@keything8487 4-6 is 80% which gives 12s 24A and then 7-9 is 70% which gives them 21A. The neutrals are included except for situations like balanced multi wire circuits I think or other times where the neutral load is minimal.
@@HerbieBancock When you derate THHN/THWN conductor (using it because it's pretty much all I see), you use the 90 degree column. 310.15(A) "Temperature correction and adjustment factors shall be permitted to be applied to the ampacity for the temperature rating of the conductor." THHN/THWN is rated for 90C.
Lmao I'm an apprentice.. Started less than two months ago. Last week one of our electricians was fucking with me and told me to wire the panel. He said "Hey, go ahead. Read the panel schedule and wire it." I was so lost. I told him over and over idk what I was doing lol. He said he didn't care he wanted it done. He saw me staring at it for a few minutes trying to figure it out and he started laughing. He's the only one so far that I've seen wire our high-voltage stuff and he's a legit badass electrician.
@@Reallymydaughter135 if you know how to actually control and impact, you aren't going to damage it. But some people think they are driving in wood/sheet metal screws and go full throttle. If you are using an impact on a panel, you shouldn't hear an impact when tightening screws.
I’ve always had a conflict at work on how to property connect neutrals when you have a let’s say 480 380 transformer. One of our panels was wired with the neutrals tied together. The other one was wired with just the neutral coming off the tap in the transformer. Which is correct.
It depends. Sometimes it’s the numbers of the breaker on the panel cover. Sometimes it’s just labeled what it is and where it goes. Depends on what the specs are and how good the electrical engineer was
Hey NEC how bout making it illegal to have an 'open' screw inside the box? IDK a small tube encapsulating the cover screw from hitting any conductor? wow Brainiacs with more time than brains!
@@jacobplyler3470 although they are technically code compliant in some cases, many AHJs I have worked under do not allow them. There is too much potential for neutrals to have amperage still running through it if you only open the breaker you are working on. It is fine to do with a 3 pole breaker but if you take those hots to different breakers and hardware it's dangerous for a tech working on the ciruits and has the potential to cause to much resistance on the neutral wire. Also when installing certain hardware these days you have to have dedicated neutrals.
@@jacobplyler3470 I just misworded my original post. I'm bad about that. Mean one thing and say another type shit lol. Just would have enjoyed the explanation that there are only some cases in which boats can be ran per code..... I might have honestly missed that in the vid once the Neutral PTSD kicked in lol
Need to keep in mind Table 310.15(C)(1) for derating. You can only fit nine CCC 12s in any size conduit before their ampacity drops below 21A.
ccc is the neutral included. i thought it was 6. then in 2023 - 3??

Under what circumstances are you getting away with looking at the 90 degree column to get these inflated ampacities?

Awesome as usual, my good sir. I have learned so much from this video. Thank you very much. 🎉🎉🎉
I enjoy your hands on videos! Thank You!!

Great video Dustin! I noticed you are using plug-on circuit breakers for commercial work - how often do you use bolt-on?
Love your videos, super helpful!
Can you talk about the why not to use impact tools in or on a panel!
i have not seen where a breaker lug is impact rated

Do you use a different color to identify the wire in case one leg was a high leg?
Is the membership still live
Do you know if the Siemens Inhab monitor provides API access or if it can integrate with third-party apps like Home Assistant?
Great video. Thank you for sharing. Happy New Year. May I ask, how many Amps for Commercial Breaker panel ?
You mention labeling the ends of the conductors to identify the circuit they are part of. I am curious what coding system to you use for this? Thanks.
It depends. Sometimes it’s the numbers of the breaker on the panel cover. Sometimes it’s just labeled what it is and where it goes. Depends on what the specs are and how good the electrical engineer was
16 #12 in a 3/4” conduit? Did you read that correct?
11:23 would be nice to get prices of these items you show us.

Where and how can I get this book? I'm from Jamaica 🇯🇲
It’s funny you saying “3phase” AS synonymous with “commercial” to me cuz they run 3 phase to residential where I live.
Why do you have a chemistry book?
I was told Red, black, blue but that be a Canadian thing
Emt isn’t a conduit. It’s a raceway. At least according to the Canadian electrical code

Blue Black Red Hello?
Rents due
Grouping of the grounded conductor with the ungrounded conductor is only required when it's a multi wire branch circuit.
Two exceptions relax grouping requirements for cables if the grouping is obvious and for un-spliced loops in conduit bodies or boxes.
You don't have to do this, but I prefer to put the heavier loads closer to the input terminals on the panel so as to reduce bus resistance.
I could have swore Boats were no longer code compliant, least in the AHJs I've worked in. I despise them after retrofitting big box stores lol
How are they not code compliant?
Yeah maybe he's thinking about sumthin else.

@@garrettmcbride7539 Yes, though there is a code that requires the hots to be on the 3 consecutive breakers and interlocked to prevent that.
