Hey man, i just wanted to come on here an say thanks for what you do. I just wrote and successfully passed my Ip (nova scotia but living and working in alberta) Your tap conductor segment and service calculations prepared me so well for the questions that i had on my ip. Thanks again!
A lot of this information I already know, but this is the PERFECT refresher, hell, even if you've never learned this. Very organized thoughts and explainations! Incredible work!
Quick question, for choosing the #2 AWG wire is because you always round up on your ampacity correct. Even if #3 AWG is closer to your amp load you always round up and use the wire above it.
Hi there, great video. I just have one question, would any of these values or basement area calculations change if it is for a secondary basement suite? Or would it still be calculated at 75%? Thanks!
if i am right, you have omitted rule 8-104 6) a) b). while calculating the ampacity. it should be 26.3k/0.8= 32.8k. 32.8k/0.24kv=136.67A. T2->75 deg->1/0 wire. Kindly correct if i am wrong.
@@schulerruler Thank you for your quick response and clarification. I really appreciate it. I have encountered a problem where 8-104 6) was applied. However, I am still not clear about where to apply rule 8-104 6).
Would you not need to increase the wire ampacity to the ocpd rating due to 14-100 d) ii)? Otherwise this 125A breaker would not provide overcurrent protection (only ground fault/short circuit) for the wire?
Schulerruler, Excellent Video. I don't have access to a Canadian Electrical Code Book. Can you help? I'm planning a 40' x 64' Workshop perhaps for light commercial work at some point. I thought I could get by with a 60 Amp Service but looking towards the future I think 100 Amp is more appropriate. Does Cdn Code differentiate between Residential / Shop / Lt Commercial ? Someone suggested using a Rule of Thumb - 3 Watts per square ft for Lighting and Receptacles. 40' x 64' = 2560 Sq Ft x 3W = 7680W / 120 or 240 = 64A or 32A I've done my load calculations and fall well with 100 Amps. Catering for a Stage II EV Charger from time to time is my biggest load by far going forward. Am' i on the right track? Thank you.
thanks for teh videos man it really helps! theyre so much better than my teacher. Question, where do I find the number of spaces needed for the panel board at the end of the question, in the 2021 CEC? the rules changed and its not there anymore
The size of the panel is now determined based on the branch circuit requirements, with an additional 4 120v spaces left over. As opposed to a minimum number of spaces plus 2 120v spaces. You would need to add up branch circuits for receptacles, lighting, etc and include any other loads with they're own overcurrent.
Hi my friend, thank you so much and your video is so helpful for me, just one question, why don't you choice the smaller overcurrent size? Just like for motor. Thank you again.
The method used for academic purposes selects the largest overcurrent. This harmonizes answers. In the field you could go with the smaller size, but if the load is known, and is in accordance with section 8, we are permitted to use the next size available, up to 800 amps.
@@schulerruler Hi man, sorry to bother you. Just one thing confused me that "how many supply services of the same voltage are required to be run to a six unit row housing condominium complex, where each consumer has its own service?" I got the answer is 2, but it says four in Rule 6-104. Could you help me? Thank you, have a great day.
Bahamas has adopted Canadian electrical code. Check the representatives for the code by jurisdiction at the front of the good book and you'll find Bahamas representatives listed.
What do you do if you have an electric cooktop and an electric stove that are not combined as one unit? 6000 for each? Or can the oven have a factor of 25% applied to it, as covered in section vii)A)
Check out 8-300 2) as it specifically deals with that situation. The two would be added together and treated as one unit for branch circuit calculation purposes. If you have a separate range (likes a secondary) it can be added as per 8-200 1)a)vii) as noted in the same rule in appendix B.
Good day. Thank you so much for the videos. I am writing my IP end of October and I still have so much to learn. Is there any way to contact you and ask some questions or just ask here?
for the dimensions of the house, doesn't 8-110 state the living area should be determined from the inside dimensions of the house (like, subtract the walls)? i will pretend the house walls are thin :D
I quess there is wrong in calculation of area. 1st floor and 2nd floor are good it was converted into mm² beacause 110m convert to mm² is 220mm², but the basement i feel something wrong on area. 110m×.75=82.5m convert to mm² is 165mm²
what are you talking about??? The unit is m^2, he added up the value from first and second floor (both 110m^2 because you take 100% of the liveable space above grade ) to get the 220m^2. The 82.5m^2 is because the code says when you're taking the value from the basement you use 75% of it so 110m^2 x 0.75 = 82.5m^2

That's awesome to hear! Congratulations and good luck on your future efforts!
any advice on the test?

One of the best instructors to come out of SAIT, and I didn't even have you.
Great video - showed this to my woman who's having a hard time with this. Its helped her lots! Right on man
Happy it helped! Their for watching!
Fantastic videos. Started casually watching these before my 4th year and its really made a world of difference.
I'm happy to hear that! Good luck in 4th year! Which province?
Outstanding video. Good job brother. These videos are very helpful. Taking my exam late aug. Hope i will pass. Thank you. God Bless.
Thank you my friend. Good luck on your exam!

thanks for posting this i have a code exam tomorrow big help
This is a very helpful explanation of service. Would a “heated” crawl space (gas furnace or heat pump) be considered when calculating living space?
With the wording of the 2024, we now consider any basement or crawlspace with more than 1.8m from the lowest point of the ceiling to the floor at 75%.
Can you say something about calculations for tiny homes? Either on a foundation, with and without basement, as well as a tiny home on wheels (THOW)?

8-200 3) states that the load calculated from 8-200 1) shall be considered non continuous, so applying the 80% is not required.

It is so refreshing to find a clear communicator who can help with the CEC, you must teach at an Alberta college. Where are you located?

(Ps. Much respect from the bahamas)
so you have the same code in the bahamas as they do in canada? probably not

Hi sir
Please make one for a complex building calculations

wow another thing I just took for granted 100 amp or 200 amp depends on the loads in the house and size. Ok again now I know.
