What Chapter 3 tables are used the most for residential?

[adamaero]

I am studying for the residential exam and wonder which tables will be more likely asked about than not. I also just want to know what tables are used by most in the field. Ugly's includes most of the tables from Chapter 3 of the NEC.

Unusual to use UGLY's as opposed to the NEC but for residential (or commercial) , 310.15(B)(16) is likely the most used (also the 1st one in my UGLY's) keeping in mind that NM has to be terminated at it's 60° rating..
It might aslo be worth noting the Dwelling Service Conductor Table in Example D7 in the NEC. I don't think that is in UGLYs

310.15(B)(16) (went back to just 310.16 in 2020 like it was long ago) is about the only chapter 3 table normally used for dwellings, along with any the accompanying adjustment tables in certain applicable circumstances.

I never like the ugly, that small print with everything jammed in alway got my eyes rolling. Easier for me to look in nec.

Annex C is a must, and must be paired with cheaper 9 tables
Practice off Annex D, it helps to look at those if you stuck will jar your memory.
250.122
250.66
310.15( c )(1)
310.15.(b)(1)
Those are the ones I look at the most.

Any table in the book may be needed, since its a test.

Maybe a reason it is called Ugly's?

Is used, vs. should be used creates a different answer. 314.16 should be used regularly 300.5

Get rid of Ugly's for exam prep, it's a great asset in the field but not a substitute for the actual code book on a desk.

On anther forum I asked this question, and one person replied with "whatever's in my Ugly's." Most of the tables are in there. So it was a fairly useless answer.

The problem with just referencing the tables is there are a lot of other things to go along with them. As far as "calculations" article 220 is a must

Table 310.12(A) would be another residential specific table of the nec to keep in mind

You need to know what table does what. So answering your question is mute cause you don’t know what they will ask in a test.
