I heard a comment that I still use when teaching this material. FLC = Full Load CODE, use the tables to size conductors, OCPD, devices. FLA = Full Load ACTUAL use for sizing the Overloads. Great little cheat, for remembering it.

Sure, the NEC sits there accessible in our rooms, work vehicles & classrooms etc. It's instructors like this gentleman, however, who inspire us to read and apply it to our work. Good teachers are a gift to the world, thank you for sharing, sir.

Agree. He's an outstanding instructor!

A very gifted instructor.

Thanks for all you do Ryan. One of the best instructors out there. Great video

Definitely. He's excellent!

Thanks! You're an excellent instructor. You clearly explain the concept, address the nuance, anticipate and answer questions, and explain the "why" and applications.. Excellent. I wish many of my flight instructors were as good.

@@RyanJacksonElectrical You're quite welcome, Ryan!

I really enjoy your videos. The topic is explained in a very logical and easy to understand way. Much better than procedural instruction given at school: you do this, then take this and based on that you do that because the table allows you this if that but not this because of that. Thank you. You helped another electrician to enjoy his job.

Ryan, always a pleasure watching you and I love the refreshers. Being a little bold and hopefully not requesting too much, I'd love a refresh on multi-motor crane calculations and arc welder calculation for conductor, etc. Again, thank you for everything you do for the electrical community!!!

One word, Just Excellent.

I watched the entire video it helped me better to understand article 430 about motors rules . Thank you..

Thank you, Ryan. Love your explanation and concept as it is easy to understand.

Awesome video, very informative! Thank you, Ryan.

Excellent video!! Thank you.

Thank you Ryan!

I'm a little confused about when to use the 430.6 (1) Exception No 3. 42 minutes into this video, there's a motor nameplate with both HP and full load current. Why are the NEC Part XIV tables used instead of the nameplate values?

I need to replace the service on my house, I am a union electrician, I normally do not do Residential work.I would like to see a video from you about what I need to know about arc fault breakers. I graduated from my locals apprenticeship program in 1996, way before arc fault circuits.

Nice build up to 430.6 - overcoming inertia

Thank you!

I'm glad I only have to size the circuit for my 6.5hp shop vac based on the FLC (13A). Otherwise it looks like I'd need an 80A 120V circuit for it!

is voltage drop a factor if the motor is 150ft, 30Hp 3Ph?

See you in Bay City once again!!

@@Jeremiah9909 Great idea! Part II of Article 225 is so misunderstood

I disagree with the too high of a value motor amps when connecting 2, 4 or 6 pole plain jane Nema frame motors that in my 50 years as a commercial electrician covered over 99% of installtions. Of the thousands of motors that I have replaced, moved, installed or PM'ed never came across a single motor that was within 10% of the NEC ampere. Just went 125% of the motor FLA & if a long run would calculate voltage drop and would increase wire size if needed. We had AHU'S that had two 60 to 125 HP motors where both supply motors ran 24/7 but seldom over 50% of full speed and on VFD'S. I could run over 1200 amps of AHU motors from a 800 amp distribution panel for 50 years snd never trip out the 800 amp breaker because of constant reduced speeds feed from VFD'S. Only time a supply motor ran close to full speed was when other motor was down for PM or rare replacement.

if you pulse DC power, you will get more out than in
