Really appreciate the following here man: (1) Video is under 5 mins; (2) drawn example; (3) kept it simple (4) added an asterisk to explain the "real world" code scenario.

Incredibly helpful! I encourage you to do more of these short videos connecting the install to the design.

[larrybland]

Bro I learned more from you Channel in a month than I have at work for a calendar year!

[scrublet]

Learned this during my electrical course a while back. This was a great refresher. I also liked how you added the code rule

[njphil]

This applies for any basic resistive loads but heating elements (old school light bulbs, toaster ovens, etc..)change resistance as they age and heat up. Naturally if the resistance changes, the wattage follows. Guess that's why you use the 80% rule. Another good thing to mention is the new LED bulbs can't simply follow your rule because the power supply consumption, either discrete or within the bulb itself, needed to drop the volts to run the LED isn't included in the bulb rating. Although negligible, a 4W LED might consume 12W of actual power.

Good stuff here. I'm a EE, mostly digital, and grew up on this stuff. My kid would be just like you had he follow my profession and not gotten into software. Nice how you teach the noobs on how to do shit the right way. To many hackers out there that don't know what they are doing

[kaminoshi]

I subscribed off of an earlier video, I’m already appreciating the choice and the content.

[MrAcacio]

Thank you. I will remember to do that before install a lamps.
Couple months ago, I was asking this question and I try to research on the web, but you are the Man. The best and simple explanation. Thank you brother.

[TheLoboindio]

You had me going there for a second I thought you were going to drop the ball. But then right at the end. U drop the 80% rule. Good vid!!

[ReggaeRedeemer]

This one is super crucial for someone that is starting to do small side work jobs

[MagneticPerturbation]

Good catch on the 80% continuous load requirement in NFPA 70. I started to type up a comment of reminder just as that ad hoc text block came up. Understanding basic algebra and going through the longer training (including math theory) are necessary a priori to the shortcut methods imho but the shortcuts definitely have their place. Like in depth code classes are important before you can default to Ugly's for brevity. Keep up the good work and never stop learning. Liking the channel.

[getwrxed]

That was an amazing video dude, short simple and straightforward

[TechWizard]

Short and informative. I like it. Adding to favorites.

[MiddaJoice]

Great video, i feel like i learned more in 2:59 then i did all day in apprentice school.

[ceasarcastaneda]

Can you make more videos like this to help out those starting to work with electricity. This was helpful.

[charlespatt]

I learned the charts when I was 12, never forgot them for the next 54 years.

Also, I found could always remember the order of the letters because, well, PIE spells pie. And EIR happens to be in alphabetical order. It was helpful for a 12 yr old kid who just got his ham license.

[jacobwalkup]

Can you do a video on digital multimeters vs clamp meters? And which you need for what you do.

[slaughify]

You are a very good teacher. Thank you

[franciscoc]

First year apprentice that’s just learned ohms law… thanks for giving me an in-field example

[Clyde]

I woke myself up this morning thinking about a home reno and the microwave/range hood combo that the customer is having installed, I grabbed my phone and did quick Ohm's law math to make sure I had the right breaker and wire installed. I did, woke myself up for nothing but it's always good to double check.

[nafizkhan]

Thanks for the video. Another thing to note is the inrush current which could cause nuisance tripping..

[zanelewis]

Love the content brother! This may be petty but i think these explanation type vids might benefit even more without the background music. Thanks again for all that you do
