Four months ago I passed my Masters Electrician exam and I owe it all to this man right here. I went from being just a regular blue collar garbage man working for the city in NY to a licensed Master Electrician. Thank you for everything

Hi Coach This is Indiana Jones bud. I posted something to "You" about 3/4 months ago👍👈,you were Actually doing your Live class thing, And i had stated,you were doing a Very good thing in Life,by keeping Positive always,and I had stated A few other things,I think you Should remember, because i saw The motion on you're face,like, Man,it seems like I know this guy From somewhere?Anyhow,I have A Serious Electrical question for You sir
the load calc question regarding the 9 1600 sq. foot apartments i seen you applied a 35 percent but in newer code book it says in table 220.42 apartment houses the demand factor is 50 percent 20,000 to 100,000 va. Is this correct
How do you do calculation for a heat pump/ac with 10kw back up heat strips. Do you just use compressor motor and fan size since Ac and heat pump use the same compressor and fan then add heat strips to the calculation
Great question, Ac + fan motor. Heat-pump + strips + fan motor. On this original series I was not adding the fan into the heat, now with this type of question I do. The fan will never make the difference in choice but it is the correct way to do it.*
I noticed that there were no largest motor added to the Dwelling calculations. I'm not sure if I'm missing something like motor HP wasn't part of the question. Thanks for your videos, they're helpful.
If I'm understanding your question correctly, you will only calculate what they give you in the question. Sometimes on exams they will give you many variations of a load calculation. Sometimes they want just a little bit of the process sometimes they want it all, but never make any assumptions or add anything that is not there. Please let me know if I answered correctly!
@@ElectricalCodeCoach Thanks again for all the videos and your response. In the standard method, 125% of the largest motor is added to get the total VA demand load for a dwelling.
Another question? So Im doing a load calc on a 9000sq foot house.. I know they have two tesla car chargers going in and a hot tub? Do I add those in as well, Like all the info can get or just use the basics?
If i am understanding your questions correctly, yes you could use the total amperage to select the correct overcurrent protection to cover the load first... then you could take that overcurrent size and multiply it by .83 and size your wire by that new amp load. if it were a single family dwelling unit or the individual units of a multi family dwelling unit. Great Question!!
What about required bathroom circuit? And as that fellow asked before wouldn't the blower motor be included in the calculations with the heat strips which would make your answer incorrect testing or real world? Don't get me wrong I really appreciate these videos!
Excellent questions! The required bathroom circuit nor the required garage circuit have to be calculated as a single 1500 VA allowance. They are allowed to be calculated in the general VA's for now, I look for that to change in future code Cycles And yes you will include the blower motor if it is listed in the question if it's not listed in the question you do not add it. When you're doing your testing you just calculate what they put don't do any assuming when testing!

This makes my heart swell with happiness! I am so proud of you! Thank you for the kind words!
Thanks a lot. These videos are awesome. Much easier to understand and follow than some of the other stuff I’ve found on here.
Awesome video.
Thank you so much this is really helping me out , a lil closer to passing this nec exam
You are welcome brother! Keep grinding!! And thank you for your support!
Hello, quick question on the 27 appliances for the 9 units, where do you get 4 or more 75% rule. I’m not seeing it on the NEC2017
It's four or more, per electrical service. Since we're calculating the main service we're allowed to use it
I don’t understand how come we adding blower to AC compressor calculation but not to heater strips? Aren’t we using air blower in both cases?

Hi Coach This is Indiana Jones bud.
I posted something to "You" about 3/4 months ago👍👈,you were
Actually doing your Live class thing,
And i had stated,you were doing a
Very good thing in Life,by keeping
Positive always,and I had stated
A few other things,I think you
Should remember, because i saw
The motion on you're face,like,
Man,it seems like I know this guy
From somewhere?Anyhow,I have
A Serious Electrical question for
You sir
Shoot. whats the question?
@@ElectricalCodeCoach On my
Exam there's a question about
"Does a furnace require a switch
I will check when I get back in the code book at 4 a.m.! Hope you did well on your test today!
the load calc question regarding the 9 1600 sq. foot apartments i seen you applied a 35 percent but in newer code book it says in table 220.42 apartment houses the demand factor is 50 percent 20,000 to 100,000 va. Is this correct
Great video!!!
Thanks brother! And thank you for the support!!
Coach, when do we apply the 125% to the AC calculation. I see some calculations it’s used, and other it’s not? Thanks!
I dont use it any more

@@ElectricalCodeCoach Thanks again for all the videos and your response. In the standard method, 125% of the largest motor is added to get the total VA demand load for a dwelling.
Are you using PIE or Ohms law ? You multiplied I and E , that’s P I E correct ? Ohms would be division between I and E , no ?
Another question? So Im doing a load calc on a 9000sq foot house.. I know they have two tesla car chargers going in and a hot tub? Do I add those in as well, Like all the info can get or just use the basics?
Excellent question! Yes you will add in the Tesla and the hot tub and all other known loads! I appreciate you taking the time to stop by the channel!!
@@ElectricalCodeCoach always do... You make the NEC A LOT easier to understand..
Also when you're finished with your calculation to determine your feeder size do you use the 83% rule then
If i am understanding your questions correctly, yes you could use the total amperage to select the correct overcurrent protection to cover the load first... then you could take that overcurrent size and multiply it by .83 and size your wire by that new amp load. if it were a single family dwelling unit or the individual units of a multi family dwelling unit.
Great Question!!
This is great. I want to be an electrical inspector can you help???
Absolutely! Work through the program and you'll be able to go take your test!

Thank you so much for your timely reply ! Please keep up the good work !!
you will need to add the blower motor to the heat!?
Yep if there is a blower motor listed in your question! In the real world you calculate what ever is there! Thanks for the comment!!
Sorry , it’s part of ohms law . AMG , so sorry
