On the question at 23:14 of the video, it asks about using THHN, which only exists in the 90 degree C column of the ampacity table, so when you choose the final size based on 186.75 amps, shouldn't the answer come from the 90 degree column, which would be 2/0?
on the motor short circuit / ground fault protection, the question about 7.5 HP 230v the calculations you mentioned was 40 x 8.00 = 350 I calculated 320? next size up would be 325 answer C. ? I'm not sure if I'm missing a step?
Which test questions fall under Branch circuit and Feeders, is just sizing conductor sizes and overcurrent questions , I just took my masters past Monday failed my calculations portion by one question. You’re videos are the best on TH-cam, i appreciate what you do.
When sizing over current protection for motors, I thought you are supposed to use the tables in 430.247, 248,249......and not the motor nameplate current
Thank you for your videos. But I have a question on the second question box fill calculations. Please feel free to correct me if I’m wrong but according to 314.16 (b) (4) each yolk would have a double volume allowance in accordance with table 314.16 (b). So going to the table , for example, the size of my conductor 12 in.³ is 2.25 so we were times that by two so for each yoke with 12 wire, running to it, we would count that as 5 in.³. So I came up with 48 answer A. Thank you
24:10 we just gonna let it slide that b was really 2/0 :P. i was pressed when i found my answer and it wasn't up there only for him to come up with the same answer and just the answer options lol

Let's go!!!
At 13:38 when sizing Short circuit/ Ground fault protection question
you put 40 x 8.00 = 350, when actually 40 x 8.00 = 320
?
@7:30 EGC total cubic for a box. How would you do the calculation under the 2014 NEC?
Thank you!
Great question, you would use the exact same method!!
On the question at 23:14 of the video, it asks about using THHN, which only exists in the 90 degree C column of the ampacity table, so when you choose the final size based on 186.75 amps, shouldn't the answer come from the 90 degree column, which would be 2/0?
Great question, no you would select from the terminal size regardless.
on the motor short circuit / ground fault protection, the question about 7.5 HP 230v the calculations you mentioned was 40 x 8.00 = 350 I calculated 320? next size up would be 325 answer C. ? I'm not sure if I'm missing a step?
Great question. You head to 240.6(a) and select bthe next standard size it jumps from 300 to 350 there is no 325 standard.
Yes I was wondering the same, the math is just incorrect but breaker size correct
I see looks like I jumped ahead!!
How do you know when to size up or down for breakers when sizing different breaker types for motors?
Up on short circuit ground fault protection
Down on overloads
@@ElectricalCodeCoach thank you very much. And down on a feeder feeding multiple motors?
@@ElectricalCodeCoach hey coach thanks, does this include all the breakers in the chart to go up?
When calculating the general lighting load, how come we still add the 4500 for small appliances and and laundry?
Is it possible to edit in "Standard Method" in red, as in your other videos, for the questions at 24:56 and 28:26?

Motor- Short Circuit Ground Fault Protection-use the table FLC.
Motor- Overload-use the Nameplate FLA.

Thank you
2.25 x 2 = 4.5
24:10 we just gonna let it slide that b was really 2/0 :P. i was pressed when i found my answer and it wasn't up there only for him to come up with the same answer and just the answer options lol
Lol got to keep you on your toes!!
It is truly a blessing the information you supply! Thank you. Why is XHHW and THHW listed in both 75 c and 90 c?
The first question i got it right and i did not have to look it up. That how good i I’m. Experience.
