Zack, how would one calculate the unbalanced load? I did a large new build union subdivision job where every home had a 200A panel and we undersized the neutrals 1 size. Also I believe the lugs on the meter base are rated for 90 degrees celcius right? what about the main lugs on the main panel, are they 90 degrees or 75deg? If they're 75 degrees (lets say we're doing overheard service) then I could use a smaller gauges of service wire from the utility to the meter, but id then have to upsize from the meter to the panel to make up for the lower temperature rating of the panel lugs (75) right?
I am setting up for a hot tub. I ran a #10 stranded copper wire for my neutral from my sub panel to my disconnect outside. The tub is 220-240V and it only takes 2 hots and a ground. In order for the GFCI breaker outside to work properly I had to run the #10 for my neutral. Is this #10 sufficient for this job? The run is about 45 feet. My hots are 6AWG stranded copper with ground. Thanks!
Hey! What article in the code book references the first 200 amps you mentioned?
4-018 2) b) in the 2021 CE Code

would this apply to sizing neutral conductors for light control panel as well? where all the branch circuits basically feed the lighting load?
What if I had a 200 amp breaker that consisted of 3 4 ought ungrounded conductors. What would be my grounded conductors be?
I can touch both line and load sides of a 200 amp service for 10 seconds it Jumpstarts me for the day~

You'd have to check with the manufacturers specs and the inspection authority
Good video. Thanks
Thx Zack, could you tell me the other things that come in play that you mentioned at the end of the video. Maybe just the codes references at least.?

Awesome.
Nice ! Are you filming through a glass screen ?
You are using "total Load" for "unbalanced load". I think that is wrong.
