Using panels for a pull box.

Can you run feeder conductors for a panel through another panel? I can't find out where it says you can't do this. Also, according to 250.119(A) EGC's larger than #6 can be identified at each end at the time of installation, does this mean that conductors#6 and smaller must be a continuous green the entire length?

Yes you can run feeders thru a panel as long as there is room for conductor fill.

Yes, green all the way

where do you find the conductor fill for a panel? do you have to take measurements and apply a %?

312.8
I don't recall the %s off the top of my head.

312.8 Enclosures for Switches or Overcurrent Devices.​

Enclosures for switches or overcurrent devices shall not be

used as junction boxes, auxiliary gutters, or raceways for
conductors feeding through or tapping off to other switches
or overcurrent devices, unless adequate space for this purpose​

is provided. The conductors shall not

fill the wiring​

space at any cross section to more than 40 percent of the

cross-sectional area of the space, and the conductors,
splices, and taps shall not​

fill the wiring space at any cross​

section to more than 75 percent of the cross-sectional area
of that space.
