is prior to the secondary OC, then yes, no fault current would flow through this OC-and it would not trip. I this situation we would be depending on the primary OC to trip due to the increase in primary current. Although it may seem imperative to always design the system with maximum safety, the CEC rules are there to provide a balance to equipment cost-in this case, sizing the system bonding jumper from the first OC protecting the separately derived system (secondary OC). Most likely, the fault current-in the worst case-wiuld case such a sharp increase in current that the primary OC would trip. Great question.

My pleasure, just trying to assist apprentices along the way.

No problem, just trying to make things a bit easier for the average apprentice in training.

Thanks for the comment. Just trying to make stuff available which assists individuals through their apprenticeship training.

@@Red_Seal_Electricin it totally helps hearing It explained a different way . I'm in my 4th period of schooling and your videos are downright excellent !

Actually, the ITA provides the necessary Sharp calculators (mode 3 calculators) for the apprentice final TQ exams. Just like numbering system conversions, if you know how to do it, the process is quick and efficient.

@@Red_Seal_Electricin Yep I am dead wrong

Thanks for the comment. I totally agree with you, this appears to have been an oversight. Thanks for letting me know!

Afternoon, Table 10 was used because of different types/sizes of wire. In the 2024 edition table 10 has been deleted, along with some adjustment of values means we will only be using table 6, 8, 9 going forward.

Glad to hear it, the CEC can be a challenge at the best of times. Check out my playlists for lots of L3 relevant 3phase calcs.

@@Red_Seal_Electricin I will for sure be checking them out :)

I believe there is one of each shown in the video. Thanks for the comment.

Depending on the country you reside in, the standard for where the EOL is mounted can change. In Canada, it is more common to have the EOL in it's own separate box. Thanks for the comment.

Thanks for the note. For sure, this is a valid calculation which often gets difficult to interpret. I'll see about drafting something this month.

Thanks!

Thanks for your comment. There will be many times throughout this presentation that specific details are waxed over. This is intentionall-and required to a point-due to the targeted audience. The channel presentation are targeted for the Canadian electrical apprenticeship program. The depth and scope of which is intentionally shallow on some topics that an average electrician would not often work on. Thanks again for your comment.

Perhaps in the future. I am attempting to keep videos within the topic boundaries of electrical apprenticeship in Canada.

Great idea, however the scope of the channel is focused on electrical apprenticeship topics. Perhaps over time there will be further expansion into other areas. Thanks for the idea.

I completely agree with you Colin on all aspects that you mentioned. The only reason I continue to provide detail on this method is simply due to its inclusion in provincial objectives for the electrical program in Canada & the Red Seal. Its application flys in the face of hazard mitigation and live work procedures. Thanks for your comment!

Excellent idea, and one which has already been developed. Check out my playlists on motors.

Yes, there is one already developed for the older style of mechanical sync starter. Check it out I my playlists.

That's a great idea, I'll see about developing something on this topic.

@@Red_Seal_Electricin thank you sir

There is some TX working principles discussed in the 1phase transformer presentations. Check out my playlists.

@@Red_Seal_Electricin thank you sir

Thanks for the recommendation. If you provide some more clarity, I'll see what I can do.

@@Red_Seal_Electricin your explanation very good sir
