Hi Zack!, I really appreciate for your training videos. I read a lot of Canadian standard codes, but your videos are very very specific and now I find out how to do the sizing calculation for the O/C, cables, etc.. I wish you all the best luck :)
Hi Zack! In the field you often hear that we are "choking this transformer". I was hoping you may have some insight as per the code book as to how this is done? Loved your lectures, these videos are great as well. Thank you!
Hi Zack 1.25 is minimum demand for cable. actual size of conductor depend on protection method. For example if there is high voltage (over 750V) transformer the minimum size of fuse will be 150% then if we select a cable according to 125% primary current there will be a big gap between fuse rating and cable ampacity and as section 14 over current protection can not be larger than cable ampacity, in this case we can not consider 125% demand factor for conductor and need to jump to 150% for sizing conductor. If protection is by breaker (300%) cable size should be sized accordingly. please correct me if i am wrong
Hi Zack! , Where does the 1,25 come from? Can we apply this rule to all circuits when it comes to calculating conductor size? e.g while calculating conductor size for a diesel generator or any loads on the distribution panel
Great video. CEC says 25%! Not 125% of highest primary current plus the sum of other primary current for transformers in parallel unless my book has a typo really hope that is not the case😬
I was sooooo thrown off! I couldn't believe what I saw in this video, and was getting ready to expose this guy for fraud and misinformation! THEN I realized it is not the USA electrical code! 😂 I like the Canadian code better, it's more simple. 👍
