You have to use the correct screw when you secure a panel... I'm like what?
A feeder neutral conductor is not required at a panel or disconnect, unless the neutral is needed.
You don't need to adjust the ampacity for current-carrying conductors bundled in a panel [310.14(A)]
When more than three current conductors are bundled for more than 24", the ampacity must be adjusted
The NEC permits spare raceways from a panel and it does not require that an enclosure be installed.
Insulated neutral conductors 6 AWG and smaller must be identified white or grey per NEC 200.6(A).
