Let's go!!!

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 KZread, i appreciate what you do.

When calculating the general lighting load, how come we still add the 4500 for small appliances and and laundry?

It is truly a blessing the information you supply! Thank you. Why is XHHW and THHW listed in both 75 c and 90 c?

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

Is it possible to edit in "Standard Method" in red, as in your other videos, for the questions at 24:56 and 28:26?

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.

@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!!

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

2.25 x 2 = 4.5

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

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

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
