    Using 310.15(B)(16) for Less Than 100A

    All,

    I know somewhere in the code, it states for circuits 100A or less, you are to use the 60-degree C column for selecting conductor size but can't seem to locate it.

    Any help finding will be greatly appreciated.

    Thanks,

    Steve

    but note the 75° column can be used if all terminations are rated 75°
    At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.
